Shure SE425-CL Professional Sound Isolating Earphones

The Shure SE425-CL Professional Sound Isolating Earphones are wired in-ear monitors designed for detailed listening, personal monitoring, and everyday playback. Their sound-isolating fit helps reduce surrounding noise so listeners can focus on program material without relying solely on higher volume. They are a practical choice for musicians, engineers, commuters, and listeners who prefer a secure wired connection.

Dual balanced-armature drivers provide the SE425 with accurate, natural sound across a specified 20 Hz to 19 kHz frequency range. The design is intended to present detail clearly for music playback and onstage monitoring. With 109 dB SPL/mW sensitivity and 22-ohm impedance at 1 kHz, the earphones are suited to compatible portable and professional headphone outputs.

The low-profile earpieces route the cable over the ear to help keep the earphones stable and keep cable movement out of the way. A proper seal is important to both isolation and bass response, so Shure includes several sleeve styles and sizes. This lets each user choose a fit based on comfort, retention, and the level of isolation needed.

A detachable 64-inch clear cable uses gold-plated MMCX connectors with a lock-snap fit and 360-degree rotation. The cable can be replaced if it is damaged or swapped for a compatible Shure accessory cable. Its 3.5 mm stereo mini plug connects directly to many headphone outputs, while the included threaded adapter supports 6.35 mm connections.

The SE425-CL can serve as a focused listening upgrade for a portable player, headphone amplifier, audio interface, or compatible in-ear monitoring receiver. It does not require an external amplifier for basic use, but source equipment must provide a compatible 3.5 mm headphone output or an appropriate adapter. A premium carrying case is supplied for storage and transport.

Key Features

• Dual Balanced-Armature Drivers: Separate drivers deliver detailed, accurate sound reproduction.

Design & Installation

The SE425-CL uses a discreet in-ear form factor with clear components, an over-ear wireform cable arrangement, and detachable gold-plated MMCX connectors. The connector system has a lock-snap fit and allows rotation at the earpiece for positioning comfort. The supplied premium carrying case helps protect the earphones and accessories between uses.

Choose the sleeve that creates a comfortable, secure seal, then route the cable over the ears and use the cable cinch to manage slack if needed. Connect the 3.5 mm plug to a compatible headphone jack, or attach the supplied 6.35 mm threaded adapter for compatible professional equipment. For best low-frequency performance and isolation, reseat the earphones or try another sleeve size if the seal feels loose.
