Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.

Scenario: 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.
