ARETE, a hybrid IEM featuring 1DD and 4BA drivers. I've used it for about a week, but personally, I didn't feel the imaging was as good as I expected, so I've decided to sell it now that I have some free time at the end of the year. - Model Name: ARETE - Driver Configuration: 1 DD + 4 BA - Brand: ZIGGAAT - Features: Hybrid IEM Thank you for looking.
