Summary: These headphones sound great but I will have to take them back tomorrow because they will not work without battery power. For the price you pay they should be bluetooth and/or able to work without battery power.
Summary: Good replacement, bad product. These tend to break at the end of the stress reliever on the device side jack. Unfortunately these are Bose proprietary cables and when I got this no compelling alternatives existed.
Summary: I give this only 3 stars, because I have to depend on keep putting in the AAA battery. The noise cancellation does reduce the ambient noise. But is it worth the dependency on having to keep using the AAA battery?
Pros: beautiful sound!
Cons: battery dependency. can't use the headphone with noise off
Summary: I bought this product for my Bose AE2w bluetooth headphones, as they only came with a cloth bag. The headphoes don't quite fit in the case perfectly, but it gives better protection when travelling than the cloth bag supplied would. I also think the case could be a little cheaper.
