The Moondrop Jiu could represent the budget IEM market’s next big leap thanks to its integrated DSP. This technology will allow manufacturers to squeeze out even better tunings from entry level drivers, adding to the amazing progress the market has made in recent years. If you already have the Chu, getting the Jiu is not a must. But if you’re curious about integrated DSP, you should give the Jiu a listen.
My full review, with a subjective comparison to the Moondrop Chu, frequency response measurements, and additional images, is available on my blog and in my HiFiGuides thread.
