Using the KZ aptX HD Bluetooth Cable and the TRN BT20 with the Hidizs Mermaid MS1/MS4

Using the KZ aptX HD Bluetooth Cable and the TRN BT20 with the Hidizs Mermaid MS1/MS4

Hi everyone,

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:

You can get these Bluetooth items as well as the IEMs using the following links:

Hi everyone,

Today, I’ll be reviewing the TRN BT20 Bluetooth adapter for 2-pin In-Ear Monitors (IEM):

TRN BT20 1
TRN BT20 1

The TRN BT20 is a Bluetooth 5.0 adapter that is available in 3 different versions:

  • 2-pin 0.75mm
  • 2-pin 0.78mm
  • MMCX

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:

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.

TRN BT20 12
TRN BT20 12

I removed the IEM from the cable so that I can plug them in the adapters:

TRN BT20 13
TRN BT20 13

Plugging them was straightforward and they are tightly attached:

TRN BT20 14
TRN BT20 14


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:

TRN BT20 15
TRN BT20 15

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:

TRN BT20 20
TRN BT20 20

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.

Audio Quality

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.

TRN BT20 AAC codec

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.

TRN BT20 21
Hidizs AP80 using in DAC mode and transmitting audio via Bluetooth

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:

The Genki Bluetooth Adapter for Nintendo Switch

The Genki Bluetooth Adapter for Nintendo Switch

Today, I’d like to show you the Genki Bluetooth Adapter specifically made for the Nintendo Switch. This was a Kickstarter Project that ran successfully. The Genki Bluetooth adapter is basically a USB-C Audio Device that converts the audio signal into Bluetooth and transmits it to your favorite headphones or Bluetooth receivers. Given that this is basically a USB-C adapter, this means that it is also compatible with PC’s and certain Android devices supporting USB-C audio devices.

Since the Nintendo Switch doesn’t currently allow the connection of Bluetooth audio devices, this comes very handy, as the latest Switch firmware adds support for USB Audio Devices. This adapter does its magic because it has a chip that converts the audio that the Switch transmits to this device into Bluetooth and therefore enables you to use your Bluetooth devices with your switch. It also has the benefit of using Qualcomm’s aptX and aptX Low Latency codecs, the latter which is a most to play without any noticeable audio lag. It also supports the AAC codec and of course, the standard SBC codec.

As to why you’d like to use this device on your Android phone or PC, there are several reasons. The first is that all of the pairings is done on the device, which means you don’t have to play with your phone or PC bluetooth settings, and the second reason is the inclusion of the aptX Low Latency codec, which, if you have an aptX Low Latency receiving device, you’ll be able to game or watch a video without any lip-sync or gaming audio issues.

I, as a backer of interesting products, backed this device and I’ll be showing this to you. Let’s start!

The first thing you’ll notice is how it comes packaged. It looks like if it’s a Nintendo Switch game:

Genki 1

You can see more details of the Genki on the back of the case:

Genki 2

Opening it has a familiar look to a real game case, but of course, the right side is adapted to hold the adapter along with the accessories:

Genki 3

On the left, you see the instructions of how to use this little device:

Genki 4

On the right, it’s the adapter and the accessories, similar to how you’ll find a Nintendo Switch game cart on this side:

Genki 5

The Genki adapter is very small, as you can see here:

Genki 6

It also comes with this Microphone to use it on compatible games:

Genki 7

And of course, you’re most interested in seeing this connected to the Nintendo Switch, so here it is!

Genki 8

And if you want to use the adapter in a PC, you’ll need a USB-A to USB-C adapter, and it would look like this:

Genki 9

Finally, Windows will recognize this as an Audio device, as you can see:

Genki 10

Now you can enjoy wireless audio with your USB-C devices, especially on your Switch!

Hope you enjoyed the photos!

Unboxing the Google USB-C to 3.5mm Headset adapter

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:

The JET-5608AK DDR4 SODIMM to DIMM Adapter

The JET-5608AK DDR4 SODIMM to DIMM Adapter

Hi everyone,

Some time ago, I purchased the JET-5608AK SODIMM to DIMM Adapter. What this does is convert a SODIMM RAM module into a DIMM module. SODIMM is the RAM used on laptops, while DIMMs are the RAM used in Desktop computers.

JET-5608AK DDR4 SODIMM to DIMM Adapter - 1


The product came in a very simple box:

JET-5608AK DDR4 SODIMM to DIMM Adapter - 2

And opening it shows just the SODIMM to DIMM adapter very well protected:

JET-5608AK DDR4 SODIMM to DIMM Adapter - 3

The front of the device can be seen at the start of this posts but here it is again:

JET-5608AK DDR4 SODIMM to DIMM Adapter - 1

And the back of it:

JET-5608AK DDR4 SODIMM to DIMM Adapter - 4

Product usage:

I’m going to use this with an 8GB Samsung SODIMM DDR4 module from my laptop:

JET-5608AK DDR4 SODIMM to DIMM Adapter - 5

This is the front of it with the RAM inserted:

JET-5608AK DDR4 SODIMM to DIMM Adapter - 6

And the back:

JET-5608AK DDR4 SODIMM to DIMM Adapter - 7

Inserting the module in the machine:

I’m going to use this module with an ASUS B350M-A motherboard and an AMD Ryzen 7 1700 CPU. I currently have 32GB of RAM in it. Using this would raise it to 40GB as I’m using an 8GB Samsung DDR4 SODIMM module:

JET-5608AK DDR4 SODIMM to DIMM Adapter - 8

But because some machines have compatibility issues, I’m placing the RAM alone:

JET-5608AK DDR4 SODIMM to DIMM Adapter - 9


It didn’t work.

That’s right. This module is NOT compatible with this motherboard or CPU, it seems. Even when placed alone or with the other RAM modules, the machine refused to boot. This could very well be the BIOS or can be the CPU itself not supporting SODIMM modules. After all, this CPU was released before the mobile AMD Ryzen CPUs were released.

Some people have got this adapter to work on their machines. You can read one of such reviews in Newegg, and there is a Reddit discussion of it over here.

Anyway, the adapter is not expensive and it was worth getting it to see if it would actually work. It would have been nice to use spare DDR4 SODIMM modules with my desktop.

Hope you enjoyed reading this post and be sure to follow me for more tech stuff!

All photos were taken using a Samsung Galaxy S9+.

On Mute Heaset Microphone Muting Adapter

On Mute Heaset Microphone Muting Adapter

Hi everyone,

Today, I’ll share with you an unboxing video of the On Mute Headset Microphone Muting Adapter that I received for backing the project on Kickstarter.

The On Mute is an adapter where you connect your headset and allows you to easily mute the mic and use a Push-To-Talk button to enable the mic temporarily.

If you want to mute the mic, just move the switch to the Mute position and press the button to talk. If you want to allow the mic to work at all moments, just switch the mic to the Unmute position. Yup. It’s that easy to use!

This adapter is excellent for all of the people that are in Discord servers and participate in their audio channel sessions. You may have heard a moderator say to mute your mic or another member mic. Well, instead of working in Discord to mute your mic or change the Push-To-Talk setting, simply use this adapter!

So, behold, the unboxing video of the On Mute:

Hope you enjoyed this video!

Unboxing and overview of PLUB: Bluetooth Headphone Adapter

Unboxing and overview of PLUB: Bluetooth Headphone Adapter

Hi everyone,

In this post, I’ll show you a video of me unboxing the PLUB, which is a Bluetooth Headphone Adapter.

The Bluetooth adapter features Qualcomm aptX audio codec, so the audio quality is really good compared to the plain old SBC. The way you use this is simply by connecting a headphone/earphone to it.

The adapter also features no buttons except for the Reset one and that’s it. No power up, volume, or multi-function buttons are there. So you may wonder, how does it turn on?

The PLUB works entirely by using your headphone buttons. Just plug it in, and it will power on. Once it’s powered on, you use the headphone buttons to control your device. For example, to change the volume, you just press the headphone volume buttons as you normally would do. To play music, you just press the function button of the headphones. The PLUB effectively recognizes these signals and sends the commands to your devices.

There’s also no USB connection. Then, how do you charge it? Using the same 3.5mm jack! Yup, the PLUB comes with a USB to 3.5mm similar to how the iPod Shuffle would charge. Just plug the 3.5mm into the PLUB and connect the USB cable and let it charge. You can track the progress by checking the LED color.

Yesterday, I received the PLUB in the mail, and you guess what I first did: The Unboxing video.

You can watch it here:

Overall, I’m very satisfied with this device.

I’ll see if I make another video demonstrating how it works because it’s really a simple device and I really like it due to its simplicity.

Hope you enjoyed this video!

The PortaPow Data Blocker USB Adapter with Smart Charge

The PortaPow Data Blocker USB Adapter with Smart Charge

Hi everyone,

Today, I’ll show you the PortaPow Data Blocker USB Adapter with Smart Charge.

This is an adapter that, as the title says, blocks Data. This means that when you use this adapter in a PC USB Port, it will allow your tablet/phone to charge at the port maximum speed, overriding the 500mA USB limit. This is because when a PC detects a data connection, it negotiates the power with the controller. Some devices uses 100mA, like mouses and keyboards, and other more powerful stuff uses the full 500mA from the port. However, since this adapter blocks data between the device and the PC USB port, it doesn’t negotiates the power needed and as such, passes the full power the USB controller can supply.

The SmartCharge meaning in this device is because there is a controller that can check what device you have connected. There’s several charging standards like Samsung, Apple, and others. The adapter will detect that and because of this, allows fast charging for your device.

Please bear in mind that you must use a high quality USB cable or your device may not charge at full speed.

Let’s take a look at the adapter:

PortaPow Data Blocker USB Adapter with Smart Charge - 1

I purchased the 2-pack PortaPow Data Blocker on Amazon, so that’s why you see 2 adapters there.

Taking off the package contents, we can see again the 2 adapters plus a product overview sheet:

PortaPow Data Blocker USB Adapter with Smart Charge - 2

That sheet also has some important information, like that you need to use a high quality USB cable and that the USB port must be able to supply enough power, or your device may not charge at fast speeds:

PortaPow Data Blocker USB Adapter with Smart Charge - 3

A closer look at the adapters:

PortaPow Data Blocker USB Adapter with Smart Charge - 4

The USB Male connector:

PortaPow Data Blocker USB Adapter with Smart Charge - 5

The USB Female connector, where our USB cable will be connected:

PortaPow Data Blocker USB Adapter with Smart Charge - 6

Testing the adapter:

For this test, I’m using an Aukey Micro USB cable, which is of good quality. I’m also using my Lenovo laptop USB 3.0 port. The app being used in the phone is the Pro version of Galaxy Charging Current, which is an excellent app to measure how much power our device is consuming from the USB charger.

Here, I’m charging my Samsung phone by directly connecting it to the PC USB port. You can see that the power being drawn is 433mA because the PC detects there’s data and negotiates the power to 500mA:

PortaPow Data Blocker USB Adapter with Smart Charge - 7
PortaPow Data Blocker USB Adapter with Smart Charge - 8

However, when I plug the PortaPow Data Blocker, we can see it charges normally at 1200mA, or 1.2A. This is normal for this device when not using Qualcomm Quick Charge. The device is charging at 5V here:

PortaPow Data Blocker USB Adapter with Smart Charge - 9

See the difference between using the adapter and without it? Now our device charges faster and comes in handy when we can’t use our wall USB charger.

PortaPow Data Blocker USB Adapter with Smart Charge - 10

That’s it!

I definitely recommend this adapter. It is cheap too! The 2-pack costs only $12.99 on Amazon.

Get it here!
