Last night my speakers worked perfectly. This evening on trying to turn them on they do not turn on at all unfortunately. I followed advice around power cycling, unplugging for 3-4 minutes and also trying different USB ports / power sockets.
The confusing and hopefully good thing is if I put on my head phones while holding the power button on the right speaker, I can briefly hear windows register that a new device has been connected at the same time the speakers light up (after holding the power button for a while) but then they disconnect instantly and on letting the power button go the blue light above the volume button flashes for a while, the speakers cycle lights for a while, then they just turn off.
Any ideas? The speakers are only 15 months old and have not been heavily used.
