My Physics Prep Room opens off one of the labs - no direct access to a corridor.
For ad-free, calming music, I have a Sony CFD 5100L (CDs, Cassettes, Radio). This can be employed when no classes are expected in College.
For at-desk work, the S-DOG speakers (illustrated) plug in and come out to play. I wouldn't describe them as serious woofers).
In term time, I use small lightweight headphones to listen to training videos or e.g. The Feynman Lectures audio streams. I can easily hear someone talking to me while wearing these.
For Teams/Zoom meetings, I wear my Sennheiser headphones (new in 1990). Comfy and they don't bleed audio feedback into the mike.
