Review: Gateway purchase to the next level of GSX... - 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.
Review: Read the reviews! - Like everyone points out, the EPOS program is a POS. The button to toggle presets or surround/7.1 sound doesn't work 90% of the time, the program crashes and freezes all the time, and it's generally clunky to play with. HOWEVER, the soundcard itself sounds great. The only issue I've had with it is that I'm using powered speakers instead of headphones so when you turn off the computer there is feedback. Luckily my speakers have their own power button, so I just turn those off along side the computer to solve that issue. Unfortunately in my experience the card doesn't work without the application so read the reviews and just be prepared to install a very poorly made software that requires you to sign up to the EPOS newsletter just to download it after already giving them your money for the device.

## Questions & Answers

**Q: Esta tarjeta de sonido es compatible con la Xbox series X?**
A: Hola y gracias por su pregunta. Lamentablemente, la tarjeta de sonido sólo es compatible con el PC. Espero que esto responda a su pregunta. Saludos cordiales del equipo de soporte de EPOS.

**Q: does this work without software?**
A: Hi there!

The GSX 300 does work without software (it will process the sound coming through it), however all the functionalities and benefits can be adjusted inside the software, so it wouldn't make sense not to download it. 

Please note, that the software and GSX 300 are only compatible with PC, so if you wish to buy the GSX 300 for a Mac/PS (where the software doesn't work), this is not possible, unfortunately. 

Regards,
EPOS

**Q: Will this fix the static sound my mic produces? i have the epos 602.**
A: This unit has mic volume issues as well. Wouldn't recommend it for microphone troubles. I've been dealing with their support unsuccessfully for software and mic issues.

**Q: Will this work with the sennheiser pc 373d - 7.1 surround sound gaming headset?. the headset is 50 impedance. what benefit would i get with this unit?**
A: Consider this an upgrade to your model's stock USB surround sound card/dongle. We're not talking about audiophile headphones that won't run straight out a motherboard's soundcard. This is the perfect for you.
