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
TRN ST2
The TRN ST2 is a budget hybrid in-ear monitor that delivers a punchy low end and a broad soundstage for its modest price. Its clean mids and defined bass make it appealing for certain listeners, though its upper-range tuning may come across as bright or harsh to some ears. It also includes a microphone and offers a light, comfortable fit with minimal cable noise.
- Pro:Strong bass presence and clear mids
- Pro:Wide soundstage for the price
- Pro:Lightweight and comfortable to wear
- Con:Upper mids and lower treble can sound splashy or fatiguing
- Con:Tuning may not suit all listeners
- Con:Build and accessories are basic for the price
