A buddy of mine helped me fix the charging port on the headset which had broken off after the years of use and replace the battery. She is 55" and 126lbs and it fits perfectly. I have used these not only for music but also for noisy campgrounds and slept blissfully unaware of nearby parties. If he really needed them I could cut some button symbols from permanent vinyl for an easy fix. If you need to adhere rubber, plastic, canvas, leather, fabric, or other shoe-type materials, this stuff does the trick and it really sticks. I really wanted to like this headset, but Im so disappointed in it. It?s going to be a matter of time before these Bowers grab the attention of established online reviewers. Arrived with 7 of the 16 glass jars broken into tiny and dangerous shards and slivers, and the spices themselves loose in the cardboard packaging. I tried them on when I got them and walked maybe a hundred feet if that much. I have to say I have no idea what they were listening to, I wouldnt say they awful, just a standard pair £30 headphones.
