I have been using these Noise Shots-X5 wireless headphones for over a month and my review is as follows: 1. I have been listening to songs / watching movies for over 3 hours (have not tried any more). The power bank has an additional battery, hence I have never run of power. 2. It can connect to two mobile devices at the same time. I am using two Iphones and the it works like charm. 3. I have connected these with Amazon Firestick and watching videos/movies without any hassles. However, my firestick remote doesn't have the volume button, hence cannot control the volume on the headsets!! 4. Have not tried it in rain, hence cannot comment on its waterproof properties. 5. I have also used it in single pairing mode, so either of the Left or Right device can simultaneously connect to two mobile devices at the same time. 6. These are very comfortable if you choose the right ear extensions. They do not fall of easily while walking/running. 7. Outside noise reduction is good.
Overall a decent product at this price range. Highly recommended.
