The Corsair HS70 is a wireless headset which features virtual 7.1 surround sound using 50mm drivers in a closed back design. The headset connects to your PC using an included USB dongle and utilises a 2.4GHz low latency wireless connection.
Additional features of the headset include on ear controls, a detachable microphone and an advertised battery life of 16 hours (although my experience was closer to 12 hours), all of which makes the HS70 a very alluring offer at a retail, price of approximately $100.
The headset is extremely comfortable and the build quality is good. Sound quality is also exceptionally good for a wireless headset, and this is from someone who normally avoids wireless headsets and uses professional grade wired studio headphones that cost about 6 times more than the HS70. The microphone quality is also good and delivers crisp and clear quality sound.
In closing, the Corsair HS70 is a great wireless headset at a great price.
