Inside, the 40mm speakers cover the full range of sound (20Hz–20KHz) so you’ll hear both deep bass and crisp voices. With 105dB sensitivity, the ZRX-500 plays audio loud and clear without needing extra volume. The extra-long (about 6½ feet) gives you room to move around without being tethered too tightly to your device.

The boom microphone is built for voice accuracy, with -42 ±3dB sensitivity and a Φ6.0×5.0mm mic head, which simply means it’s tuned to pick up your speech clearly without all the background noise. Easy onboard controls make it simple to use: the S button pauses or plays your audio, while the M button lights up blue when your mic is on and red when muted. These headsets are built for wide compatibility, though button functions may vary slightly depending on the device.

Made from durable ABS plastic housing with reinforced PVC wiring, the ZRX-500 is built tough enough for everyday wear and tear — whether in a classroom, library, call center, or at home.
