I’m fed up

I’ve been trying to get the firmware to update with the Momentum TW4s for hours now with it always crashing at exactly 24%. There were a few times it went up to 100% but still would say “something went wrong”.

I’ve been a sennheiser fan for at least a decade now and this is the first time I’ve been disappointed.

If anyone can tell me what the secret is to actually upgrading this firmware so I don’t hear this ringing bs from the ANC, I would really appreciate it. Otherwise, back to Best Buy they go.
