Today we are reviewing not one, but two audio peripherals. First up is the EPOS | SENNHEISER GSP 602 headset, based on the highly successful Game Zero headset, which has an RRP of £199. We also look at the GSX 300 soundcard which is priced at £69. The GSP 602 is a wired-only headset that uses a 3.5mm jack, so it is “plug & play” with most devices, whereas the GSX 300 soundcard uses USB and only works with PC due to software requirements. Let’s see how they hold up against our testing.
