I think you overestimate how quickly the battery will deteriorate. I have a pair of bluetooth headphones with a rechargable battery that have been working perfect for 4 years now.

Yep. I've a pair of Somy XM3 headphones that were bought on launch (Jan last year). I'm still getting 25+ hours of battery life out of them (charging them every 3 days, with 8-9 hours of use most days).
