1. I have also an annoying noise in the headphones. especially for audiobooks or ballads annoying the powerful, otherwise it will be mostly about echoes through the music.
2. By design, these have no rubber essays as in conventional in-ears and therefore be outside noise not good enough shielded.
3. I can now say that the headphones are actually uncomfortable and pain after prolonged listening! Funnily enough, doing only my left ear hurt correctly. seems as if my left ear close ... apart from that I take off even after the handset pain in the ear and get away with it definitely!
Conclusion: if the shape fits you and you're lucky and your songs, the noise is masked, you do not much wrong. but for me definitely a bad buy, although the sound itself is for the price very good. a pity!
Amazon, of course, top again!
