A steal at this price. I paid $70 and feel like I got a bargain. I've had much more expensive IEMs and keep coming back to the e80. I run these via a Dragonfly Red out of my computer, and the imaging, instrument separation, top-to-bottom coherence, and musicality are all excellent. Slightly U-shaped sound with smooth mids and crips highs, and enough bass to really fill out the bottom without muddying up the sound. My current favorite IEMs, they scale really well with better sources and amps (and I'd advise using an amp with these, they are somewhat hard to drive for IEMs--the only fault they have, if you can call it a fault. I think it's an advantage since they are also well damped and don't suffer from hiss or impedance matching issues like many sensitive IEMs).
