Net on the tests are true: these headphones have an excellent price / quality, probably the best in their price range. I tried 4 times more expensive that were not his level best (but had a lot of useful connectivity accessories). the only flaw of the E10 apart from the lack of accessories warranted at this price, it is the low quality silicone tips. otherwise, after 5 minutes of listening to get used to the comfort and sound, it is a pleasure to listen to his favorite songs :-) beautiful sound definition, for more accurate descriptions g ** gle is your friend ;-)
