I'd love to hear if Sennheiser is planning on amping up their game when it comes to supporting longtime customers.
I purchased +400 € headphones but can't get a replacement battery. Trying to get one for my MM-550 XT for several years now. It seems impossible.
Since the "
BA 370 PX
rechargeable battery" is suitable for other Sennheiser products
_(MM 400, MM 400-X, MM 450, MM 450-X, MM 500-X, MM-550-X, PX 210 BT, PX 310 BT, PXC 310 BT, PX 360 BT, PCX 360 BT)_
I imagine I'm not alone.
Side note: the material quality on this model was sub par.
