Yanyin Canon ii iem high quality earphones

I am sadly selling these pretty iems because I also have another pair and cannot afford both.

They have very nice bass and precise details.
Very good condition, no defects in appearence or sound.

It is possible to tune the bass response through two switches.

Example review found online:

"The Yanyin Canon II completely redefined my idea of what I liked in IEMs. It provides such a rich, deep and nuanced bass while keeping a harmonious balance on the midrange and treble. Never has a set captivated me this much, and it truly is a feat considering its $379 asking price. It’s not perfect, as the treble might come across a little gritty and a lack of accessories. But all is well considering how good this thing sounds as a whole. RECOMMENDED!"
