What reviewers said
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
