Excerpt: I found this M55 at the Mall Parking lot. I took it home Disinfected the unit and enjoyed about 8 months of usage. It has recently begun to loose connection with my IPhone. Over all I'm very pleased with the device considering I don't know the age. I have since purchased 2 as gifts.

Summary: I have only had this headset a couple weeks, used a couple of times but it works well. Suited for my purpose. I like the little extras it has as well. Good headset for the cost.

Summary: This is my first Plantronics headset & ive got to say it is a great bit of kit. It's lightweight & compact but has quite a tough feel to it. I've given up on my last headset. The battery life was getting ridiculous. Never have i needed to charge a headset up every day. So decided to try the M55.
Pros: battery life, clarity, streaming, comfort, the deep sleep mode, the android apps, the voice activcation
Cons: the gel ear tip initially. but im used to it now.
