Ira Carmichael rated us:
: (4/5)
Product:: Sennheiser MM 450 battery (270 mAh 3.7 V, Black)
General:: I was having a hard time finding a battery for my Bluetooth Senheisser Headphones so appreciated that your company had them available.
About the product:: The product is performing as expected. I am hoping that this product has a better lifespan than the original and other replacements that I have found online. Time will tell. I use this headset on a daily basis and was getting 3 months out of batteries before they stopped charging.
