@Sebastien Chiu Hey, looks like ALO posted some pre-owned stock on their site: https://aloaudio.deals/shop/polaris-ii-by-campfire-audio/ The cheapest one is $299, but may be only opportunity to get one as they’re rare for some reason.

The tuning switches are interesting! Will follow for impressions.

^ Good luck with potential purchase. I’m looking for a pair too (regrettably sold mine years ago), but they seem almost impossible to find at this point. I’d love to see CA release a v3... it was a great v-shape bassy IEM at a fair price point.

Best is subjective but the CA Andromeda (solid body) is my endgame / all-rounder. It handles gaming, movies and music perfectly for me.
