Bluetooth headphones (Perivale UB6)

I bought it from Tescos to try it out then asked a refund which was denied as they say it's due to hygiene reasons. Anyway, it comes with its own charger but have to use your phone's plug to connect the USB end to it and the magnetic small end plug powers it. It was ok to use until the battery life only lasted 45 minutes of use from listening to song from You Tube on my phone. Not keen on the idea of an over ear device. Yours if you want it. Thanks.
