What reviewers said
Moondrop JIU
The Moondrop JIU is an affordable wired USB-C earphone that delivers surprisingly polished sound for its price, with a well-tuned dynamic driver and a DSP microphone for calls. It's a sensible pick for casual listeners who value simplicity, though its non-detachable cable and occasionally bright treble may deter some. Overall, it offers solid value within the still-narrow field of DSP-equipped budget IEMs.
- Pro:Excellent tuning for the price
- Pro:Good technical performance for a budget model
- Pro:USB-C connectivity with DSP mic for clear calls
- Con:Treble can be overly bright for some
- Con:Fixed cable cannot be replaced
- Con:Not an elite technical performer

The TRN ST1 Pro is a budget-friendly hybrid in-ear monitor that pairs a 10mm dynamic driver with an additional driver for a two-way setup. It includes physical tuning switches to adjust the sound signature, and its lightweight build makes it comfortable for extended listening sessions. Despite its low price, it offers a customizable and detailed audio experience for entry-level enthusiasts.
- Pro:Very affordable hybrid driver design
- Pro:Tuning switches for sound customization
- Pro:Lightweight and comfortable fit
- Con:Build quality may feel basic
