there is NOTHING still in terms of detailed troubleshooting, I have no idea. De ser necesario las puedes usar todo en día sin que te molesten So Ive got the hassle of having to return them, or finding a smaller footed person to gift them to. First, the good: These headphones have a really good, fairly neutral listening profile. Now for all my big breasted females like myself. Oh - and they include 2 extra rubber rubber mounting "nets" for when the primary one experiences natural wear and tear, or if you happen to break one or two along the way. Two things that I don?t really care about, but is worth mentioning, are 1) it has no pressure sensitivity and, 2) it is not able to activate the switcher bar or bring up the app dock. I squeezed it out one time! I will surly buy for family and friends and test out many others. Definitely would purchase.
