    Was not happy with the product. I guess I bought it for the name. It didn't seem to stay around my neck properly and I didn't really care for the earbuds. All in all it was OK but not what I was looking for.

    Picks up lots of noises like the brushing of the piece against the collar and such. Not something I would purchase again.

    I have owned two pairs of these in the past. First pair was great. Lasted a very long time and I loved them. Then the ear piece broke. I ordered another pair on amazon. Worked for 1 week then just died. Wouldn’t turn on or charge or anything. I thought Mayne they were a knockoff. And this time ordered from bestbuy. Lasted 3 weeks then died. Same thing just stopped working. Won’t turn on our charge or anything. They are too expensive to be made this poorly. Horribly disappointed

    The buttons are not easy to use to turn on. I try to change the song on my phone from the headset but it does not allow me to. I had a LG that went bad and it was way better than this one.

    Not the best at using during driving. Mic is not the best unless its perfectly quiet. I think sony could have done a heck of a lot better

    Static and you can hear every move you make through headset and it is highly annoying. For the price and being Sony, i am highly disappointed
