I removed one star because she has a little autonomy, at least for the intensive use that I made, it takes less time than her friends. I served often and long, and I have to charge it every other day and sometimes every day. In terms of listening, it is rather good, it can be mounted directly on the headset. We can also answer and end calls without using the phone.
For storage, the box provided, do good to me, I would have to remove the earloop every time, and I know from experience (another) it does not help. So when I serves me, I put it near the phone.
Bluetooth tends to sometimes connect and then disconnect all alone, but it is possible that it comes from my phone. Anyway, I do not regret my purchase.
