Don't get me wrong, the sound quality of these earphones are amazing. You certainly get what you pay for, if not more in regards to the quality of sound.
A couple issues I have with these earphones is that the remote on the earphones lets you control whether to fast forward, playback tracks and pause for my iphone, which is great. But the one thing it doesn't do is control the volume. This means I have to carry the phone in my hand and change volume from my iphone, rather than tucking the iphone away in my pocket.
The other issue may just be me as I have very small ear holes, but the earpieces supplied with the unit don't fit in my earholes. The only ones that fit are the foam ones.
All in all, if it wasn't for the 2 issue I mentioned earlier this would be a fantastic buy, as I doubt you could find such good sound quality elsewhere for this price, but I could only give this item 3 stars because of the other personal issues I had.
