I've bought this headset about 6 month ago. Everything is perfect except... After the most recent (or previous one) firmware I've started to facing a problems with the battery. I mostly listening a music from an old iPod Nano or watching a movies from a laptop at ~ 40-60% volume. I've noticed that the headphones are draining their battery after ~2.5 hours, then the girl inside of the headphones telling me a couple of times about weak battery level and subsequently turns them off. Earlier, the headphones are kept good, 5-6 hours with active noise cancellation. Please help.
