The verdict
The Razer Hammerhead Pro Hyperspeed has a lot of attractive features, but might not be enough to entice people to spend $200 on a set of gaming earbuds. Bargain hunters will be able to find better if they're willing to give up some of the more unique features of these earbuds.
✓Liked: Low latency dongle, RGB chroma lighting, Multiple EQ presets, Comfort
✕Could be better: Sound quality, Battery life, ANC is not the best
