Jazz is sounding especially good on the Grados.
I just got a pair of Grado 325’s Steve. Surprisingly good. Nothing close to speakers, but better than the Sennheiser they replaced.
I’m just not a headphone guy, but, thinking way ahead when I could be forced out of my home for potential health reasons (yes, I’m seeing it in my 87 yo mother as you are). So, checking out whether the Grado sound may be acceptable for that use in an apartment, should it ever come to that. Purchased an inexpensive tube Bellari headphone amp, which is pretty good for the cost. Replaced the crappy stock tube with an EI Smooth plate 12AX7 tube, manufactured with Telefunken machinery. A nice tube actually compared to other I have, including my old Tele smooth plates.
