If all goes well I will probably buy again . Sound is clean and clear. Im not sure if these are too long for my ears or what, Im having a hard time wearing them securely while blocking out sound - tho I did take a tip from another reviewer and opened my jaw while inserting the ear plugs and that does seem to help. We had bought a Bluetooth transmitter that was also not compatible with the headphones. I was getting a bit fed up with the problems I had been having with their products, previously I had been using their G1 / G3 Mice which lasted nearly 3 - 4 years without problem, and usually failed due to damage to the optical lenses, or just some kind of connection error. I generally love their flip/flops, these just have an off cut? The length was fine, the toe, front-ball area is awkwardly fitting. They fit great, are durable, and as far as I can tell, theyre actual Crocs. The fit and finish is great and they are surprisingly attractive in person. I get a fairly consistent 8+ hours of play time out of them. It arrived very well packaged.
