AOC 28" LED - U2879VF
gaming headset
Our top pick for gaming headsets remain with the following two headset: Kingston's HyperX Cloud Revolver, and SteelSeries' Siberia 350. Both headsets have stayed at the top in our charts for a while, and this tells us one thing: there are a plenty of mediocre headsets coming out because everyone wants in on the headset market. But only a handful are worth having. You won't go wrong with either choice.
It was a tossup between the Revolver and Siberia 350. Both are priced at just around $110 (£80), which puts them in the middle of the pack. Both have excellent sound quality that's suitable for gaming or music. And both are relatively comfortable. However, the Revolver is 100% analog, providing two 3.5mm cables (one for audio, one for mic), while the Siberia 350 is USB. The analog connection on the Revolver may make it more convenient if you're planning to use an external sound card or don't have any open USB ports. The Siberia's digital USB connection offers DTS simulated surround sound built into the headset as well as LED lighting that's controllable.
The two headsets are distinctly different in design, too, so you may prefer one or the other. That makes them our two top choices.
Measuring sound quality until now has been a subjective affair, which is why we went the extra mile in our testing. We used $50,000 of audio equipment to objectively quantify several aspects of a gaming headset that are crucial to sound quality: frequency response, distortion, and left/right balance.
What about lower priced options? There are headsets priced lower, even at half the price, but most don't perform well and cut too many corners to achieve their attractive prices. For around $100 or £77, the price is a sweet spot for performance. Going a bit higher yields very marginal to no improvements in sound quality or mic quality.
We're currently looking at new budget headsets from Kingston and SteelSeries, and new high-end options from AudioTechnica and Sennheiser, but the Cloud Revolver and Siberia 350 are still the best headsets for most gamers
