I've been using these (mini, USB-C) for a few months now and it is exactly what I was looking for. Great for long runs, easy to adjust volume to match surroundings, and no issues in the rain. Because they are open-ear it can be hard to hear when next to heavy traffic, but that is to be expected.
For the same price there are better options in the market in terms of audio quality. Poor sound, especially with the bass. This model isn't even supported by the app. The only advantage: It allows you to stay aware of your surroundings, which is useful on the street and at work, and has adequate sound quality for phone calls, but is otherwise nothing special.
Great feel and functionality, but needing a propriety charging cable is a HUGE problem. I get that it probably helps with the water and sweat resistance, but I would much rather risk some damage than have to carry around my ONE charger wherever I go.
Glad I found these! So much better to be able to hear your surroundings and people approaching from behind while listening to music. I think I have a normal Woman's sized head and the minis fit perfect.
