My single-occupant Pontoon boat, with a full-sized battery Trolling Motor and gear was too heavy for the 1. Entweder waren sie zu klein, zu eng oder verursachten bei ihm Schweißfüsse. I waited to give this review. 5 with a normal, slightly narrow foot and bought a 7. The sound is good and after learning how to use the volume control, I can easily go back and forth between music while working, to my work call and meeting applications. They?re super flattering too! I will continue to purchase TEVA! I have been looking for a charger that can be carried around the world without carrying an adapter and can be easily put in my pocket. I like the overall quality of the bars. The battery life is good enough that I haven?t listen to music long enough for the battery to have actually died.
