HD650 was modded by @purr1n around 2015-2016. Quarter mod, rear damping and foam discs removed. I think it was called the Tri-Mod. I bought this from @foo_me for $255 shipped and they've served me well. Thanks to @tommytakis I have a JAR650 on the way so it's time to pass these along. Headphones and cable, no retail box. Asking $170 shipped CONUS to friends and contributors, $200 to randos. Hifiman HE-560 was me trying this headphone out once again (now that I've heard more headphones) and finding I still don't like it. Unmodded except for a Sundara headband/chassis. Asking $170 shipped CONUS to friends and contributors, $200 to randos.
