Headphones — Moondrop Horizon

The Moondrop Horizon is a wired open-back headphone, fitted with dual 3.5mm sockets so the lead can be balanced or single-ended. Moondrop built its name chiefly on in-ear monitors, and the Horizon is one of its full-size over-ear models, the open-back option in the brand's over-ear headphone range.

Key specs that matter

Moondrop rates the frequency response from 20 Hz up to 34 kHz, reaching well past the usual limit of human hearing. Sensitivity is high at 109 dB per milliwatt, with a nominal impedance of 32 ohms.

Engineering and use context

Because the back of the earcup is open, the Horizon gives no isolation from ambient noise and lets its own output spill into the room. That makes it a headphone for quiet home listening rather than shared spaces or a noisy commute.

Pairing

A load this easy, combined with that sensitivity figure, lets a phone or portable player drive the Horizon without strain, while a dedicated headphone amplifier adds headroom for critical listening.

Alternatives

The Moondrop Para 2 is the closed-back counterpart, trading the open design for isolation.
