Powering up your 7.1-channel audio system will be a piece of cake with this reliable and quality-oriented adapter. Just hook it up to your PC, and it will start playing everything with clear audio. Whether it is music or movies, this adapter plays it all on your 7.1-channel system.

3. Epos Sennheiser GSX 300

Epos, the company formerly known as Sennheiser’s gaming division, has turned out something of a treat on its first attempt. The GSX 300 sound card is compact and relatively inexpensive at around £70, but it produces a great expanded sound stage and offers an immersive simulation of 7.1 surround sound on stereo headsets. High resolution sound is supported, up to 24-bit 96kHz, and the GSX 300 can drive headphones up to 75 ohms. That meant my 50-ohm Sennheiser HD 598 SE worked fine, but the 300-ohm HD 600 is off the table.

The small physical design means that there’s no room for additional ports – you just have Micro USB and two 3.5mm inputs for your headphones and mic – but it does mean that the GSX 300 is something you can easily put in your bag to use with a laptop on the go. A single to dual 3.5mm adapter is required if your headset uses a single TRRS jack instead of separate TRS connections for headphones and mic, but this isn’t a big issue as these adapters normally come standard with any headset that require them (not that they’re expensive anyway).

There’s a volume dial on the front, which offers tactile steps, as well as a second button that can be set to switch between sound modes or different EQ profiles. The software works well, with convenient EQ settings and comprehensive mic controls, but it did sometimes stop working and require a restart. This should have been fixed in a recent software update, and hasn’t occurred since in my testing.

If you want a compact USB sound card at a reasonable price, the GSX 300 is worth considering.

5. ASTRO Gaming MixAmp Pro

When it comes to audio, Xbox gamers often get the short end of the stick. Wireless headsets for the console are few and far between, and the original Xbox One console didn’t even have a 3.5-millimeter jack for plugging in your gaming headset. ASTRO clearly doesn’t want to leave Xbox owners hanging yet again!

This nifty audio solution is perfect for gamers looking to improve sound quality and voice communication within their favorite games. It features Dolby Digital Surround Sound processing and lets you quickly adjust game and voice balance so your friends’ voices don’t get drowned out by your intense game soundtrack.

How to choose the best external USB sound card in UK 2021

Picking the best external USB soud card won’t be easy unless you know what to go for. Here, we explain different factors to consider when choosing an external audio adapter.

Sound Quality

Probably the most crucial part: the sound quality lets you know how well the device will make your computer sound.

This is difficult to pick because all devices have different ways to deliver quality. But overall, going for a DAC system like Sound Blaster devices offer, as well as an amplifier feature will be enough to get perfect sound quality out of a USB audio device.


The number of output coming out of the device will make a huge difference in whether you can pair it up with your sound system or not.

Here, we recommend getting devices with as many ports as possible. We recommend at least 2.1 channels for Microphone and Headset/Speakers. But if you can go for models with 5.1 or 7.1 channels, that would be ideal.

This means going for devices with Rear, Front, Bass/Sub, Left, Right, Line-In, Line-Out, and S/PDIF outputs.


Want to tweak the audio coming out of the device to the max? Then choose something with as many controls as possible.

Usually, external sound cards come with their own volume wheel or knob. This is ideal for changing the volume handily from the device. But others offer the chance even to tweak the EQ system completely.

That will help you get the perfect audio delivery according to your demands. You won’t have any problem focusing the system on either bass, treble, direct, etc.


Finally, make sure the device is portable enough so you can carry it everywhere without problems. We recommend small sound cards that you can take everywhere without problems. But we also love those that have a long wire so you can place them far away from the PC for extra handiness.

Your whole focus should be on something that delivers practicality over everything else. As long as it fits your needs, then it won’t be a problem to enjoy what it offers.


Making your computer sound amazing is not hard when you have one of these devices. But still, you’ll have to pick the right one if you want the best possible experience.

But remember that the best external USB soud card is the one that matches your needs and desires; and nothing else. As long as the device you’re using goes well with what you need – then it will be an ideal option. Choose one now.
