The Sennheiser SP 20 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.

Extensive testing has shown that its performance with Macs is far superior to equivalent speakerphones from other brands.
