Plantronics Mobile Convertible Headset M175C

Recipients of our phone calls reported no annoying disturbances or distortions during conversation, and audio quality on our end was clear as well, if a bit muffled. The headset works best on phones that feature good volume controls, because the microphone adjust switch raises and lowers the volume in a very narrow range.

The M175 also has the nifty feature of converting from a headband to an over-the-ear-style headset. Unfortunately, this also makes for a somewhat flimsy construction. Pieces immediately began falling off the unit as soon as we removed it from its packaging, though snapping the components back in place took little effort.

Overall, the Plantronics M175 headset is a versatile, quality headset for those looking for a hands-free way to work with their mobile or cordless phones. --John Frederick Moore
