3 Flashing Red Lights & Sennheiser Support

My Momentum 4's are currently toast. The dreaded 3 red lights syndrome. Sometimes, just sometimes, I can persuade them to turn on and they seem stable enough as long as they remain active. Sufficiently stable to allow me to update to 3.84.3 the other day.

But currently I have a pair of expensive (to me at least) less than a year-old headphones that are USELESS. I plan to go away for a couple of weeks shortly and was relying on them to accompany me.

I registered the complaint with Sennheiser support several days ago and apart from being assigned a ticket have heard nothing.

What's even more annoying is that I only occasionally wear them, almost exclusively in the house, they've never been out in the damp and I have never exercised or sweated heavily whilst wearing them so it's not the usual suspect. It just happened! Probably after less than 50 hours use!

Anyone got any idea how long support take to get round to a request that is obviously pretty severe?

Not a happy bunny!
