I?ve hiked in them already and they?re super comfy and supportive and they look great! Clamps are a little difficult to tighten and sometimes the mike slips. Amazing quality - so comfortable and cosy, but they need to be to justify the enormous cost! A-players like to work together, not tolerate B-players. I hope this help My daughter is 8, and loves to listen to audio books. If anything I felt that the headphones could have been a bit louder ? they seem to need more driving than previous versions so I guess the impedance has been tweaked to accommodate the ANC?All in all, these are beautifully constructed, beautifully sounding headphones with excellent ANC (though not up to the level of Sony or Bose) which will delight fans of good quality audio ? but a few of the luxury touches have gone AWOL with the introduction of the high tech ANC and that?s a bit of a shame ? I dropped the Allen wrench 30xs but i did it! Super bummed that these started to fail only after less than 2 months. Every caller has even said they could not tell I was driving and airport background noise is significantly reduced.
