Sennheiser IE 100 PRO Wireless – Professional In-Ear Monitors with Bluetooth and Wired Flexibility

The Sennheiser IE 100 PRO Wireless In-Ear Monitoring Headphones are the ideal choice for performers, producers, and discerning listeners who want high-fidelity sound, long-wearing comfort, and the freedom of both wired and wireless connectivity. As the successor to the widely loved IE 40 PRO, this version combines the precision-built IE 100 PRO earphones with the IE PRO BT Bluetooth Connector, offering studio-grade sound monitoring with the convenience of Bluetooth.

Whether you're on stage, in the studio, or listening on the go, these in-ear monitors provide the quality and versatility to meet professional demands.

Studio-Quality Sound Anywhere You Go

Equipped with a single 10mm dynamic driver, the IE 100 PRO delivers a powerful, well-rounded sound across a wide 20 Hz to 18 kHz frequency range. Unlike multi-driver systems, this single-driver design ensures your audio remains coherent and distortion-free, even at high sound-pressure levels up to 115 dB SPL. The result is a natural and detailed listening experience with reduced ear fatigue, ideal for extended use.

Low-Latency Bluetooth for Real-Time Monitoring

The included IE PRO BT Bluetooth Connector features Bluetooth 5.0 with support for SBC, AAC, aptX, and aptX Low Latency, allowing you to wirelessly stream high-quality audio from iOS, Android, macOS, or Windows devices. Thanks to aptX Low Latency, audio stays perfectly in sync with video, making these monitors a reliable choice for content creators and musicians needing real-time feedback.

An in-line remote and microphone lets you take calls and control music effortlessly, while the built-in battery offers up to 10 hours of continuous playback. Recharge via USB-C in just 2.5 hours, and enjoy a full day of uncompromised audio.

Designed for Long Listening Sessions

The lightweight and ergonomic housing is crafted for all-day wear. Weighing only 5.6 oz, the IE 100 PRO fits comfortably with a flat-profile, secure design that minimizes pressure during long sessions. Included memory foam ear adapters expand to your ear canal for a custom seal, providing up to 26 dB of passive noise attenuation. This blocks unwanted background noise and enhances bass response naturally, ideal for safe monitoring in loud environments.

Also included are three sizes of silicone ear adapters, allowing you to find the perfect fit for maximum comfort and sound isolation.

Rugged and Reliable for Stage Use

The IE 100 PRO is built for the demands of live performance. A detachable 4.3-foot Y-cable with a 3.5mm plug comes included for wired operation, making it compatible with bodypack IEM receivers, mixers, and headphone amps. Reinforced ear hooks and proprietary cable ducting help prevent cable strain and breakage, ensuring long-term durability. For a lower-profile option, the earphones are also compatible with the IE PRO Mono Cable (sold separately).

Compact, Versatile, and Travel-Ready

Whether you're a touring musician, a mixing engineer, or an audiophile on the move, the IE 100 PRO Wireless system adapts to your workflow. The included soft carry pouch, cleaning tool, and USB-C to USB-A charging cable make it easy to keep everything protected and ready to go.
