In a very short time it makes ears ache, that is why it is very uncomfortable. And also not suitable for use with laptop via bluetooth. Because it is not well responsive .. you can't listen to a song without stopping a few times. (Dont even think watching a film, you cant bc not synchronized with video) And also it really does not make sense to use a headset which gives light constantly. With cell phone use again it stops responding sometimes although not as frequent as with laptop, which again does not make any sense to buy it. And it is too sensitive; stopping (whyever it stops!) goes to another song while the one is not finished yet. So, totally disappointment. Never ever think of buying it.
