Review: A "must have" should you wish to use the headphones for longer than 8 hours at a time. - Great for those long 14 hour flights where all there is to do is watch one movie after another. I keep two extra batteries fully charged in the zipper pocket that came in the headphone case. That way, not only do I have enough power to fly long distances, but also to move through airports etc. One thing about changing the battery is that changing the battery can be a challenge at times. The rubberized tab which is a cover for the charging port is convenient to pull the battery out. That is, until the tab becomes pulled off after trying to change the battery this way. Otherwise, it is a definite challenge to get the dead battery out of the unit in order to push in a freshly charged battery. Given this battery is the only choice for this purpose, it is a "must have."
Review: Gerat small Power for great Bluetooth Sound Canx Headphones. - The Sennheiser Bluetooth Noise Canx Headphone battery last about a year of recharges. I purchased 2 and the cost is reasonable. They hold a 7 hr Charge at Noise Canceling and bluetooth active. Highly Recommend. Remember that when you put in a new battery if the unit does not power up it's most likely a flat battery. But new battery is a lot less costly than a new pair of Headphones. Good overall value.

### ⭐ Has died within 2 months 4 times now, buyers advised.
*by S***O on December 21, 2015*

I'd used Sennheiser for years and when I decided I wanted a bluetooth headset I went with the m500x, after about a year the headband broke and sennheiser warranty service replaced the headphones and gave me an upgraded me to m550x's. Then the issue with the battery started. After owning the m550x for about 2 months the battery died. After calling it and senneheiser's warranty people replacing it no problem it lasted again about two months. Sennheiser's rep told me they replace the battery once and only once for customers, so I decided maybe I got a lemon and bought this battery off amazon. Its the same battery that came with the m550x, same one they put it at the factory. Died in 2 weeks. Amazon RMA'd it for me no problem. As of now, 33 days after receiving the replacement pair, it has broken again. It will not charge and after experiencing this for the 4th time I know it will never live again. I'm seriously considering tossing the entire headset over these battery issues. I love my m550x's, its a great headset. This is downright infuriating after all the problems I've had this battery. Beware.
