## 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.
