Plantronics M3500

Quick Take: Although light and compact, the Plantronics M3500 Bluetooth headset is made of firm, unyielding plastic, resulting in an uncomfortable fit. The inflexible ear hook doesn't help things either, and the tiny buttons are difficult to manipulate.

What the headset lacks in comfort, however, it makes up in sound quality. We tested the headset on the Nokia 6820, the Motorola V600, and the Sony Ericsson T616. The overall performance was generally good, with first-rate volume control and solid sound clarity. Yet we sometimes found the headset picking up too much wind noise. Plantronics promises 3.4 hours of talk time and 3.2 days of standby time. In our tests, we found that the standby time is closer to 3 days.
