Installation was painless and these protect the delicate mesh fabric thats part of the headphone band. During periods of heavy rain all four of the clips caused leaking water to get into the car and onto us. Works like a charm and the bike doesnt swivel on the rack. Ive only used it on 2 short trips so far but can say: Sound quality is very good. Do not know how they’ll hold up because I only wore them for a couple of hours and decided to get tar and feathered is not my preference! I get closer to the 6 or 7-hour mark than 8 hours before (Usually the right earpiece) starts the annoying "BATTERY LOW" drone, which repeats 5 or so times over the course of a few minutes, then BOTH earpieces shut off. I got the leopard print, too! I will have them sewn back up but will never buy anything from the company who sells them. Even though they have been kept in their protective carrying case every single moment they were not in my ears, they fell apart like a pair of cheaply made $5 buds you can buy at the local drug store. La talla pedida no tiene que ver nada con la talla recibida.
