Summary: really liked this unit. I was able to use the voice activated features plus non voice. I am on the go all the time and do not believe in answering the phone while driving. This helped with that and while I am working in the shop or outside with saws and such.I could hear the call ring through when I got a call. Normally I would not. voice coming in and going out was clear and non distorted. Easy to fit to your ear and comfortable.
Best on the market in this price range,excellant product!

Summary: I have several bluetooth headsets but none would work with my LG L39C Smartphone. Read reviews for M55 and it seemed to be the one to do the job. As soon as I received it, put on charger took 1 hour. This item is very good transmit and receive, loud enough clarity is real good. The greatest thing for me is the comfort if the earbud, you don't have to worry about fit, it is snug and will not come out even when skydiving!
Summary: ordered 2 of these, they are the BEST. you can tell it to answer, ignore, end call, and even read your texts to you and reply. no background noise, and you can hear great. you get a full day and a half of use on a single charge. going to buy another one to have on hand.
Decent value for the price, but for simple quiet areas.

Summary: I purchased this headset to use while working in the masonry business. It seemed that its noise canceling capabilities would be an awesome use. Little did I know what was in store. This headset has limits to its good. For pro's, its easy to set up and use. You just push certain buttons to do what you want and it responds. Its range is very good and the design looks awesome. For the con's, my ear pains something terrible after use of long periods of time (over 2 hours).
Prompt service and delivery AAAA++++++++++++++++++++++++

Summary: I bought this product so that I would be hands free while driving my car and around my house. I have the other plantronics headsets and they have just worn out over the years. Great product and long battery.
