I have used it for a week. The tone was even for this price range, only mediocre: Very good bass, treble poor, for the poor quality too strong volume loss (resistance), which is probably located on the connector.
After an ear and another day later the second ear was broken.
Because the stupid traders naturally did not want to pay the shipping and me especially not even able to say, if I ever get my money back, because he sent the only to manufacturers, they came into the garbage. I did not feel like such a back and forth and constant email scribblings, then at some point the 10 to get back, because the dealer is also not recommended.
Recommended in any case!
Basically, you should already rather spend 10-14 more, but you get the already really good in-ear headphones, otherwise you get this quality even for 4-5 (I paid when buying yet 10,50).
