Moondrop SSR Beryllium Dynamic Driver In-Ear Earphone White

What the Moondrop SSR is

The Moondrop SSR is a wired in-ear headphone that uses a beryllium-coated dome diaphragm with a polyurethane suspension ring and a CCAW voice coil driven by an N52 magnet circuit. It terminates in standard 0.78 mm 2-pin connectors and ships with a silver-plated 4N-Litz OFC cable. The housing is cast from a single-piece liquid-metal alloy and secured with screws for structural rigidity. A patented triple-layer anti-clogging acoustic filter protects the driver from debris.

Listeners who want reference tuning

The SSR targets listeners who prefer an uncoloured presentation with undecorated bass and reference treble that stays faithful to the original recording. Its wired 0.78 mm 2-pin connection suits stationary or portable sources with a headphone jack or dedicated amplifier. Buyers who need Bluetooth connectivity, active noise cancellation or an inline microphone for calls should look at a different design, because the SSR provides none of those functions.

Cable, connectors and filter change daily use

The included silver-plated 4N-Litz OFC cable uses standard 0.78 mm 2-pin plugs, so the cable can be swapped for aftermarket options without proprietary adapters. The patented triple-layer anti-clogging filter reduces the risk of wax or dust blocking the sound bore, which helps maintain consistent volume balance between channels over time. The transparent, highly elastic jacket on the cable resists tangling and microphonics during movement.
