The Chu.was the first Moondrop product I purchased. Neutrally tuned? Perhaps. For me it is one of the most fatiguing pair of IEMs that is now collecting dust in a drawer after only a handful of sessions while I usually really enjoy to buy,.try and drive new IEMs.

Had no quality issues with them but was very much underwhelmed, even "for the price". No way that I am going to burn more of my hair cells on the LAN..
