Son muy grandes y se salen a veces muy facil I regret having to return them. I bought my regular size and it works for me . Its been working fine, until recently, 2 months out of my warranty, the left ear cup completely went silent. They are super cute and practical. I have always used a bladder for hydration before but these bottles are great. The box was very damaged I am surprised that the item wasn’t damaged I have to disconnect the BT, then wait for the speaker to reset itself. The quality of the sandal is alright. I bought my first pair several years ago, before they shipped with the Comply Foam ear tips.
