The area where the straps are sewn to the plastic should be reinforced better to prevent separation. My product didnt work correctly. Was turned on to this release by Oluvs early review. ???? I know its silly to be so excited about house sandals but I will absolutely be buying these til the day I die lol. I havent tested out the battery life yet, but I am enjoying this purchase so far. This is a great value for the money and definitely fit as described. Great value for the price. I applied the light on a 90F day and the side in the sun had the adhesive melt away from the metal while the shade side stuck fine. Bose isnt the only quality headphone manufacturer out there.
