I bought off their original owners, in original cases, a Hifiman HE-500 and an Ultrasone Signature Studio.

For the grand total of (Australian) $400 for both.

Had I bought the Ultrasones just 2 yrs ago when you could still buy them new here they were over $1400 by themselves. Still have to email them to see how much warranty is left.

If you can find a pair, OG HE-500. I love mine so much they retired my HE-5XX’s.
