1 / 8Razer has long been a fixture in affordable gaming peripherals, but the latest earbuds are... different.
A 2.5 puts its noise isolation / ANC in the bottom quarter of wireless earbuds we've measured.
Measured on 133 of the 271 we've cataloged.
below average for wireless earbuds — based on 243 of 271 we've cataloged.
below average for wireless earbuds — based on 245 of 271 we've cataloged.
IPX4 is the most common — on 33% of the 244 wireless earbuds we've cataloged (of 271).
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.

Measured frequency response (dB) against the SoundGuys house target — the dashed curve. The closer the measured line tracks the target, the more neutral the tuning; peaks ride above the target, dips fall below it.
