Finding a Bluetooth headset that fits snugly in the ear and feels comfortable to wear can be tricky. Fortunately, the Plantronics M100 satisfies on both counts.
The Plantronics M100 has other strengths, too; but a few weaknesses leave it in the middle of the pack.
Available with five different colour accents, the Plantronics M100 distinguishes itself with a lightweight, svelte design. It weighs 9 grams, and comes with three different-size ear gels and an over-the-ear loop that feels comfortable and easy to place, despite being fairly rigid. The device is notably less obtrusive than some of Plantronics's previous offerings.
One point that impressed us: Upon sliding the power switch, the headset reports the number of hours of talk time left, and it appears to do so accurately. Plantronics rates the Plantronics M100 at up to 6 hours of talk time and up to 10 days of standby time; plus, as the specs promise, we found it charged efficiently, requiring just 1.5 hours to achieve a full charge.
Plantronics positions, and prices, the headset in the middle of its lineup. As such, we weren't surprised to find the audio quality good, but not knock–our–socks–off great. The headset has dual microphones and DSP (digital signal processor) noise cancellation. While callees were generally satisfied by the headset's clear audio, occasionally even the built-in wind-noise reduction and echo cancellation couldn't squash the background noise in places like a crowded restaurant.
Moreover, while we were largely satisfied with the audio, we could sometimes perceive a hissing noise during calls.
The Plantronics M100 headset charges via a micro-USB port, and has volume and disengage buttons in addition to the power switch.
We liked how the Plantronics M100 headset paired quickly with Bluetooth–enabled phones, and particularly loved the iPhone battery gauge that popped up on-screen while the headset was paired with the phone.
The various voice prompts were convenient, and the buttons were easy to feel by touch. We did find that to hang up a call, the headset pressed into our ear a bit more than we liked, but that's a minor gripe - especially considering that the headset felt comfortable in-ear for extended periods of time.
