Hey guys! Instead of waiting for Drop to get me a HD6xx in MARCH, I'd rather have a chance of listening to one of these headphones again before the world ends from COVID. Anyway, I've heard about all the HD6x0 variants. HD580, HD650, HD650 KISS, HD660s, HD58x, ect. So if you got one you want to sell, I'd love to purchase it. Unless it's a HD58x. You can keep that one. I'd be very interested to hear a HD650 JAR if anyone has one.
