a bit on the snug side to begin with but I imagine that is because leather and the ankle fabric will stretch a bit with wear. The battery drained too quick right out of the box. Feast shipping! I purchased them in the store but unfortunately the dog chewed one. 5? tall and 4. For Advanced Users: I also tried to edit the bands in developer mode, changing to LTE only and many others, I edited the APNs, I reset all configurations many times. My old pair would break up every time I leave the room for refills. Whatever size you normally wear, go one whole size up when you order these! As for battery life, I use headphone through the day for 12+ hours, you would probably need to charge everyday. Each ear worked independently.
