Image © CrinEarThe Project Monolith is a limited-edition dual dynamic driver IEM with a monolithic brass shell plated in 18K gold, featuring a bass-forward tuning and the debut of CrinEar's MDM acoustic platform. It is limited to 999 units worldwide.
The CrinEar Project Monolith is a limited-edition wired IEM engineered for bass enthusiasts, pairing a hybrid dual-driver setup with a brass build to deliver powerful low-end while keeping mids and highs natural. Its niche, bass-forward tuning and 999-unit production run make it a collector's piece rather than an all-rounder, though comfort is a standout strength. With a 4.4mm balanced connection and a wide frequency range, it targets listeners who prioritize sub-bass impact over neutrality.

Video reviews we found, each condensed to its verdict. They do feed the HearWiki score, at a measured weight below what a published written review carries.
21:20The reviewer finds the CrinEar Project Monolith to be a well-executed IEM with a unique brass construction that uses the shell itself as the acoustic chamber. It delivers a solid, full-bodied sound with a tasteful bass boost that doesn't overwhelm, though it's not for bassheads. The main drawbacks are the very thick cable and the heavy, dense build, but overall it's a good value at $400.
