Hi all,

My Sennheiser HD 450BT headphones have suddenly stopped working, and I'm hoping to get some help troubleshooting as they are only 18 months old and I don't really feel like replacing them.

I cannot get the pair to turn on. When I plug the set in to charge I get a flashing blue light usually, and on occasion I have got the solid red light you'd expect for charging. However when I unplug the pair are completely dead - no response to any buttons. I have tried hard reset, holding down all buttons for 10/20/30s and I'm getting nothing. The only response I can get is the blue flashing light when plugged in, thats the only sign of life. Any help is much appreciated! Any tips on what I can do?
