Do Not Buy the Sennheiser GSX 300
I do not recommend buying the GSX 300 until Sennheiser sort the mic and speaker levels out. On 100% the mic levels are very low. You can hardly see them on Audacity. The speakers are also very quiet. You will need to run them at 100% all the time. In summary, do not buy this item.

Just put an LED in it and slap "Gaming" branding on it.
It's a decent DAC and the presets are fine but there's a real lack of understanding of the audience that they're supposedly marketing this to. It has 2 inputs, Audio and Mic jack - pretty standard. As a gamer, you'll probably using a gaming headset. The vast majority of these are USB. The ones that aren't are typically a dual audio/mic on a single jack that plug into a sound card, usually included with the headset. And as far as standalone microphones go for the budding streamer/content creator, they're basically all USB these days; it just makes sense - digital content for a digital era. So the inputs themselves are useless; you'll utilise one at best for speaker input and essentially get no use out of the mic input as they're all USB or combined on the audio jack. It supports basically nothing a modern "gamer" would use in terms of hardware, and I get it, it would be relatively pointless to have USB inputs to a soundcard like this. But, it just proves the lack of awareness for the target audience and is just another piece of rubbish with no USP, so they stick some LEDs on it, give it a couple of colourways and say it's "gaming". I'd like to think somebody in the broad spectrum of what could be a "gaming" or PC "power-user" could find use out of this, but it's just not fit for purpose anyone. Casual gamer, upcoming streamer, podcast creator, music producer, game developer, pro gamer. Just so many better options.

1号の基盤がズレてしまい再購入。 1号は黒でしたが、2号は白にしました。 可愛いし、1号で音の出方もわかっていたので再購入しました。 安いのに凄い良いです。最高

This is an unusual gadgetry targeted at gamers but I find this to be indispensable for anyone with an ear for details and looking for sound quality in terms of enhancement of resolution. It just crystallizes the sound source and opens up the soundstage instead of filling it with echoes which other “virtual 7.1 sound cards” do. So “sheerness” is a five star- I would give a bonus star if I could, given the price point you will only be able to get soundcards that makes everything you hear blurrier and more “echowy”. One thing I disliked is the requirement for the installation of standalone software (even if it comes with equalizer function) that just gets in the way of being an external hardware completely, which is what it appears and was marketed to be. Volume control was somewhat N/A for me as I used volume knob on my keyboard to control instead of the GSX300 knob. After having a satisfying experience with both music and games, I cannot help but recommend with some reservation that this purchase will only embolden you to buy the GSX1000, which does not require software installation on your computer to function, and gives you an extra (I think 30% more) “sheerness”. Don’t get me wrong, you won’t regret this purchase if the inconveniences I described does not apply to you. It is an unbeatable performance at this price range. I recommend you get this and spend more money on getting a proper openback headphone with a good soundstage. Just remember you are stepping into audiophile territory when you deal with openback headphones, and this sound card cannot drive anything higher than 100 ohm in impedance.

external soundcard is detected by Windows, however the EPOS GAMING Suite says it is not detected. Tried following their workaround fix but still no avail.

Pros: good build quality, simple design, aesthetically pleasing on the desk, sounds quality ok for the price but warm setting on the mic is a nice touch Cons: really really low volume, didn't expect that my kraken is louder without it. if that smart button can be mapped to other things it would be a plus Edit: after reinstalling the software and a bit of tuning it works as expected thus this edit change from 2 star to 4 star
