Sennheiser IE 100 PRO In-Ear Monitoring Headphones (Red)

The Sennheiser IE 100 PRO in-ear monitoring headphones are a professional-grade solution for musicians, sound engineers, and DJs who need accurate, distortion-free monitoring on stage, in the studio, or on the go. As the successor to the popular IE 40 PRO, this model refines performance, comfort, and versatility to meet the demands of real-world use.

Whether you're mixing live sound or monitoring a studio session, these earphones deliver clear, balanced audio and a comfortable, secure fit even during extended wear.

Precise Sound for Live and Studio Use

Equipped with a single 10mm dynamic driver, the IE 100 PRO delivers a rich and natural sound profile without relying on multiple drivers. This design reduces phase inconsistencies and distortion across the 20 Hz to 18 kHz frequency range, giving you powerful lows, detailed mids, and smooth highs, even at high sound pressure levels up to 115 dB SPL.

The result is a warm and balanced listening experience that holds up in loud environments without overwhelming your ears or sacrificing clarity.

Comfortable, Lightweight Fit for Long Sessions

With a compact housing that weighs just 5.6 oz, the IE 100 PRO is built for all-day comfort. Its ergonomic earmold design ensures a snug and secure fit that stays in place, even during movement-heavy performances. The included silicone and memory foam ear adapters in multiple sizes allow for a tailored fit, helping you stay focused on your mix without discomfort or adjustment.

Noise Isolation That Lets You Focus

The IE 100 PRO includes medium-size foam ear adapters that provide up to 26 dB of passive noise attenuation. This helps block out ambient noise so you can hear every detail of your performance clearly, even on loud stages. The tight acoustic seal also enhances bass response while reducing ear fatigue during long monitoring sessions.

Durable, Detachable Cable for Everyday Use

Designed to withstand the demands of live performance, the IE 100 PRO features a 4.3-foot detachable straight Y-cable with reinforced ear hooks for a secure and reliable connection. The 3.5mm jack offers wide compatibility with wireless in-ear monitor systems, mixers, audio interfaces, and mobile devices.

Sennheiser’s proprietary cable ducting system routes the connection through the ear mold itself, reducing the risk of cable breakage over time. For an even more discreet setup, the cable can be replaced with the optional IE PRO Mono Cable (sold separately).

Complete Monitoring Kit Included

Each pair of IE 100 PRO headphones ships with:

• Three pairs of silicone ear adapters

• One pair of medium memory foam ear adapters

• Cleaning tool

• Soft protective pouch

This all-in-one package ensures you're ready to monitor with precision and comfort right out of the box.
