My experience is similar. I recently bought a USB-C to DC jack adapter from Apple for use on my Pixel 2 phone. The sound on my SoundMagic E10 was flat and mushy. Even though the earphones are "only" rated as 46 Ohm.
KeepassX. And I'd actually rather handle password-file sharing myself as I'm not super comfortable with everyone having access to my password-file even though it's encrypted. Also the fact that my main platforms are Linux and Android removes quite a lot of options as far as password managers go.
Every so often, for instance when I am setting up my password manager on a new device I find myself reading the password from one device and typing it on the next. This would make that process much easier/saner. The password is effectively much easier to read in and type back.
