Title says it all. Hifiman's NEVER go on sale. Go to Razor Dog Audio and grab one today. Hifiman HE-400 for $299 with FS.
They also have coupons, but they don't work on Hifimans. Then I got an email saying that I could take off $50 to get a new HE500 for just $549 (MSRP $699, Sale $599)
Didn't take the deal, but this is just for anyone interested in trying out planar dynamics
