The battery life is also very impressive with these headphones. I like the case and it?s easy to but on my key chain, but the top kept falling off and I officially can not find it. One was not worth anything, the other was difficult to use. My friends all said that I sounded super clear. I?ve wasted a lot of time on something that should take 2 minutes. They may very well last as long as real Birks. If you want shapewear this isn?t for you. Love that its easy to see/read. consigliata. I loved how it stands compact on the corner of our tiny walkway yet contains all of our shoes.
