These are hands down one of the best IEM I have heard to date. Perfect balance between fun and analytical. I briefly listened to Aroma Jewel and these stand tow to toe with them in my listening section. The Ace unfortunately went under the radar once Aroma audio became popular and the release of Jewel.

Reason for selling: my left ear is smaller than my right so they start getting uncomfortable after 2 hours.

Included: 3 cables (3.5mm, 4.4mm & 2.5mm). 2 ear tips and the ones I have on them now, carry case and the heavy duty red carry case.
