I picked up one of the four used units I saw available directly on HiFiMAN’s website recently, for the ridiculously low price of $119, and at this price, I’m not complaining! Definitely a little cosmetic damage but everything looks relatively good to me and they sound pretty great for $119.
I definitely noticed they roll off earlier in the sub bass region than my Audeze EL-8 open and my Focal Elegia. They are surprisingly driven decently off of the headphone out of a 2016 iPhone SE, particularly on Apple Music, where they are really loud one click below max volume, louder than Spotify on same track on the same phone at max volume.
I’m pleased for the price!
