Summary: If you want a quality Bluetooth headset that can be either mono or stereo, then the Plantronics Voyager 855 is an excellent choice.
Pros: The Plantronics Voyager 855 is a sleek and sexy Bluetooth headset that can be converted from mono to stereo via an earbud cable. It has a sliding boom mic, a comfortable fit, plus excellent performance. It is also very lightweight.
Cons: The Plantronics Voyager 855 has tiny controls on the side, and the act of sliding the boom mic up and down resulted in a slightly insecure fit. It's also a little on the expensive side.
Summary: Although it acts as a dual-function device, the Voyager 855 is best suited as a regular Bluetooth headset, providing excellent in-call audio quality. The detachable earpiece is a nice idea, but the small buttons and average sound quality diminish its appeal.
Pros: Stylish design, comfortable to wear for long periods, excellent incoming and outgoing audio for voice calls
Cons: Sliding microphone open makes the headset feel loose, poor audio quality for music, small controls
Summary: Omdöme: Genomtänkt med en löstagbar stereokabel som enkelt kopplas samman med mikrofonbommen. Ingen ljudsensation vid musiklyssning, men tillräckligt om man inte har extrema krav. Trevlig design, men inte lika sober som Invisio G5. Bra lyssningsljud, men mottagarna klagar på burkigt ljud.
