Nathan posted a review on Headfonia of the Echobox Finder with various detailed comparisons to the Grado GR10. There is also a post on Head-Fi comparing them to the Monster Miles Davis Trumpet IEM which I personally love. Actually, I loved these so much I purchased several of the Trumpets. Looking at their website it appears that Echobox will be launching their new DAP and X1 via IndieGoGo on Monday. No pricing but I would expect them to be well under $300 and likely around $100 but you never know.
