Review on Top-quality CCA CKX In-Ear Monitors: 6BA+1DD HiFi Earphones with Zinc Alloy Shell and 0.75mm Cpin Wired Connection (No mic, Silver) by Lauren Miller

By far the smallest IEMs I own, these things definitely beat their price tag. Impressive bass and solid mids, but highs can be a bit sharp and tiring for those sensitive to treble. The mids and highs aren't as clear as I've heard from IEMs using more balanced premium armatures, and the bass, while incredibly powerful, lacks transient mobility, so it's not as detailed as it could be. Despite all this, they remain in my arsenal due to their incredible comfort and more than acceptable sound quality.
