This is I think the first headset that I have disposed of functioning. The exotic form of ear plugs at first sight suggests that the developers have done a great deal of thought. The result is sobering at least for me. The plugs sit painfully in the ears and fall out already, if you still did not move. In addition, do not touch the cable carries extremely in the ears. Not even for the low price I would recommend this product. I bought more back Sennheiser for a few euros and am as usual happy with it. My tip: Even if so small headphones not have eternal life, prefer to invest a few euros more.
