I own these and highly recommend them. Correct tip selection is a must. Wide bore tips work best in bringing out the full sound. Otherwise, with narrow bores, the sound can be overly dark. They also benefit from a day or two of burn in. Again, they can sound dark when you first get them. I run mine balanced, with a cable provided for me by the seller I got them from in China, run them out of an iBasso DX200 amp8, and an iBasso DX120. They sound great out of each. They are easily worth twice the price being offered here on Massdrop.
