I like these new earphone / microphone to talk easily. The sound quality is unprecedented, very high. The thread is long, it is also good but at times I find it too long. I am obliged to attached part, otherwise it delays me when it gets tangled, and this is very annoying, especially before going to an appointment or when I'm in a hurry. Another defect not insignificant for my taste: the tips of the headphones, go where the sound, its very uncomfortable to the ear. Indeed, beyond a piece for "the making" ear via an adaptation to the shape of the ear, it sounds to explore. And therefore only this said, when marked, it marks: it hurts. I feel the "adjuster", which exceeds the small end and brand my skin, that create pressure on and Ducout unfortunately that create redness where it is irritated, giving an impression of burning.
