What reviewers said
Hidizs ST2 PRO
The Hidizs ST2 PRO is a wired single-dynamic-driver IEM that delivers a powerful, bass-forward sound with solid punch and rumble, making it a good pick for those who prefer energetic tuning. However, its bright treble and recessed vocals mean it's not ideal for vocal-focused or clarity-seeking listeners, and it offers limited isolation. Priced affordably, it provides decent value with a comfortable cable and USB-C connectivity, though its output may be too intense for some.
- Pro:Strong bass impact and rumble
- Pro:Energetic, engaging sound signature
- Pro:Comfortable detachable cable
- Con:Vocals can sound recessed
- Con:Treble may become fatiguing
- Con:Limited passive isolation
Moondrop Aria
The Moondrop Aria is a wired in-ear monitor that delivers a balanced, neutral-leaning sound with a touch of warmth and extra bass punch, making it a strong performer for its price. It's easy to drive from most devices thanks to its high sensitivity and 32-ohm impedance, and it offers solid build quality with a removable 2-pin cable. However, it lacks features like noise cancellation and controls, and its isolation is only average, so it's not ideal for noisy commutes.
- Pro:Excellent tonal balance with natural midrange timbre
- Pro:High sensitivity makes it easy to drive from phones
- Pro:Solid build quality with removable 2-pin cable
- Con:Average isolation, not suited for loud environments
- Con:Cable is prone to tangling and transmits some noise
- Con:No inline controls or microphone
