Today, I got the KZ DQ6. This IEM contains 3 dynamic drivers per side, which is a bit different than the usual BA and dynamic drivers combination they usually make. It is made of a single 10mm “Xun” unit that handles the bass and 2x 6mm drivers that handles the mids and treble. KZ is well known to experiment with different driver configurations and this is no exception. We’ll see how they perform below.
The box is the usual we get with KZ IEMs. It’s small and practical.
In the inside, we can see both units. The form factor is similar to their previous KZ ZSX “Terminator”.
We get the usual offering with these IEMs: A silver 0.75mm 2-pin cable, which is what KZ is now packaging, the tips, and the usual instruction manual.
The headphone tips are no longer the “star” tips. Rather, they decided to change them to a soft white tip. Unfortunately, these tips are way too soft and they make the DQ6 not fit the ear properly. This is no problem, as most would use third-party tip, but there is actually another problem: The nozzle diameter is smaller than the previous KZ IEMs, making some of the tips not compatible with them.
I tried the SednaEarFit Light to replace the stock tips, but the nozzle diameter of them are bigger than the KZ DQ6 and therefore, they would get out and not seal properly. Fortunately, the SednaEatFit Xelastec fits as well as the Spinfit CP100:
This IEM has a great tuning and I consider it an improvement over their latest hybrid IEMs. In the bass region, there is more presence without being overblown or being too fast. The mids are less recessed. Vocals are clearer, not metallic and warmer. The treble sounds extended without being sharp and fatiguing, something I had issues with their hybrids. The instruments are very well separated and well coordinated. None of the frequencies dominate the audio and seem to work together to produce a beautiful, musical, detailed, warmer sound.
I also own the KZ ZS7, ZS10 Pro, AS16, ZSX and ZAX, and I feel these DQ6, while being cheaper and having less drivers, do sound better than all of the previous mentioned models. I can also listen to these for more time without having ear fatigue. For me, these are the most balanced KZ IEMs I have ever tried.
It’s interesting to see KZ try something different than their usual hybrids. They nailed it with the tuning on these, really! Just be sure to change those stock tips to something better like the SpinFit CP100 or the SednaEarFit Xelastec. You’ll note how comfortable they will be and the sound will not disappoint you.

Hidizs adds support for MQA on their AP80 and AP80 Pro DAPs
Today, I’ll present you the Oakcastle CD100 Portable CD Player. Yes, a CD Player, and this one has Bluetooth in it. As you may know, nowadays people use streaming services to listen to music, which includes services with lossless audio quality. However, some people also prefer to buy CDs and listen to them, as some may argue that CDs offer better quality than lossless streaming services. Others buy them to collect them.
I’m one of the few who prefer to listen to Audio CDs, collecting them if I find it worth it after listening to them on streaming services. I do listen to them, but on my PC, as I didn’t have a CD player. My last one died lots of years ago, probably due to battery leakage. Thankfully, CD players are still being made and now comes with a rechargeable built-in battery, but the biggest new feature that’s coming to them is Bluetooth audio transmission. This is really important because, in a world that has shifted toward digital streaming and Bluetooth headphones, this means we can pair them to this CD player. It also means we can pair it to cars that no longer have an internal CD player.
I was suprised by the small, simple box.
Opening and starting to take out what’s inside, we first see the instruction manual and the CD player behind:
The box on the left contains all of the cables and the included in-ear headphone:
The CD player is very well protected with a foam container:
Let’s take a look at the CD optics:
This CD player states that it can read Audio CD, CD-R, CD-RW, and discs containing MP3 files. I have tested it with some burned CD-Rs and can say that it works flawlessly. My discs are specially burned because I tend to create a LabelTag label on the data side. These discs are therefore considered multisession discs, as the label counts as a session on the disc structure. The CD player could read it without any issues at all.
The audio quality is very good, both when connected to the 3.5mm jack and when using Bluetooth.
The volume is very loud, so the IFI IEMatch comes in handy here, to reduce the volume by -24db. The Bluetooth sound is very clear. The difference I noticed is that the bass is a bit less present. It’s there, but it’s just not as dynamic as when using the headphone jack. The treble, on the other hand, seems to be the star of the show, along with crystal clear vocals. Maybe it’s the treble that may be shadowing the bass. Overall, everything sounds finer, even considering that it only transmits audio using the SBC codec.
The CD player charges via USB at a max of 1 amp. This basically allows you to use any USB charger you may have around. You can also use it while charging it.
My first impressions of this product are very positive. I’m pleased with the sound quality, both wired and on Bluetooth. It paired easily with my FiiO BTR5 and Hiby W3, both of which use a Qualcomm chipset. This means it should theoretically pair with headphones and receivers having one of their chips.
This CD player can also read MP3 files, and it worked really well on these discs too. It does take a second or two to load it, but works, and the audio quality is also very, very good. I just wish the next generation of players can read FLAC files directly too.
Regarding the battery life, I’ll play audio CDs non-stop to know how much time I can listen to music without having to recharge it.
UPDATE 3/26/2021: This CD Player can also play WMA files.
So far, I’m really impressed with it.
You can order this CD player on Amazon at the following link:
Yesterday, I wrote about how my 2020 was in terms of audio gear. Today, I’ll be talking about my initial purchases and what’s to come over the next few days and weeks.
I’m always looking to try new digital audio players and DACs mainly, followed by some headphones, usually from KZ. This year, I’m starting it with new products from Hiby, Hidizs, and Fiio. Let’s see the products below.
The Hiby R2 is Hiby’s newest ultra-portable player, which has most of the features of the R3, but in a smaller body. It is able to decode and render MQA, and can stream music from Tidal via Wifi. I’m a huge user of the Hiby R3 Pro Saber, so I’m really exited to give the R2 a try!
The Hidizs H1 is a neckband Bluetooth cable that comes with the Hidizs MS1 Rainbow. For the price, it is a real bargain, considering you get both items and also considering that most people will already have 2-pin 2.5mm or 3.5mm cables. Since I already own the Hidizs MS1 and MS4 which I backed on Kickstarter, the MS1 Rainbow is the only one I still don’t own. I also already have Hidizs’ 2.5mm and 3.5mm cables, as well as their BT01 Bluetooth cable. This means that this cable will be new in my collection. The Hidizs H1 is also compatible with the Hiby Blue app. It supports the SBC, AAC, aptX and aptX Low Latency codecs.
The Hidizs H2 is Hidizs newest Bluetooth receiver adapter. It shares a few design details from Hiby’s own W3 adapter, having physical buttons as well as the LED which will be green or blue depending on the audio sample rate. It supports the main Bluetooth codecs, while also having support for LDAC and Hiby’s UAT codec. The Hidizs AP80 and AP80 Pro, as well as Hiby’s products already support UAT, so it is guaranteed we will have the best audio quality when listening on those products with the Hidizs H2. It also supports the Hiby Blue app and can also be used as a USB DAC.
The Hidizs S9 is Hidizs newest DAC, sporting an AKM AK4493EQ DAC. It has both 2.5mm and 3.5mm outputs and supports up to 32bit/768Khz.
The FiiO BTA30 is a Bluetooth receiver and transmitter. It claims to transmit audio using LDAC when using an optical or coax cable. My main purpose of this product is to attach it to my TV and see how much the audio quality improves and to try LDAC with it.
And that’s my initial purchased for products I should be receiving in the next couple of days. The Hidizs S9 is the product with the most far date, presumably due to AKM DACs shortage due to their factory fire. I’ll patiently wait, and I’m really looking forward to try all of these new products.
Last year was a great one when it came to acquiring new Audio Gear. In this post, I’ll talk about my acquisitions with a bit of overview for each product.
Digital Audio Players
In 2020, I got the FiiO M5, the Shanling Q1, the Hiby R3 Pro Saber, and the Hidizs AP80 Pro. These 4 companies do great products, so I went ahead and ordered their newest products. I had the Shanling Q1 already preordered on Kickstarter.
The FiiO M5 is a hybrid DAP. I say it’s hybrid because it also has a Qualcomm Bluetooth chip inside that makes it work as a Bluetooth receiver and transmitter separately. While products like Hiby and Hidizs DAPs also have Bluetooth receive/transmit functions, these work entirely using their Ingenic X1000E CPU and their Bluetooth chip, while the FiiO M5 uses its CSR8675 chip for this purpose.
The sound quality of the M5 is musical, using an AKM AK4377 with Velvet Sound, which seems to focus on mid details. The only downside is that a USB DAC cannot be used when using it in Bluetooth receive mode, and that it does not supports Opus files.
Hiby R3 Pro Saber
The Hiby R3 Pro Saber is a derivative product from the Hiby R3 Pro. Its main difference is that it uses 2x ESS 9218p DACs as opposed to the dual Cirrus Logic DACs found in the Hiby R3 Pro. Hiby claims the R3 Pro Saber offers a more analytical sound, and I can describe the sound as being more airy and open than the R3 Pro. This has been my favorite DAP to this date.
Hidizs AP80 Pro
The Hidizs AP80 Pro is the successor of the original Hidizs AP80 (pictured on the left). Its main difference is that it now offers dual ESS 9218p DACS and the Hiby HBC3000 FPGA. These same DACs and FPGA are found in the Hiby R3 Pro Saber, but they sound completely different. I would describe the sound of the AP80 Pro as being more warmer, especially in the bass, while the sound of the Hiby R3 Pro Saber is more open and fuller. I think that the AP80 Pro would fit those who seek deep bass while the Hiby R3 Pro Saber fits those looking for a more musical and open sound.
The Shanling Q1 (Pictured in the bottom center) was launched in Kickstarter. This player didn’t had Wifi until a later update added it with the DLNA feature. It also uses an ESS 9218p, but sounds different than the Hiby R3 Pro Saber and Hidizs AP80 Pro. The sound seems to be centered around mids. It sounds good, but different at the same time. The only downside is that the headphone jack is right in the middle and it is slippery. The buttons are also sensitive, but otherwise it’s a good DAP.
DACs and Dongles
Moving to the DACs and Dongles category, last year I got the new Tempotec BHD, the IFI Hip-Dac, and an off-brand very cheap DAC that’s surprisingly good.
The IFI Hip-Dac is an affordable DAC with a Burr-Brown DAC. It also renders MQA. Its sound is warm. On the back, it has a USB-C port which is only for charging, while a USB-A Male port is used for data. I rarely use this DAC because of the weird ports and I’d rather prefer it having 2 USB-C ports rather than its USB-A port. On the good side, the analog volume potentiometer works great, but be careful with sensitive IEMs as the volume gets extremely loud!
Tempotec Sonata BHD
The Tempotec Sonata BHD can be considered a “successor” to the Tempotec Sonata HD Pro. This one has dual Cirrus Logic CS43131 and has a 2.5mm output. It also shares the independent volume controls as the HD Pro. On the downsides, this one doesn’t have a detachable cable, and like the HD Pro, it has few volume steps. On the good side, it shares the same sound signature as the Tempotec Sonata HD Pro and doesn’t get warm.
Geekuy USB DAC
This one was a surprise find on Amazon. It is very cheap, considering it has an XMOS controller and an ESS DAC. It also features a 3.5mm output. For the price, I was surprised at how good it sounds. It also doesn’t generate heat, is USB Audio Class 2.0, and works great with the PC. However, it had compatibility issues with my DAPs.
In this category, I got the FiiO UTWS1 (My favorites!), the Shanling UP4, the Qudelix 5K, and the new TRN BT20S Pro.
The FiiO UTWS1 seems to be a rebranded TRN BT20S with a different button configuration and better volume control. Its advantages are a more functional button configuration that includes raising and lowering the volume. This is the most warm Bluetooth adapter I have, which would satisfy bass lovers.
The Shanling UP4 is yet another product using dual ESS 9218p DACs. It, again, sounds differently than other products with the ES9218p. This time, it is warmer yet musical at the same time. When compared to the similar FiiO BTR5, which also uses the same dual ES9218p DACs, the sound of that one is more analytical, working best for treble and more analytical detail retrieval, while the Shanling UP4 works best for concert-like music and to be immersed into the music experience. It has a volume knob and supports major Bluetooth formats, which is standard in this kind of products nowadays. It also supports USB DAC functionality up to 16bit/48khz due to it its Qualcomm CSR8675 SoC.
The Qudelix 5K is made by a team of people who, according to sources, are the same ones who did the original EarStudio ES100 Bluetooth adapter. The Quidelix 5K is unique in that it uses the newer Qualcomm QCC5124 SoC versus the usual CSR8675 that others use. It also supports USB DAC mode up to 96Khz due to the improvements of the chip. It, again, uses dual ES9218p DACs, but sounds different due to the implementation used as well as their DSP processing. It sounds clean and not harsh. My only complaint is the button learning curve.
TRN BT20S Pro
The TRN BT20S Pro is the successor of the TRN BT20S. They now include their own charging case which replaces the Micro USB port on the units. The hooks are also replaceable shall they go bad or you’d like to switch from 2-pin to MMCX. Unfortunately, it doesn’t play well with my phone as the volume is too loud. They also still have some hissing noise that’s also noticeable in their previous versions.
The only Bluetooth transmitter I purchased last year was the Avantree DG80.
The Avantree DG80 supports aptX Low Latency, as seen on the FiiO BTR5 on the right. It is a small dongle that transmits audio from a PC or other devices supporting USB Audio Class 1 products. I’ve been an Avantree customer for some time due to their excellent transmitter and receiver devices, and their excellent support.
Last year, the only headphone acquired was the KZ ZAX.
The KZ ZAX uses 8 drivers per side, consisting of 1 dynamic driver and 7 Balanced Armatures. The sound profile is V-shaped. It sounds somewhat similar to the KZ ZS10 Pro, yet more refined and doesn’t have a metallic sound that the ZS10 Pro suffered from. The sound is clean too and I sometimes listen to this over the Hidizs MS4, which are the ones I use the most. They retrieve a lot of detail in the music despite their V-shaped signature. On the downside, they do not isolate sound as well.
Late in 2019, I ordered the NiceHCK Spiral tips, which I received early in 2020. Later in the year I ordered some tips from AZLA.
NiceHCK Spiral Tips
The NiceHCK Spiral tips have a spiral form in them. I ordered them after comparing them to other tips and making the nozzle close to the ears. The sound isolation is very good and improves bass in most cases.
I brought these tips accidentally, because it resembled the bass tips of the Hidizs MS4. Turns out the nozzle stays far from the ear, but they did improve the sound stage.
AZLA SednaEarFit Xelastec
Made from a different material than silicone, these have a sticky feeling. I wrote a more detailed review of these that you can find here.
And that was my 2020 in music gear. In my next post, I’ll talk about my acquisitions for 2021 that I will be reviewing as I receive them.
I haven’t received most of the products above, so keep looking forward to my reviews over the year too along with my new 2021 gear!
Ever since I got my Hidizs MS4 IEM, I became a journey to try several ear tips, after I lost one of their “Bass” ear tips. This journey began with me trying some Chinese replacements tips, in particular, some called “Spiral ear tips”. They were good, but I still tried other tips, including the highly acclaimed Spinfits.
Unfortunately, I wasn’t pleased with the Spinfits, as I found it degraded the sound to my likes. It was until I found the AZLA SednaEarFitLight that I was really pleased with how the sound came from them.
AZLA is known to make one of the best ear tips. Their SednaEarFit line improves both sound and comfort, but one of their issues has to do with getting the right fit, and the high price. However, once you find the correct size for you, you will be really pleased with how they sound.
AZLA recently released the SednaEarFit Xelastec, which is made of different material that adapts to your ear. This makes them fit great and will not, theoretically, fall.
I found that one of the most important thing that affects the size is the nozzle size and diameter. The smaller the diameter, the more dull the sound will be, and the longer or shorter the nozzle length is, is how the sound frequency will get affected.
On the Hidizs MS4, the shorter the nozzle length is, will produce more bass, great mids, and tame the treble. The longer the nozzle length is, there may be less bass, with more treble sparks, and the mids, well, fall in the middle or may get behind.
Once I tried the SednaEarFit Xelastec, they became my favorite ear tip. Here’s why:
Ease of use
Some ear tips have a hard time getting placed in the IEM nozzle, because of its diameter. This was the case when I got the Spinfit ear tip, as the diameter was small. With the SednaEarFit Xelastec, they just fit without having any struggles. This may be due to its adapting material.
The nozzle length of the Xelastec is shorter and just a bit smaller than their SednaEarFitLight. However, due to the material it’s made, the sound doesn’t get affected much. In fact, it does a great job to reproduce a great frequency response. The bass isn’t overwhelmed but is improved. The mids comes more forward but not too much. The treble is tamed with no sparks to it. The sound stage is very good to my likes, which is a forward sound with great instrument separation and energy.
This really depends on the tip size used. In my case, the best size is their ML (Medium-Large) size. They are very comfortable and fits very nice in my ears. I can use them for hours without getting itchy or without causing discomfort. They also do not fall. The material they are made will give you a sticky feeling, unlike silicone tips which depending on the one used, may cause you some itch and discomfort.
The only downside is that due to them being kind of sticky, you may have to clean them often.
Let’s be honest, these tips are not cheap, but they are really worth it. The main problem you’ll probably face is spending money to test the different tip sizes. I used to be a medium size when it comes to tips, but for the AZLA tips, the best ones are their Medium-Large. Fortunately, you can get various tip sizes but at a premium.
Personally, I got the pack that comes with medium, medium-large, and large tips, just to see if the medium-large would still fit or I needed to go down to the medium tips. The large ones are large indeed.
So, for starters, you may want to start here. At a price of $28.00, each tip size comes at $9.33 approximately.
I can recommend these tips if you’re looking for comfort without compromising the sound. It may even improve it depending on which tips you are using. Remember that not all tips will produce the same sound with every IEM, so your mileage will vary here, but if you, like me, own the Hidizs MS4 IEM, I can recommend them. AZLA makes one of the most amazing and high quality ear tips I’ve ever used.
You can get these tips on Amazon here:
Comparison of the sound of the different Hiby R3 models
Today, I want to talk to you about the different sound signatures of the different Hiby R3 models.
Hiby is a company that specializes in audio hardware and headphones. They have created Digital Audio Players, Bluetooth receivers, and headphones. They have also created a modified Android version for their Hiby R5 and R6 players while also having developed the HibyOS operating system that powers the Hiby R3. They also use a range of DACs in their products that ultimately gives them their signature sound.
Two years ago, Hiby launched the Hiby R3 player on Kickstarter. This particular model used an ES9028Q2M DAC. It also offered a lot of great features for a price of just $189 at that time. Then, in the last months of the last year, Hiby launched the Hiby R3 Pro, changing the DAC to not one, but 2 Cirrus Logic CS43131. Finally, a few months ago, Hiby launched the new Hiby R3 Pro Saber which went back to using ESS DACs. This time, powered by two ES9218p DACs.
These players each have their advantages in the sound department, but none of them sounds the same. This is why I’ll be giving my thoughts on this.
The original Hiby R3 is musical in the mids. The highs are not bright and the bass is not overwelmed. The sound is neither warm or bright, but rather neutral. This is why it seems like the mids have a better presentation.
Hiby R3 Pro
The Hiby R3 Pro changed the DAC to dual CS43131. Cirrus Logic DACs are warmer than those from ESS, which sounds more analytical and sometimes bright. Because of this, the bass and mids have a warmer tone, including making the vocals be warmer, The sound is also a bit more open due to the two DACs.
Hiby R3 Pro Saber
The Hiby R3 Pro Saber went back to the ESS DACs, particularly, the ES9218p. These DACs sound different depending on their implementation. On the Hiby R3 Pro Saber, the sound is more analytical, airy, and more open. The hights are bright but not to the point where they will cause hearing fatigue. I rather like the sound this way because it makes the highs be more detailed. The voices have a lot more air and are more forward and clearer than on the R3 Pro, which was warmer.
Below, you’ll find a video I recorded talking about these different models and their sound signature:
Which DAP is your favorite? Let me know in the comments.
This is a Bluetooth adapter that works as a PC audio card. It transmits audio via Bluetooth using the SBC, FastStream, aptX, or aptX Low Latency codec, depending on which codecc your headphone or adapter supports. Having the aptX codec provides us with a better audio experience.
The aptX Low Latency codec allows us to watch movies and videos without any audio delay. Most Bluetooth receivers today support this codec and having a transmitter with it makes us take advantage of this.
The DG80 packaging is small and simple.
We can see the adapter along with its manual and documentation behind.
We can see the transmitter is really small.
Finally, we have the included documentation.
Using the transmitter
Using this transmitter is as simple as plugging it into a USB port and going into pairing mode.
We can see Windows detects it as Avantree DG80.
The transmitter has a bit depth and sample rate of 16bit/48khz, which is common with these adapters.
I paired it with my Fiio BTR5 and we can see it is using the aptX Low Latency codec.
Here’s a video of the pairing process of the adapter:
Becuase this transmitter uses a Qualcomm chipset, the sound quality is realy great, thanks to its support of the aptX and aptX Low Latency codecs.
Avantree claims the adapter will work up to 30 meters or 100 feet. This may be true unless there are some obstacles in the way. In my tests with the Whooshi adapter, known to have signal issues, I was able to listen to music while I was in the same room. However, going away I could hear the audio getting cut. If you’re looking for the best signal range, the Avantree DG60 is a better choice.
If you still do not have a USB Bluetooth audio transmitter, the Avantree DG80 is a good start. It’s small, portable, and cheap. It also supports the aptX and aptX Low Latency codecs to provide excellent audio quality.
