For sale is a set of Sennheiser HD 497 purchased in...2000? or thereabouts.
Sound was great for the price then, is killer for the price now. Very infrequent use, near-new condition even after all this time.
Driven excellently from your iWhatsit or pretty much anything with a headphone jack. Fit is the biggest drawback, medium to smallish ears recommended. Pad adjustment is also a little finicky.
Fun, and practically free. Shipping included in sale price.
