## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    A "must have" should you wish to use the headphones for longer than 8 hours at a time.
  

*by S***N on Reviewed in the United States on November 27, 2014*

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."

works fine, but not easy to remove from headset

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great battery - great to have it on hand!
  

*by J***H on Reviewed in the United States on October 28, 2012*

I bought this as a spare battery for my Sennheiser MM-550's.  It's the exact same battery that comes with them already (and apparently works in many other models of Sennheisers).  That's great not only for Sennheiser (cheaper production), but great for the customer --one battery, many models of headphones.What I like the most about this battery?  Two things:1. Long life - it lasts between 8-10 hours on average for listening to music (depending on settings, volume, etc)2. You can charge it via MicroUSB without it being inside the headphones.I usually am using my headphones and, when needed, charging the second set.  I use my 550's about 8-10 hours/day each day.That being said, one way to drain your battery much quicker is when you're using it as a headset (talking on the phone).
