honest performance for this small price

I bought these headphones for my daughter, at the same time I wanted to see and compare the evolution compared to my Klipsch Image S4 purchased in May 2012, after a test seen on digital ... Well I am, still a little disappointed, because for almost the same price range (before the promo) no photo, these are sony withdrawals. Less sensitive, they are however specific about acute and medium but lack bass and distorted worse when they are too deep. His headphones are still much better than the majority of supplied headphones with mp3. With coupon for 20, it becomes attractive, we must recognize it.
The package comes with 3 pairs of tips 1S, 1M, 1L mounted a pair L; accessory clip and manual reel, and multi-language instructions.
