These Bluetooth headphones are made well and are a good quality. The sound is great, which I think is the most important thing. The music sounds clear and the bass is fairly good. I use them connected to my android phone. It was easy to pair and now connects well and stays connected.
They fold up easily and also the arms extend well to make them the correct size and they stay in place. They are comfortable in the ears and head.
The longest I've worn them between charges is 5 hours so they hold plenty of charge. They are easy to charge and it doesn't take too long.
The only negatives I have are that the volume is always on full blast when I turn them on, even if I've just had my phone at a lower volume. And the controls could be more used friendly. I basically have to touch the buttons and count down to the one I want each time as they all feel the same.
All in all I would say that this is a good value good quality headset for the money.
