Excerpt: I just received my new headset today and began testing it out- I was getting garble sounds and distortion on both ends when I was only about 15ft away from the phone (if that)- this is absolutely unacceptable. My second issue is the one that was mentioned by other reviewers: the button that you are supposed to tap to answer/end/redial calls is more than a little touchy - if you barely bump it, it depresses..
Excerpt: Really bad product, I have the same problem of putting my phone in my pants packet and the music cuts off. And there is no way to update the software of the head set. If I put the cell on my desk and next to me the audio will still cut off awaful product, I do not recommend it.
Excerpt: I bought this headset 4 days ago and it's very very bad its installed on Galaxy Note 2. This is my 4th plantronics after(M25, M50, M100) i bought it from amazon without even thinking twice. My last headset was M50 and it was perfect i loved it very much but i lost it. So i thought M55 will be better by any mean.
1- I received it in a poor ordinary brown box not the original box.
Summary: The product was sold as new but came in a scotch taped plastic bag and rubber band The unit never worked even after charging for 24 hours. This is the second unit that I have bought that did not work.
Excerpt: The setup of this device was extremely easy. Unfortunately, I couldn't hear the other party despite them being able to hear me. Set up the headset with two different cellphones with the same result. Have contacted Plantronics and requested a replacement. Hopefully that one will work. I can already tell that the buttons are such that many unintended functions are initiated just by touching the headset to adjust it. Wouldn't order this same model again.
Excerpt: About 80% of everything you do with this ear-piece will be unintentional! You will accidentally cut people off in the middle of a call when you slightly adjust the earpiece. You will accidentally dial the last number by accidentally tapping the dial button twice. The bluetooth range is nowhere near the 10 meters as stated. Simply the worst ear-piece I've ever purchased! Does anyone actually test them???
