INTRODUCTION

   Wireless gaming headsets may already count well over a decade in the market but it wasn't until 2018 that consumer demand showed a significant increase and that seems to be the case ever since. Two things were primarily responsible for this, the introduction of numerous high-end models by most of the popular manufacturers and of course the integration of several rather recent technological advancements in this particular industry which offered impressive boosts in battery life, lag-free audio, signal quality (range) and of course higher audio fidelity. From all the wireless headsets released in 2019 and 2020 however only a handful stand out from the rest, the GSP 670 by EPOS Sennheiser is without doubt among them and it's also the focus of today's review.

   Just like in the case of the GSP 370 model (review here) the GSP 670 is a closed type 7.1 virtual surround sound wireless gaming headset which is based on two 50mm neodymium dynamic stereo drivers that feature a very wide frequency response of 10Hz–23.000Hz with 112dB sensitivity. A similar noise-cancelling unidirectional boom microphone is also present here but with a far wider frequency response of 10Hz–7.3KHz with -47 dB sensitivity. Aside its rather impressive specifications however the GSP 670 also features Bluetooth connectivity (compatible with the AAC/aptX/aptX Low Latency audio codecs), two adjustable tension sliders, lift to mute microphone function, earcup volume wheel, split padded headband, memory foam ear pads, low-latency wireless connection with lag-free audio (thanks to the 2.4GHz RF USB dongle - wired use is also possible), simultaneous 2.4GHz and Bluetooth connection (2.4GHz overrides Bluetooth when not in a call) and a rechargeable lithium-ion battery pack which can provide the headset with up to 16 hours of playback (20 using the Bluetooth connection - this is honestly the only thing that the GSP 370 did better). So, let's get close and personal with the older brother of the GSP 370, the GSP 670.
