We had no issues in this regard because I covered the clips on all of the straps the fingertips of a rubber glove and secured them with rubber bands. Just had to look at the box to make sure i did everything right. but my heel and ankle run in a straight line so the were alas too big. Well made bc I popped some off trying to squeeze in and it still looks good. ) They arent complicated to charge or pair and are good for both men and women. To me, the difference was not noticeable in most environments, but quite apparent when listening to white noise (more midrange frequencies in Low than in High mode) and also Low works best for windy environments where High mode creates weird audio artifacts. I am a 7-1/2 and ordered the 8. 6 months okay, 3 months not worth the money. 5 but it came in a 49cm which is a little big As you can see, the design is unique and eye catching.
