I recently bought the Edifier W800BT bluetooth headphones which i was very happy with (especially at the price point). But the happiness was short lived as I now can a very strange error that I have not been able to fix....I have no trouble connecting the bluetooth, it connects straight away with no trouble. However, when I try to listen to anything, no sounds will play (except for system sounds for some reason) and after not hearing anything for about 15 seconds the headphones will automatically disconnect themselves and refuse to reconnect until I restart them. Can this be fixed? or is it more likely faulty hardware?
