OK 😊 The last time I owed one was yonks, when batteries were the norm!
Rechargeable, it's much kinder to the environment; are these still as effective and long lasting in 5 years time?
I'm sort of using mobile battery longevity rule. When I first got my OnePlus phone, a charge would last a day and half on full usage and now, I have to charge everyday.
Granted you don't use your wireless headphone continuously like your phone, so I'm probably gathering too much hay.
Not a great fan at the moment but who knows, if the sound quality improves with the advancements in technology, I may warm to it. 🙂
