Classic AKG 501 headphones -- original, extra clean and perform perfectly! I purchased from the original owner who used them very little and kept them in great shape as you can see. Rated an 8 for age and the missing brand plate on the left ear cup.

These need a good headphone amp to drive them properly, unfortunately my DAC isn't a great match. Wonderful, open sounding and very comfortable:

○ Type : Over-ear / Open-back
○ Measured weight : 260g
○ Impedance : 120 Ohms
○ Sensitivity : ~89dB/mW (some specs show 94dB)

Thanks for your interest!
