Summary: I normally don't write reviews, but I was very frustrated with this product. I recived a product that was obviously refurbished (it appeared to have make-up in the microphone holes) I wasn't even going to send it back...I figured I'd disinfect it with a clorox wipe and it would be ok, but when I charged it overnight....it only held a charge for 20 minutes. My wife has this same model bluetooth and her's works flawlessly.
Summary: I was expecting at other gel earbubs, when i'm driving in my car with my window down i can't hear and the person on the other end and they can't hear me either, i feel that i got a use product. It also does not connect when i say answer or ignore. the sound is clear as long as there's no back ground noise. VERY DISAPPOINTED!!
Summary: Ive never had luck with any bluetooth headset - even higher end ones. Either hardware failures or never fit well or no one could understand me when I would talk thru it. I quit buying them. After a few years I figured the tech got better on them. I saw it on sale and read the reviews. High percentage of great reviews. I got it. Initially it worked great. Fit well. People could understand me. I thought this was the one for me. Within 2 weeks it dies out of nowhere.
Pros: Shipping was EXTREMELY fast for eggsaver (free shipping). Was on sale.
Cons: Just like any other BT earpiece out there. Died within 2 weeks. Warranty expired only 2 weeks after owning it.
Summary: My friend and I each purchased the M155 and we have not found it to be satisfactory, despite the good to great ratings others have given it. The problem with maintaining a connection to the phone seems to be getting worse. It used to announce right away that your were disconnected - that at least was polite.
Pros: Affordable; Good sound quality for music; decent voice quality; nice size and style
Cons: This bluetooth will loose its connection with the phone if you leave the room, turn your head or stick your phone in your back pocket or handbag.
Summary: the pluses it is cool looking goes great with iPhone the negatives if something gets in-between it and the phone, say like, your Head, (example its in left ear and phone in right pocket) you will lose connection.. also one downside of its cool lookingness and its size is that its very easy to lose.
Summary: Good looking. but feature and functionality wise, I can't hear who I am talking to when I'm outside. Will give this to a friend instead and bought the headsets with noise cancellation features.
