FAQ about our Sennheiser MM 450-X Wireless Headset battery and charger:
Compatible replacement battery vs. OEM originals:
Our Wireless Headsets batteries are always lower in price and will meet or exceed the
performance of the original Sennheiser MM 450-X Wireless Headset battery. Batteries can sometimes
even contain identical battery cells
as the OEM original did, but lacking the brand name, can be offered at a discount prices.
Our MM 450-X battery is covered by a 3 year limited warranty, far longer than the
warranty on your original Sennheiser MM 450-X Wireless Headset battery.
