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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Smaller than expected lol *by D***S on 25 April 2022* The item works and looks great. Just way smaller in my hand than I thought lol ### ⭐⭐⭐⭐⭐ 3D surround sound *by M***L on 20 November 2022* 3D surround is excellent, I didn’t used product like this previously but sound of my GSP 500 EPOS headphone is greatly improved when 3D surround is on and for music its better that creative sound core 3d chipset on motherboard ### ⭐⭐⭐⭐⭐ Super *by J***N on 25 August 2023* Nachdem ich mir für meinen Laptop, Epos Kopfhörer gegönnt hatte, konnte dieser keinen Stereo-Klang erzeugen. Blöd wenn man nicht nachschaut ob der eigene Rechner das kann oder nicht. Mit der Externen habe ich jetzt wunderbaren Klang und möchte das Teil nicht mehr missen. Praktisch (für Mich) ist das wirklich lange Anschlusskabel, da am Kopfhörer selbst eher ein Kurzes verbaut ist. Jetzt kann ich auf meine Sessel rumlungern und Musik hören, anstatt auf dem Bürostuhl sitzen zu müssen. ## Frequently Bought Together - EPOS GSX 300 - External Computer Sound Card - High-Resolution Stereo & 7.1 Surround Sound - LED Volume Dial; Customizable Smart Button - Windows 10 Synchronized - beyerdynamic DT 990 Pro 250 ohm Over-Ear Studio Headphones For Mixing, Mastering, and Editing - EPOS Gaming B20 Streaming Microphone - 2.9m Cable USB-C Computer Microphone for Gaming - PC & Laptop Connection with Audio Controls - Compatible with PC, Mac, and PS4/5 - Desk Stand Included, Gray --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/254054196-i-sennheiser-gsx-300-gaming-dac-external-sound-card-7](https://www.desertcart.jp/products/254054196-i-sennheiser-gsx-300-gaming-dac-external-sound-card-7) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-31*
