Plantronics M100 Review
The Plantronics M100 is lightweight, at 8 grams, and only a quarter-of-an-inch thick, so it's as discreet a cheap headset as you're likely to find. It comes with several pairs of earbud covers and an ear loop. In Plantronics M100 reviews, consumers and an expert at PCMag say it's quite comfortable and stays in place securely. One consumer who posted a Plantronics M100 review at Amazon finds that you don't even have to use the hook.
The Plantronics M100 does not have the company's ace noise reduction system, but for the most part, both experts and consumers report that background noise stays fairly well contained. The headset boasts automatic volume adjustment that ups the sound of your voice when you're in a noisy environment. According to a Plantronics M100 review by an expert at Slashgear, the dual mikes effectively block noise like wind so the person on the other end of the line can't hear it. The PCMag reviewer could hear a high-speed fan, but it wasn't loud enough to disrupt a call. A user who posted a Plantronics M100 review at CNET says that while people on the other end can hear clearly, at times background noise can drown them out. One grip from an expert at CNET: To change the volume, you sometimes have to cycle through all five levels, which is a bit of a pain.
A user who posted a Plantronics M100 review at Best Buy puts the battery life at six hours of talk time, which is exactly what Plantronics claims. The battery charges fully in 90 minutes, according to the company, and half an hour of charging yields a two-hour lifespan. The battery level can be displayed on an iPhone, and there are voice alerts for battery life and connection status. The M100 also features last-number redial and voice dialing. While the headset does have multipoint technology, so you can connect to more than one phone, it is not enabled with A2DP (advanced audio distribution profile), so users can't listen to streaming music.
