Shure Se 112

A "Sound Isolating" In-Ear Designed for Everyday Listening

The 12 belongs to the family of closed in-ear earphones designed for mobile use: an approach that favors passive isolation and simplicity to achieve consistent sound in transit, open offices, or on the street. Rather than relying on electronic processing, its principle is based on ear fitting and a closed design to naturally limit ambient noise intrusion.

In this logic, the 12 relies on a reliable formula: dynamic driver, fixed cable, 3.5mm mini-jack connector, and essential accessories. A relevant choice for those who want an effective, easy-to-use in-ear without special configuration.

For Whom and For What: Mobility, Comfort, and Immersive Listening

These earphones are aimed at users who listen for long periods and often: daily commutes, work, studying, travel, or simple listening at home when isolation is desired. Thanks to the announced attenuation of up to 37 dB, you better enjoy nuances at low volume and avoid the temptation to raise the volume to "cover" the environment.

The closed in-ear format suits both podcasts and modern bass-rich playlists. The three sizes of supplied ear tips allow adjustment of comfort and isolation: a good fit improves bass, stability, and the sense of space.

Technologies and Highlights: Isolation, Dynamic Driver, and Simplicity

Sound Isolating: Less Noise, More Details

Sound Isolating technology aims to prevent external noises from interfering with listening. The result: better clarity of voices and instruments, more immersive listening, and a more consistent experience from place to place. This is a major asset in noisy environments, where isolation often makes all the difference.

Dynamic Micro Driver: Present Bass and Versatile Listening

The 12 is equipped with a single dynamic micro driver. This type of design is appreciated for its lively rendering and ability to deliver solid low frequencies while remaining pleasant during long sessions. Combined with an impedance of 16 ohms and a sensitivity of 108 dB SPL/mW at 1 kHz, it is suitable for common mobile sources without requiring dedicated amplification.

Fixed Cable and Mini-Jack Connector: Robust and Direct

The fixed 127 cm (black) cable favors simplicity: plug in and listen. The gold-plated 3.5mm stereo mini-jack connector ensures a reliable connection with the majority of portable devices and computers. The whole is designed for daily use without constraints, with a velvet drawstring pouch for transport.
