Ok, so ill start with the most important bit, the sound:
Its breathtaking for a set of in the ear cheap headphones. Bass is great, mids are fantastic and the top end is defined and punchy as well, far better than i expected for headphones of this price range.
Now onto my negative points:
Thats the design, they are heavy, really heavy for in the ears, they use a Y shaped cable setup which again isnt great, would have been far nicer to have the short and long cable you can wrap round your neck, finally the cable is short, I have my Iphone in my denims pocket and the cable is just long enough and no more..
These could have been epic, but its the design that lets them down. Reduce the weight, long cable to wrap round your neck and a longer overall cable and they would be the best headphones ive used, thats even competing them against ones of 100 pounds.
