Product description

The ultimate headset for the working professional

The Sennheiser SC238 QD Mono is a monaural wired headset, optimized for users of narrow-band, high-impedance desk phones in contact centers and offices that require excellent sound performance and are engaged with their environment.

Extensive audio features

The SC238 headset is equipped with Sennheiser´s own Voice Clarity technology, allowing the user to be heard extremely well. The Noise Cancelling microphone gets rid of any undesirable background noise, whilst enhancing your voice.

All day comfort

Fitted with the CircleFlex dual-hinge ear cup, the SC238 is a pleasure to wear for everyday use. The ear cup is padded with a pleasantly soft leatherette, whilst the dual hinge feature allows you to adjust the headset to your exact preference.

Long-term reliability

The device´s rugged design, with its lightweight metal headband, ensures years of usage. Furthermore, the headset has been rigorously tested to adhere to call-center standards.

Be protected on the job

Sennheiser has ensured that the safety of the user is not compromised with the ActiveGard technology. This protects the user from dangers, such as acoustic shocks and very loud sounds on the line.
