Meticulously designed for maximum comfort and elegantly engineered for superior sound quality, loaded with unique features, the Pro HMD 300-XQ-2 headset coiled with the boom microphone offers input and output sounds that are incredibly detailed and crisp. The headset's closed-back over-ear design provides up to 32 dB of ambient noise attenuation, filtering out disturbances even in demanding environments. Your hearing gets an additional layer of Peak Level Protection with the Switchable Noise Protection mode (ActiveGard), which will protect your ears from excessive noise above 110 dB downwards and sudden bursts of sound without interrupting the signal. With its super-cardioid, dynamic design, the dynamic boom microphone offers a frequency response of 60 Hz-25 kHz, allowing it to produce a clear audio reproduction even in noisy environments.
