Unboxing the KZ AS16 In-Ear Monitor

Unboxing the KZ AS16 In-Ear Monitor

Hi everyone,

Today, I’m sharing my unboxing video of the KZ AS16 In-Ear Monitor. This IEM has 8 balanced armatures per side, for a total of 16. In the video, I compare the size of it with the KZ ZS10 Pro, which is also another of their newer IEM.

I’m currently listening to the KZ AS16 and will soon give my impressions of it. In the meantime, here’s the unboxing video:

Hi everyone,

Today, I’m sharing my Unboxing video of the KZ ZS7 IEM. These have become my new favorite IEM to use to listen to music. They have a really good sound reproduction. Watch the video below:

Do you have these IEMs? What do you think?

Unboxing the Google USB-C to 3.5mm Headset adapter

Hi everyone,

Today, I’ll be sharing with you my unboxing video of the Google USB-C to 3.5mm Headset adapter.

This is a USB-C adapter that allows you to use headphones, earbuds, IEM’s and headsets with compatible devices like Android phones supporting USB Audio devices or with a PC, in which this dongle is detected as “Headset Adapter”. It features an integrated DAC (Digital-Analog Converter) although it is unknown which DAC it uses.

The reason I got this adapter is to use my headphones with integrated mic with my PC. It has a maximum sample rate of 24-bit / 48Khz and it even let me use the headset buttons to change volume and to play/pause music with my favorite music player!

Here’s the unboxing video. I hope you all enjoy it:

Hi everyone,

Today, I’ll show you the Hidizs EX-01 in-ear headphone:

We can see it has a frequency response of 20-20K. Also we can see that the driver size is 8mm.

I haven’t taken the wrapping of it, so here’s the pictures with the wrap taken off:

When I opened it, we can see some promotion material:

And then we can see the headphones itself:

When we take them out, this is how it looks:

Sound

How does it sounds? For me, it, focuses on bass and mid bass, therefore, the sound will be bassy, but not boomy enough to distort the audio. Treble is also there, but is not extended. The voices sounds a bit bassy too, but they are clear, which means Hidizs did a great job with the tuning to not distort it. Since the focus seems to be on bass, the mids and treble seems to be a bit recessed. Sound stage seems wide, but you’ll be hearing more bass than any other instruments. Even when these may have a bassy sound, it’s still clear and you can still enjoy your music.

If you’d like an In-Ear headphone focused on bass, these may be for you.

Hidizs also offers the EP-03 and the Seeds earphones which I do no have yet to compare.

Hidizs also makes DAPs (Digital Audio Players) and DACs (Digital-Analog Converters). I have the Hidizs DH1000 DAC which provides a very natural sound and an enjoyable sound, and the Hidizs AP80, which also sounds awesome.

Hidizs is known for making high quality audio devices.

Unboxing of the Cave UC3 3D Surround Earbuds

Unboxing of the Cave UC3 3D Surround Earbuds

Hi everyone,

Today, I’d like to show you the Cave UC3 3D Surround Earbuds, which I got as part of their Kickstarter campaign.

These are a USB-C or Apple Lightning Earbuds, depending on the version you get, and is compatible with USB-C devices that support USB Audio and of course, Apple devices if you chose the Lightning version. It has an in-line control and microphone. The in-line control allows you to change the audio sound profile, enabling their virtual surround function.

Let’s get started with the photos!

Here’s the box:

Finally, here’s the earbuds taken out of the box:

Now, some notes:

  1. When I connected these earbuds to my Windows laptop via it’s USB-C port, it worked, but the volume doesn’t work. If it’s between 1 to 99%, the volume will be very low. When it’s at 100%, it will be very loud. There’s no way to control this except from the music app itself. This is unconvenient.
  2. When I used this with my Hiby R3, it worked. However, it only worked with 16-bit/48Khz audio. This is because the earbuds doesn’t have a 16-bit/44Khz mode. My best guess is that the Hiby R3 changes the USB mode to match the audio bit depth and sample rate. When I played back 44Khz FLAC files, It was showing a playback error. When I played back Opus files, it worked, but Opus files are 48Khz, which is why I think it worked.
  3. They worked great with my smartphone. However, they note that the microphone may not work with all smartphones. Keep this in mind.

In conclusion, I’ll keep these safely stored. They will not be my daily use earbuds, but rather I’ll use it for emergency purposes shall my in-ear earbud give me problems.

Unboxing and Overview of the Symphonized Hybrid Wireless/Wired High-Performance Headphones

Unboxing and Overview of the Symphonized Hybrid Wireless/Wired High-Performance Headphones

Hi everyone,

In this post, I’ll unbox the Symphonized Hybrid Wireless/Wired High-

Performance Headphones and give you an overview of the product.

Symphonized Hybrid - 1

As the name says, these headphones are hybrid, meaning they work either by Bluetooth connection or wired by connecting them with supplied AUX to MicroUSB cable.

Usually, you’ll find the ability to use the headphones either by Bluetooth or Wired in Over-The-Ear headphones, but not on In-Ear headphones. These ones do just that, so if the battery dies, or you prefer to listen to your music wired, then these headphones are perfect for you.

The Headphones with no cables attached

These headphones were part of a Kickstarter campaign, and the shipping of it was pretty fast. Delivery was done in just 3 days!

The battery is stated to last 5 to 6 hours when continuously listening to music. I’m still testing them, as yesterday I started using them before charging them and then I started listening to music via the wired cable. Today, I started the day listening via Bluetooth.

Some things I’ve noticed of the headphones so far:

  1. The headphones MUST be turned off in order to use Wired-Mode. Otherwise, they make some noises.
  2. When charging, it also makes some noises if you turn them on.
  3. I believe this is because Symphonized decided to use the USB Data Lines as AUX Left/Right channel connections, so when you plug this into a computer to charge, it makes some noises, maybe due to “data transmission”.
  4. The AUX to Micro USB cable is only for listening to audio/music. The mic and control buttons will not work when using the headphones in wired mode.
  5. However, the concept is really good, and the sound is pretty awesome as well.

About the sound quality…

The box says the frequency response is 200Hz-8Khz. I’m assuming this is a typo, because the sound is very good, actually. You can hear everything from bass to mids to treble.

Symphonized Hybrid - 5

The headphones also make use of the APTX Audio Codec. I tested this by using my Avantree Leaf USB adapter, which, depending on the Audio Codec used, the adapter’s light either is blue, or orange, and flashes either one or two times. When it flashes orange one time, it means it is using APTX codec. If it’s orange and flashes two times, it is using APTX Low Latency codec. Thanks to that, I can prove it is using the plain APTX codec, so there’s no support for APT Low Latency, but the latency is not very noticeable, however.

These headphones make use of a CSR chipset. Specifically, the CSR8645 chip. CSR was acquired by Qualcomm in 2015, and they make quality Bluetooth chipsets. Because these headphones use a CSR chipset, you can expect spectacular audio quality, especially when paired with an APTX-enabled device.

Showing the sides of the box:

Overall, I’m enjoying these headphones a lot.

That moment when your headphones/earphones are getting bad…

That moment when your headphones/earphones are getting bad…

Hi everyone,

Today, I’ll tell you something that happened with my music listening experience.

I am a music fan, and I have lots of Music CDs I get on Amazon and eBay. My music collection is uploaded to Google Music and some of the CDs are stored on Amazon as part of their AutoRip program. I also pay the monthly Amazon Music Unlimited subscription, and when I like an album, I buy it (Support the artists 😁):

My music collection

So, for the past few days, I’ve been streaming my music from Amazon like I normally do, but I noticed that the quality had changed. I went to the settings to double check the Best Quality settings was checked, and it indeed was. I then proceeded to Clear Cache, but I didn’t noticed any quality improvement.

Headphones going bad - 2

Ok, so I was using my Avantree Clipper Pro Bluetooth Adapter with my JBL Synchros S200 Earphones, so I plugged it directly to the phone, but the quality improvement was minimal.

Today, I connected my Avantree Leaf USB Bluetooth Adapter to my laptop so that I can listen to music with my Avantree Clipper Pro using the aptX Low Latency Codec and I noticed the same quality issue. I then opened Google Music, to compare the quality of some of the tracks, and while in Google Music, they sounded better, as the files are MP3 320kb compared to Amazon’s 256kb, it wasn’t that much of an improvement.

I did notice something odd, that it seemed the music was being streamed almost in mono instead of stereo, so I came to the least expected step: Test the headphones using the Windows Sound management window:

Headphones going bad - 3

Surprisingly, it wasn’t me, nor the adapters or sound card, but the headphones itself. It seems it’s mixing both channels, as while the sound remained Stereo, it was sounding more on the other channel than it’s supposed to be, like it’s mono and stereo at the same time 😂.

So, it’s the moment to say, R.I.P. JBL Synchros S200, which were my favorite earphones for these years and unfortunately JBL discontinued it:

What earphones am I using right now? Well, I still had the earbuds that came bundled with my Samsung Galaxy Note Edge, so I’m using that along with the Avantree Clipper Pro adapter to turn them wireless:

These earbuds sounds nice, being honest, and I was keeping them as a backup in case the JBL failed. That was also my second JBL pair as the first also went bad after the year.

So, now I can continue listening to Journey to the PastOnce Upon a December and At The Beginning from the Anastasia Motion Picture Soundtrack 😁:

I love Soundtracks!

[4K Videos] Unboxing Dollar Tree $1 Headphones

Hi everyone,

In today’s post, I will be sharing with you some unboxing videos of some of the Headphones available in Dollar Tree for just $1 dollar + tax. How do these extremely cheap headphones sound? Awful. They should only be bought if you really don’t care about sound quality or it is just temporarily while you get higher quality in-ear headphones.

Here are the unboxing videos:

Do you have a cheap in-ear headphone pair that actually sounds good? Let me know in the comments.
