They are comfortable, the straps do not rub or chafe. The sound improves slightly with the amp - but man it?s negligible and if I didn?t have it to compare directly, I wouldn?t miss it. But so do the AirPod pros in a different way. Nice summer color My main system consists of digital preamp, power amp and a pair of ribbon panel speakers; the combined cost is almost like a small sedan. Love these Sandals-Not just forSpecial Occasions & Warm weather. 4Ghz dongle and have not tried with my tablet. A couple of things to point out. They seem to be very durable and will hopefully hold up for most of the school year. Cant wait to try it in wet weather!
