Personal Note: What I have noticed is that most of these audio splitter cables seems like it was "designed" for devices that already have an independent sound control. What made me give comfort a 4 instead of a 5 is mostly because I have locked hair, and if I wear my hair back it presses against a few locks and feels like it’s digging in. I just wish it can n black. I ordered a size 2. Will update this review after about a week or so once Ive had a chance to actually test their performance. $ The only snag is the sizing: the first two pairs were fine, the next from a different supplier were much too small although I ordered the same size apparently. It is made of bamboo painted with very good paint. It even came with a free screen protector and cleaning cloth! LED indicator for charging status is extremely subtle and for a moment there I thought there is no voltage present.
