Q: That 300 ohm impedence frightens me. i have ak sr25 mk2 music player i assume ok but i want to listen to movies from hifi amplifier, are both ok?

I’m not sure ….. I listen through a modestly-priced iFi dac & headphone amp and they don’t struggle at all for power 👍🙂

Q: Fast charging ? As per spec.

These headphones don't have batteries, so there's no fast charging (or any other kind of charging).
