Comode. Cons: Im giving this 4 stars because first impressions were just ok. 5 -7 Wide in a walking shoe and ordered the slippers in a size 7. Doctor said it was irritated looked fine. The original ones did last a full year, so we will see how long these last. Very sturdy, I have had it on for 1 month so far, has not been a problem for me in terms of falling off or becoming loose while driving etc. Or take off and have to keep looking for them. In order to ensure that it didnt blow off I used a couple of bungee cords: One wrapped through the eyelets that are on the front (meant so you can lock it) attaching it to the back of the frame on one of the bikes and then wrapped the other over the top around the back of the bikes. It has a good build quality and seems like it will survive some travel, the arm is also metal and feels pretty sturdy. They are the first completely wireless earbuds Ive had that dont hurt my ears and dont fall out, and on top of that have a great sound.
