Wouldn?t recommend for travel however this is more of a at home stay in one place charger. They fit over the ear not in it and I could close the boom and put it in my pocket for when I needed it. It seems to be very sensitive and tries too hard to control extraneous noises. If you were just using it while sitting or under your desk you would probably be fine but not a good piece of equipment if you want to get a good cardio in with some speed. Not a happy customer. this was always a problem with the popsocket. Today the weather was nice so I wore them to putt putt. The company seems responsible as well, highly recommend any of the leather strap flip flops. A little over priced for flip flops, but I have a narrow foot and they fit well. For everyone else you can adjust the tightness on the side by pushing the gold part up towards your ankles.
