Sennheiser SP 20 Mobile Speaker Phone - Clear Conference Sound

In this review of the Sennheiser SP 20 the bottom line is simple: it is a compact, reliable speakerphone for business professionals who need clear voice conferencing on PC, mobile phone or tablet. The SP 20 stands out for consistently natural voice clarity and echo cancelling, making small-group calls feel less strained. Its slim profile, plug-and-play USB/3.5 mm connectivity and long battery life mean it excels for impromptu meetings and mobile professionals who want a hassle-free conferencing tool without a lot of setup.

Key Features

• Unified Communications Ready: Optimized for major softphone and UC brands so professionals can join calls with consistent compatibility for PC and softphone use.
• Voice Clarity: Built-in echo cancelling and voice enhancement deliver clearer speech so participants understand each other with fewer repeats.
• Portable Design: Slim, lightweight profile and included carrying case make it easy to move between desks, meeting rooms or on the road.
• Extended Battery: Up to 20 hours of talk time keeps occasional all-day users connected without frequent recharging.
• Plug and Play Connectivity: A 3.5 mm and USB cable setup eliminates pairing steps so PCs, phones and tablets can connect quickly.
• Music Mode: A dedicated sound-enhancement profile provides better multimedia and music listening between calls.

Who It's For

The SP 20 is best for UC-focused professionals who need a portable, reliable speakerphone for one-on-one or small huddle meetings of up to about 6-8 people, and who value simple setup and strong voice performance. It is particularly useful for frequent remote workers or managers who split time between home, office and travel and use Skype for Business or similar softphone platforms.

Those who need full-room coverage for larger conference rooms or require deep integration with niche mobile apps should look elsewhere; some users report mixed compatibility with certain mobile calling apps, so buyers who rely solely on non-standard VoIP apps may require additional testing before committing.
