Clear sound

great sound

Great sound and the Bluetooth makes this awesome for meetings.

The Jabra 510 MS provided an easy connection to PC and to IPhone, and all callers sound good - even around a conference table, and I sound good to them.

After trying multiple speaker phones with my PC, this one consistently has the best sound and others could hear me well.
