Sennheiser IE 100 PRO Black | Professional Stage Monitoring and High-Fidelity Listening Earphones

Born for the Stage, In-Ear Monitors Designed for Precise Monitoring

The Sennheiser IE 100 PRO Black is a professional-grade in-ear monitor from Sennheiser, featuring advanced 10mm dynamic driver broadband technology, offering a wide frequency response of 20Hz-18kHz and a sound pressure level of up to 115dB. Designed for musicians, DJs, and audio engineers, these earphones provide a precise, distortion-free sound monitoring experience in noisy stage or studio environments, with excellent passive noise cancellation effectively isolating external interference.

Compared to many multi-driver monitoring earphones, the Sennheiser IE 100 PRO, with its innovative single high-performance dynamic driver, fundamentally avoids phase shifts and harmonic distortion that can arise from multi-driver crossovers, achieving a more natural and consistent full-range sound reproduction. This makes it not only a reliable stage monitoring tool but also an ideal choice for music enthusiasts appreciating high-resolution audio.

Innovative Dynamic Broadband Driver: Equipped with Sennheiser's most advanced 10mm dynamic driver, delivering powerful, high-resolution, and warm sound, maintaining extremely low distortion even in high sound pressure stage environments, with clear and discernible sound details.

Ergonomic Comfortable Fit: The ultra-flat housing design and ergonomically shaped ear molds not only provide optimal sound isolation by fitting deep into the ear canal but also ensure extreme comfort and stability for long periods of wear, preventing them from falling out even during dynamic stage performances.
Excellent Passive Noise Cancellation: Through its snug in-ear design and included multi-sized silicone and memory foam ear tips, it provides up to 26dB of passive ambient noise isolation, allowing you to focus on the monitored audio content in any environment.
Detachable Cable Design: Features a patent-pending break-resistant cable connector and internal cable duct, ensuring a robust and durable structure. The detachable design allows users to easily replace cables, significantly extending the earphones' lifespan, and is also compatible with the IE PRO BT Bluetooth module.
