The charger for watch is great. Upon turning it on, the speaker is making a slight static sound and has not stopped. My single-occupant Pontoon boat, with a full-sized battery Trolling Motor and gear was too heavy for the 1. I like the lock feature and hope the lever holds up after hard use, it requires a bit of force to lock/unlock. 5, these shoes are more than an inch shorter. I then found a quiet room an did the ear tests. They provide good sound, are comfortable and durable. So if you want the opinion of a fussy headphone / earphone / hifi guy - stop looking around at others and get a pair of these. Button placement - Weirdly placed buttons but I can adapt to the button positions. Looking forward to them.
