Questions about this item

How does the 20 Hz – 40 kHz frequency response sound in actual games?

The wide range reproduces deep explosions and high-frequency cues like footsteps, while the 40 mm Hi-Res drivers keep detail clear across the spectrum.

What does Bluetooth 5.2 cap in practice for this headset?

Bluetooth 5.2 provides stable wireless audio to phones and tablets, while the 2.4 GHz USB-C dongle delivers lower-latency performance for PC and PlayStation.

Memory-foam leatherette pads distribute the 2.0 lb weight evenly, and the adjustable headband accommodates different head sizes for extended wear.
