Pros: This Bluetooth gets good reception and those being called have no complaints about the sound quality but this unit has one major problem.
Cons: Unlike the M155 that had a recessed answer button that made it very difficult to accidentally activate, the M55 has a button integrated into the top half of the outer wall that makes it extremely easy to push in, causing accidental dials and accidentally hanging up on calls. Do not get this unit ...
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.
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: Today I bought these headphones and I was disappointed. Weak signal between them and the phone so that the connection is often interrupted. Tomorrow brings them back in shop and I will never buy anything from Plantronics Company
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.
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.
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.
Summary: Skräp! Räckvidd varierar från några decimeter till några meter. Det går t.ex. inte att ha telefonen i en ficka längre bort än bröstfickan på samma sida. Och man kan inte gå runt i samma rum, om den ligger på ett bord.
