For me, it’s an electric toothbrush. It doesn’t matter if you go with Sonicare or Oral-B, once you start using an electric toothbrush, regular toothbrushes don’t ever feel like they clean your teeth properly. The smooth plaque-free top layer of your teeth that you can feel after using an electric toothbrush can’t be replicated with a regular toothbrush.
Any recs?
I’ve bought a Hiby R3 Pro II a while back and it’s amazing. The build quality is top notch, the battery lasts for 20+ hours and it has basically everything one could need; USB-C, Bluetooth with Apt-X and LDAC, a good screen and a balanced output with plenty of power.
Even rudimentary support for Tidal and Qobuz. The only downside is that there’s no storage built-in, but you can use microSD cards up to 2TB.
Mechen! Love it plus it’s pretty
You probably want to pick something supported by the Rockbox firmware, in case the native firmware is so-so.
