This device usually retails for about $59, but today, you can get it for just $49. That’s the same price of the 3.5mm version!
If you’re an owner of sensitive IEMs, you may have experienced the problem where you hear some background noise, or the volume control stepping is really bad. It is either too low, or too high, with no middle point. This little adapter will reduce the hiss and noise from the audio source in which it’s being used, as well as helping you at having better volume control.
The IFI IEMatch 2.5mm is basically the same as its 3.5mm version, except that it is designed for use with 2.5mm sources. It has the same 2 operational modes: High, and Ultra. High reduces the audio volume by 12db, while the Ultra setting reduces the audio volume by 24db.
I’m an owner of the iFi IEMatch 3.5mm version, and use it with my Hidizs MS4 in the Ultra setting. It works wonderfully when used with some USB DACs that are way too loud when used with this sensitive IEM.
Since I now own a 2.5mm DAC, and another one is in the way, I’ve decided to take advantage of this sale to use it with my 2.5mm DACs and have better volume control.
I’ll write another post detailing the improvements of using this with my DACs. In the meantime, you can take advantage of this sale by clicking on the link below:
Using the Hidizs MS4 with the RevoNext 3 5mm cable with inline controls and mic.
I’ve uploaded a new video to my YouTube channel where I’m showing the Hidizs MS4 IEM being used with the RevoNext 3.5mm cable that has a microphone and inline controls to control volume and media. The cable that comes with the Hidizs MS1 and MS4 does not have a mic or inline controls and this cable is perfect as it adds those 2 things.
Watch the video below:
You can get the Hidizs MS4 and the RevoNext 3.5mm cable at Amazon using the following links:
Using the KZ aptX HD Bluetooth Cable and the TRN BT20 with the Hidizs Mermaid MS1/MS4
Today, I recorded a video showing the new KZ aptX HD Bluetooth Cable and the TRN BT20 Bluetooth adapter with the Hidizs Mermaid MS1/MS4.
The reason of doing this video is to show how the KZ cable fits the Hidizs MS1/MS4 as the KZ cables comes in different pin flavors. And as for the TRN BT20, I just wanted to show how they look with it attached.
It’s nice to have a variety of Bluetooth adapters to use with these new IEMs which have an incredible sound.
You can watch the video below:

The Hidizs Mermaid MS1 and MS4 IEMs with their cables and accessories
Yesterday, I received the brand-new Hidizs Mermaid MS1 and MS4 In-Ear Monitors Absolute Kits.
The Hidizs Mermaid MS1 is an IEM with 1 Dynamic Driver, while the Hidizs Mermaid MS4 is an IEM with 1 Dynamic Driver and 3 Knowles Balanced Armatures.
My initial impressions are excellent. These IEMs do a lot to reproduce the music. I found that the MS1, with just the Dynamic Driver, produces a warm sound with great mids and smooth bass and treble. The MS4, on the other hand, improves the bass and treble while having great mids. Since the MS4 uses 3 balanced armatures for the mids and treble, they do a great job, and since the Dynamic Driver is focused on the bass, it also does a great job. The MS1, on the other hand, produces a warmer sound since the Dynamic Driver needs to reproduce the entire frequency spectrum.
The Hidizs Absolute Kits come with a choice of a 2.5mm or 4.4mm balanced cable, USB-C 2-pin cable and an aptX Bluetooth Cable using a CSR8645 chipset. They are also compatible with other 2-pin 0.78mm IEMs and you can also use other aftermarket cables due to their 2-pin connectors.
The IEMs can be driven easily since the MS1 only has an impedance of just 15Ω while the MS4 has an impedance of just 12Ω. However, you can use your favorite DAC like the Hidizs DH1000/Tempotec Sonata iDSD Plus and use the balanced output to enjoy an even better sound. You can also use them with the 3.5mm cable with the Hidizs AP80.
Now, here’s my unboxing video I recorded yesterday where I unbox both kits, their cables and accessories:
I personally like the MS4 due to their more punchier bass and their extended treble. The MS1 have more forward vocals, so if you’re looking for that, the MS1 is for you, but if you want the treble and a bit more bass, go for the MS4.
Here’s the review video I also recorded with my thoughts on the IEMs and the cables:
Overall, Hidizs did a great job with these new In-Ear Monitors.
You can purchase these 2 Hidizs IEMs at Amazon using the following links:
Today, I’ll be reviewing the TRN BT20 Bluetooth adapter for 2-pin In-Ear Monitors (IEM):
The TRN BT20 is a Bluetooth 5.0 adapter that is available in 3 different versions:
The version I purchased is the 2-pin 0.78mm for my KZ ZS7 IEM’s.
The adapter syncs together to bring you stereo sound. It uses a Realtek Bluetooth 5.0 SoC that while it is not specified which specific chipset it’s being used, I suspect it may be using the Realtek RTL8763B.
Because of it using a Realtek chipset, it doesn’t support the aptX audio codec, but it does support AAC along with SBC. This means that when paired with an iPhone or Android device, it should use AAC instead of SBC, and for backward compatibility, the SBC codec will be chosen if a device lacks the AAC codec.
The packaging is very simple, as can be seen in the following images:
Here, you can see the sides:
And here you can see the back:
To open it, you have to slide the box outside:
Opening the box, both pieces of the TRN BT20 are revealed:
As you can see, they are very well protected and can be easily taken out:
Continuing unboxing the box, we need to take out the cable and manuals which are after taking out the following:
There’s a Micro USB Y-Cable that allows us to charge both Bluetooth pieces at the same time:
Finally, we have the manual, warranty card, and the card that says it passed quality checks:
Using the TRN BT20 with the KZ ZS7
I was using my KZ ZS7 IEMs with a Revonext 3.5mm 3-button cable before using this TRN BT20 Bluetooth adapter.
I removed the IEM from the cable so that I can plug them in the adapters:
Plugging them was straightforward and they are tightly attached:
This is a part where these don’t work well with my ears and the KZ ZS7.
This adapter is supposed to be hanged behind the ears:
Unfortunately, My KZ ZS7 doesn’t get sealed in my ear and the TRN BT20 pushes them out, so I’m using them without hanging them behind my ears:
They are not heavy and now my KZ ZS7 seals fine in my ears. I think if TRN releases a version of the BT20 with a larger ear hook, then they may fit better. Otherwise, I don’t have a problem using them this way.
Pairing the TRN BT20 with my phone was extremely easy. You just turn it on and it will enter in pairing mode automatically. From there, you can choose it in your phone and it will pair:
I haven’t yet discharged the TRN BT20 battery entirely, as I don’t listen to music at loud volumes. My Android phone reports 50% of battery left after about 3 hours of continuous usage. The volume is set around 1/4 of the slider and that produces a comfortable audio level to my liking. Past it, and it’s too loud. As mentioned above, the TRN BT20 supports the AAC audio codec which my phone is using. Because of this, charging normally takes around 45 minutes (Remember I have not discharged this completely). I’m not using the supplied cable to charge them. Rather, I’m using the UGREEN Micro USB Y cable:
There’s one side that will always charge faster because one side acts as a receiver while the other is receiving and transmitting the audio to the other BT20 side. I have paired the left adapter to my phone so that one takes a couple of more minutes to finish charging.
I’m actually surprised by the quality of these. I think, personally, that the TRN BT20 has an advantage given that it uses a Realtek SoC on both sides. This means each side is decoding its own audio channel. This is similar to how balanced DACs work, in that each DAC decodes a specific channel. This has the advantage of improving the sound stage and channel separation. That’s exactly what I’m experiencing with the TRN BT20. The tonality is just awesome.
Because each side is decoding their own corresponding audio channel, I feel this improves the sound separation much like how balanced DACs work, except that there are no cables around.
It’s true that the TRN BT20 doesn’t support aptX nor LDAC, but given its ability to decode AAC, the audio quality is of very good quality. Even using the SBC codec, I find the quality to be amazing.
There’s a bit of a hiss when used with sensitive IEM’s, but it’s way less than other Bluetooth adapters, especially those that are not using dedicated audio DAC’s in their implementations. The sound quality is not degraded because of this, but I’m sure some may not like the hissing.
Overall, I’m pleased with the sound quality, and I’m using this Bluetooth adapter rather than my USB DACs with their cables.
I’ve been using the TRN BT20 with my Samsung Galaxy S9+, where it uses the AAC audio codec. The sound quality is excellent.
I also tested this with my HiBy R3 and Hidizs AP80 which I use as a DAC and Bluetooth transmitter to transmit my PC audio to the BT20. In this case, the SBC codec is used, as Hiby OS does not support transmitting AAC audio yet, although HiBy replied to a comment saying they may add this in a future firmware.
I normally set the volume between 7 to 13. Going up, it is too loud.
The only problem I found is that when using some Qualcomm transmitters with Windows, the volume will be extremely loud.
At around $33-34 on Amazon, you can’t go wrong with the TRN BT20. They do not have aptX, but their ability to decode AAC means the audio quality is not compromised.
The use of Realtek on both sides means each side decodes their own channel audio, which can improve the sound separation and sound stage.
There’s a bit of hissing which could be distracting for some, but it’s not very noticeable compared to other adapters.
The battery life is great and will last some hours. Charging should take at maximum 2 hours, but it charges in way less than that, having a 70mAh battery on each side, and charging at about 50mAh, it should take about an hour and a few minutes.
Unfortunately, it’s the fitting that didn’t work for me, but this part is one that depends on the IEM’s being used and your ears.
I’d rate this 4 out of 5, that last star being because of it not playing nice with my ears.
You can get the TRN BT20 on Amazon. Select the version that is compatible with your IEMs:
Yesterday, I received the Tempotec Sonata iDSD Plus:
This is a DAC and AMP all in one device. It has Dual ES9018K2M, Dual ES9601K amplifiers, as well as a Balanced 2.5mm headphone jack as well as the regular 3.5mm jack.
The device is very similar to the Hidizs DH1000. In fact, it is a rebranded Tempotec product. Today, I’ll take a look at a newer Tempotec Sonata iDSD Plus revision.
The Tempotec unit I received should have some problems that the Hidizs DH1000 had. In particular, this unit should have the Blue LED problem fixed, where it would be permanently turned on at some point of the Hidizs DH1000 lifetime. I’ll also be comparing this version to the Hidizs DAC.
As seen in the picture above, the box look very similar. Let’s take the wrapping off:
Now, it’s time to open the box:
We find the Tempotec Sonata iDSD Plus inside the box. It is the first thing we see. Below the box, we find some more items:
We find a USB-A to Micro USB, a Micro USB to Micro USB OTG cable, and a USB-C to Micro USB cable. We also have the manual and other stuff.
Let’s take a look at the Sonata iDSD Plus:
It came well protected. The bag keeps the iDSD free from scratches, since it uses glass on both sides.
Not a single scratch in the bag. That’s great. Now, let’s take out our Sonata iDSD Plus:
This is the front. While we can’t see the charging LED, it is in the bottom left corner. It is blue, just like the Hidizs DH1000, and will turn on while charging. Also, on the upper left, we can see the volume buttons. We’ll see them later in details.
The back has the Tempotec branding, just like the Hidizs DH1000 also had the Hidizs branding.
The Tempotec Sonata iDSD Plus has 3 USB ports. The USB-A is the so called “Private” port. This allows you to connect your compatible DAPs like the Hidizs AP80 and HiBy R3 when the USB mode is set to “Dock”. It also should work on Android and iOS devices when using the HibyMusic app.
The other ports are Micro USB. The middle port is for data transmission while the right port is for charging. The Tempotec Sonata iDSD Plus charges at 5V/1A, usually drawing 800 mA but it can draw 940 mA if it is also turned on while listening to music and it is charging.
On the other side, we can see the standard 3.5mm audio jack on the left, the 2.5mm balanced jack in the middle, and the power button on the right. Between the power button and 2.5mm audio jack, we see the power LED, which will be green if it’s turned on, and will turn red when the battery is low.
Next, we’ll take a look at the cables:
Above, we have the USB-A to Micro USB cable. This is the cable that you’ll be using to use the Tempotec Sonata iDSD Plus in your computer, unless yours have a USB-C port, in which case you can use the included USB-C to Micro USB cable:
The USB-C to Micro USB cable also works with compatible Android devices. It works really well in my Samsung Galaxy S9+.
If your device has a Micro USB port, you’ll probably need this OTG cable, which is also included:
However, not all Micro USB phones support the OTG connection, so please be sure to check if your phone is compatible with USB Audio Class 2 audio devices.
The Tempotec Sonata iDSD Plus manual comes in 2 languages:
And in English.
It also came with the Hi-Res Audio stickers:
Here’s how it looks when it has both USB ports plugged in:
Comparison with the Hidizs DH1000
Let’s compare the device with the Hidizs DH1000. Please note that due to hardware problems, I tried to repair the Hidizs DH1000, and while it works, I have it covered differently than how it used to look.
We can see they look similar.
The back also look similar. However, here is where we’ll see the main difference:
The Hidizs DH1000 has the volume buttons marked with paint, while the Tempotec iDSD Plus has the actual marks deep in the buttons.
Finally, both the USB ports and audio jacks look the same:
The device is detected on Windows a USB HD AUDIO as soon as it is plugged in.
The sound quality of the Tempotec Sonata iDSD Plus is the same as the Hidizs DH1000. I seem to find it more pleasant, but I tried switching between the Hidizs and Tempotec to see if I could find any difference. I may prefer the Tempotec sound, but the Hidizs one sounds quite similar, if not, identical. They both use the same ES9018K2M chips and ES9601K amplifiers. Theoretically, even the printed circuit board should be the same, or almost identical, except for the charging circuit, where it should be different to prevent possible charging issues.
I’m using the KZ ZS7 IEMs with a 2.5mm balanced cable. The bass feels powerful. This is especially true when listening to Twenty One Pilots “Trench” album. The mids are balanced, vocals are very well presented, and the treble, that’s the part where this DAC shines. The frequency response, I would say, is neutral. Other DACs would prefer to focus on providing forward vocals, and other instruments would sound recessed, but this is not the case with this DAC. Instrument separation is also pretty good. The sound feels open and wide, and the overal sound presentation is just as good and even relaxing. I can confortably listen to music in Tidal and enjoy every note in the song.
For around $130, this DAC does not dissapoint. The Hidizs DH1000 was my favorite, but now I have this Tempotec which will be with me at all times, and I’ll be attaching it to my HiBy R3 and Hidizs AP80 DAPs. Really, I haven’t found a DAC that outperforms this one.
This is a cable (or dongle) that allows you to connect your 3.5mm headphones to your devices that have a USB-C connector, or to a USB-A connector by using a USB-C to USB-A adapter. It features a sample rate of up to 24-bit and 192khz, but you’ll need to update the firmware to be able to use it. We’ll see more about the firmware update process later. First, let’s proceed with the unboxing.
Opening the box reveals a carrying case:
Taking it out we can clearly see the Hidizs logo in it:
The back is just plain:
Inside, we can see the Sonata HD Cable and a USB-C to USB-A adapter:
A closer look at the cable and adapter inside the carrying case:
A closer look at the DAC We can see the Hidizs Logo at the USB-C connector side:
We can also see the Hi-Res Audio logo on the other side at the USB-C connector:
Side by Side comparon with the Google and Apple DACs:
Now, let’s see the USB-C to USB-A adapter closer:
I connected the cable to the adapter and to my USB Hub which is connected to my desktop PC:
Sonata HD A: Prioritizes the Call. When I tested this firmware, it allows simultaneous voice and music. This is the firmware you’ll want to use if you’re going to stream on YouTube, Twitch, etc.
Sonata HD C: Prioritizes the Audio. When I tested this firmware, it was similar to the Sonata HD A firmware but I could no longer use the microphone as soon as the system produced audio. This firmware has a sample rate of 24-bit/192khz
Sonata HD D: Pure Music. This firmware will also provide 24-bit/192khz but it will disable the adapter input function. You’ll still be able to use earphone inline remote control.
To update the firmware, you’ll want to launch the respective executable. You’ll be presented with the firmware flashing utility:
We should write in the Vendor ID: 22e1, and on the Product ID: e202. You can check these values by going to the Device Manager and selecting the Sonata HD Cable under the Sound, video and Game Controllers section:
We can press the Write EEPROM button on the firmware flashing utility and we’ll be shown with this message:
We’ll simply disconnect the DAC, connect it again, and press OK. The firmware flashing will begin:
If it finishes successful, you’ll see a successful message:
That’s it! We now need to unplug it and connect it again and then we can go to the sound settings and check that we can choose a sample rate of 24-bit/192khz:
We click on Sound Control Panel and double click on the Sonata HD:
Now, we can go to the Advanced tab and select 24-bit/192khz:
We can also use Tidal’s WASAPI mode with this adapter. Just be sure to turn the volume very low. This DAC is very loud!!!
Just select the Exclusive Mode button and that should be it. Now, you can enjoy your music!
Listening to this DAC the sound is detailed, but the vocals seems to be more forward. It has a good sound separation, and it is very loud, which is why I have my DAC at just 2%. My headphones (KZ ZS7) are high sensitivity, low impedance IEM’s, so they will sound loud at low volume levels. The Bass is great, and so is the treble. No complains here. I also own the Hidizs DH1000 and their AP80 player and they all sound excellent. The Hidizs DH1000 provides a more neutral sound and the AP80 just shines at all of the frequencies, altough the DH1000 is still a more neutral and extended treble option.
I hope you liked this post. Do you own the Sonata HD Cable? Let me know in the comments.
If you don’t yet have this dongle, you can get it on Amazon using the following link:
Unboxing the Revonext 3.5mm with 3 buttons and mic to 2-pin 0.78mm IEM cable
Today, I’m sharing my Unboxing video of the Yinyoo 2.5mm Balanced to 2-pin IEM In-Ear Monitor cable. This is a 2.5mm balanced to 2-pin 0.78mm cable that is compatible with IEM’s like the KZ ZS7 which I have. In this video, I’ll also be testing the cable with my HiBy R3:
Do you have this cable or another one? What do you think of it? Let me know your cable recommendations below.
