Open-box Hifiman HE-400 for $260

If you are comfortable with open-box headphones, the HifiMan HE-400 planar-magnetic over-ears are offered for $260 with free shipping in open-box condition (instead of their new condition price of $300) by Razor Dog Audio eBay store. The description there says “store demo, less than 2 hours, 100% perfect”. The eBay’s quasi-haggling “Best Offer’ is not enable for this listing.
