Sennheiser HD 650 for $300

The new condition open-back over-ear Sennheiser HD650 is now down to $300 with free shipping at Amazon by Amazon actual. This looks like it could be a computer-generated price-match of a marketplace seller (but I’m only guessing at this).

Note also that there is a newer model the HD6XX that was offered a couple of times at Massdrop for $200 but sold-out within nanoseconds.
