The finish is excellent, autonomy as well (full day with transportation dej + Pause)
The application works very well (one can keep his youtubes clips on his phone, it's great)
I use it at the gym, and I have never met a particular problem, it holds well and is very comfortable.
In sound, this is very good, one can listen to everything, it remains still well balanced.
To summarize, it is a very good product, versatile and well thought out.
Thank you Amazon, price and delivery always on top ;-)
