I bought a refurbished version of these headphones. I recommend refurbished electronics from manufacturers or dealers who are responsible for their work. Refurbished (different and better than refurbished) saves money without sacrificing quality. I wear Bluetooth hearing aids; So, in my case, there's no need for a wireless connection (the headphones still pair easily and the sound quality is excellent). What I really wanted was noise reduction for aircraft engine noise, which makes it very difficult to hear dialogue in movies and TV shows in flight. I am very pleased with how well this headset does its job. The roar of the engines is reduced to a simple hiss that is easy to ignore. I enjoyed two movies on my last flight. The manual states that after fully charging the battery, the earbuds should provide over 20 hours (it says more, but you should have at least that much time) of listening time. This week I'll be flying small planes, which are often even louder than larger models. If I feel the experience requires changes I will edit this review.
