Mark2410 has posted a review of the Echobox Finder X1 IEM on Head-Fi. He liked the X1 and expects it to be one of his reference IEMs for reviews. I purchased one as part of the Explorer X1 DAP Kickstarter. The Finder was ~$70 and came with 3 months of free Tidal so basically it was nearly free. I agreed with Mark2410’s conclusions but I would add that for me the Finder is very comfortable.
