Allowing you to instantly turn any space into a mobile meeting room, this is an ideal solution for professionals who need to make conference calls via various devices, whether in the workplace or on the move. 

Plug and play

The Sennheiser SP 20 ML plugs straight into any PC or Mac via its retractible USB cable, and into mobile phones or tablets via 3.5mm jack, allowing users to merge PC/softphone and mobile calls into one conference. Charging in just 2 hours via USB, talk time is an impressive 20 hours and battery status is displayed via LEDs with voice prompts for low battery warning.
