Review: EC Technology USB External Sound Adapter

If you predominantly use a laptop as your daily workhorse, you too might only have the 4 pole 3.5mm headset socket on your laptop. You know the same one we get with smartphones and tablets. It’s nice as it means there is only port, which looks visual pleasing but it can become a bit of a pain. This is where the USB External Sound Adapter comes in. Read on for my review of it.

First of all I would like to thank EC Technology for the sample.

This device simply takes your 3.5mm microphone and 3.5mm headphones and converts them to a traditional USB connector. All you need is to plug in everything, wait for it to setup, and it will all magically appear. Go into your audio settings and select USB audio in your playback options as well as your recording devices. Boom everything then just works.


As far as an unboxing goes there isn’t much to come by. When you open the box you’re greeted with the adapter itself. Removing the little holder that houses the device, reveals a multi language quick guide. That’s your lot.

Coming in at 42mm long, 30mm wide and 10mm deep it is fair to say that this is a very compact device. It’s the perfect size for a travel kit to give you more options when out and about.

So if you listen to the podcasts (Episode 1, 2, 3, 4 ) you will notice that my audio was sounding pretty bad during the recordings. It was usable but it still wasn’t that great, especially for those having to listen it on the Podcast. So some time prior to Episode 6 of the podcast I procured this, and used it during that recording, and in that episode the audio was a lot better – noticeably better. If you haven’t got time to listen through the podcasts you can listen to the audio sample below. The first sample is using the in built mic on my laptop and the second sample is through a lav mic that cost me £1.98 (Check it out on Amazon) plugged into the adapter.

You can also use it with you smartphone with the simple use of an OTG cable. Giving you improved audio on your phone. Great for those quick interviews. These are also fairly cheap at about £2 for a good one. I tried this with my HTC One M8 as well as my HTC One M7 (as pictured below) and it worked great on both devices.

Most of you should know what an OTG cable is but for those you who do not, it is simply a cable with micro USB connector on one end and a normal female USB plug on the other. Allowing you to connect almost anything to your phone that uses a USB cable such as:

  • Mouse
  • Keyboard
  • Headset
  • Mic
  • Flash Drive

As you can tell overall the audio is greatly improved. Not only does it sound louder it also sounds clearer.

So to summarize if you have a laptop with a 3.5mm 4 pole combo port and you want to use a 3.5mm headphones and a 3.5mm mic at the same time it works very well, or if your 3.5mm ports start playing up or straight up die this is a great way of bringing your audio back without breaking the bank, especially as it only costs £10.

So would I buy this?

Well yes like I say I tested this with a mic that cost £1.98 and it sounds fairly crispy. Who doesn’t like crispy audio? Especially if it is cheap crispy audio. The fact that it can be thrown in a bag makes it a piece of useful tech.

Once again thanks to EC Technology for sending over a sample.
