These headphones are great value and good quality. After receiving them the next day I didn't expect them to be brilliant, but they are! I ordered them because I needed a pair of head phones to plug into my piano, and this had a suitable adapter to do the job. After plugging them in i was amazed at the quality of the bass, it was powerful and clear, but it was not so much that it overpowered all the other notes. The quality of the treble is fairly reasonable, but it would've been nice for the notes to be more crisp. After that I plugged the headphones into my iPhone, I was not hugely amazed as I have a separate pair for them but these are only £5. They do feel quite comfortable to wear, especially with the padding on the earpiece (although the leather on the over the head part has quite a cheapy polyester kind of plastic, but luckily the ear-part is made of good quality imitation leather) and they do get quite hot after a while, but that happens with most headphones. I really do imagine them lasting and would definitely recommend! Me Gusta Mucho!
