I refurbished a pair of old Sennheiser HD-25s I’ve had since 1998ish recently.

They work just like new and there is something really satisfying about bringing old tech back to a useful life.

I’m using them for monitoring things that don’t have Bluetooth.

I still use AirPods day to day though because it’s so useful to always have something in your pocket that can block unpleasant noise. Bluetooth works fine for me.
