Our Take

Best for: PC gamers needing affordable audio upgrade.

The EPOS GSX 300 is a capable external sound card that punches above its price tag. 1 surround sound that adds spatial awareness in games, and the microphone input is notably clean with adjustable noise reduction. The compact design fits easily on any desk and runs off USB power, so no extra cables. It doesn't include a powerful headphone amp, so high-impedance headphones may sound quiet, but for most gaming headsets the volume is adequate. The EPOS Gaming Suite software offers equalizer and surround controls, though it can occasionally feel clunky. At this price, the GSX 300 is a no-brainer for anyone wanting to upgrade from onboard audio without spending a lot.

Price Analysis

The EPOS GSX 300 is currently $24.99, a 69% discount from the $79.99 list price. Historical lows hover around $20-25, so this is effectively the best price you'll find. It's an excellent time to buy for a significant audio upgrade on a budget.
