This headset wears for hours without nerves due to excessive weight or excessive pressure. Outdoor (In-ear earphones keep with me not), this headset very suitable, because you still will notice traffic noise. Closed listeners are downright dangerous! In addition, the handset carries on so little that you can wear it well under a cap, in which case it naturally keeps adamant. The sound is amazing basshaltig for a small, open headphones and has a round, well-balanced overall sound. On my smartphone (Samsung S2) it is also loud enough, which is not self-evident. For very loud traffic noise but an end is reached it would still louder it would probably damage your hearing. So overall a good, comfortable to wear headphones if you want to have a low weight and a long wearing period. My Recommendation!
