Moondrop CHU II DSP
The Moondrop Chu 2 IEMs deliver impressive sound quality for their low price, with clear treble, detailed mids, and punchy bass when properly fitted. Build quality is solid with a metal housing and detachable cable, though the cable's ear hooks are weak and the dust filter may degrade after a few months. Some users experienced intermittent crackling or connection issues, but overall these are highly recommended for audiophiles on a budget.
