These are awesome headphones, but time for a change.
Excellent condition, full working order, recent new genuine Grado earcups.
One of the many superlative reviews - https://www.trustedreviews.com/reviews/grado-ps1000
I don't have the original box.
Over £1800 rrp.
£450 + £10 RMSD in the UK.
Might consider swaps / px for other hifi goodies.
