Nah, those are fine off of regular power. The 80 ohm need a dedicated amp, but the 32s are fine in anything I ever tried them in.
Edit: with the 80s, the amp can be part of a player or whatever, but it’ll need to be strong enough, and your average phone or sound card on a pc isn’t. My lg g7 can handle the 80 ohm fine, but my oneplus can’t, as an example. The oneplus has to be cranked fully to be reasonably audible.
