Absolute rubbish. They fall out of your ear unless you are perfectly still. When you walk along the clunky mic/remote bounces about making a thudding noise over your music. The remote pauses when you try to change volume and vice versa. The wire isn't tangle free at all.
A few months after buying them (and rarely using them due to their fiddliness) they broke. First the remote stopped working, and then one of the ear pieces stopped working. They're now sat in my bin. A £2 fake Sony pair I bought from a market in Vietnam was better than these!
Nice product. Came as described. It looks a little fake, but it works fine. It has the same features as the original iphone earphones (skip track, volume, mic, etc. I've been using it for a week or so, and hadn't any problems in my communication. The earbuds are a little difficult to get used to, because they go into the ear and aren't like the common ones. But, they are completely sound cancelling from outside noises. Overall, a nice product. Couldn't hurt to be a little cheaper, though.
