IE 100 PRO Wireless In-Ear Headphones (Red)

Product Description

Successor to the popular IE 40 PRO, the Sennheiser IE 100 PRO Wireless In-Ear Monitoring Headphones combines the red IE 100 PRO earphones with the IE PRO BT Bluetooth Connector. They wirelessly connect to your iOS/Android mobile device or macOS/Windows computer via low-latency Bluetooth 5.0 technology for perfect synchronization with video. Offering an accurate listening experience and high wearing comfort, the earphones are equally well-suited as everyday companions for audiophiles on the go or as professional monitors for musicians, DJs, and sound engineers performing live or producing in the studio. Support for SBC, aptX, aptX LL, and AAC codecs provides sonic quality that meets the demands of discerning listeners.

The IE PRO BT Bluetooth Connector features an in-line remote to control calls and music playback and a built-in microphone for calls and streaming. An internal lithium-polymer battery provides up to ten hours of continuous playtime for enjoyable, all-day listening. Use the included USB Type-C to Type-A cable to recharge the battery in up to 2.5 hours.

The IE 100 PRO's 10mm single dynamic drivers deliver a wide 20 Hz to 18 kHz frequency response and a well-rounded, warm sound that's powerful and nuanced, even on loud stages. Whether used at low or high sound-pressure levels (up to 115 dB SPL), your audio remains distortion-free and clearly defined—reducing ear fatigue during extended listening sessions.

Suitable for the rigors of stage use, the rugged IE 100 PRO Wireless also come with a 4.3' detachable cable for wired operation. Equipped with a 3.5mm jack, the cable enables you to use your earphones with wireless IEM bodypack receivers, mixers, and headphone amplifiers.

The compact housings are light (at 5.6 oz) and feature an ergonomic earmold design with a flat profile that provides a secure fit and comfort during prolonged use. The included pair of medium-size foam ear adapters adds up to 26 dB of passive noise attenuation, keeping extraneous sounds out and allowing you to focus on your music.

The IE 100 PRO Wireless is also supplied with three pairs of silicone ear adapters, a cleaning tool, and a soft protective pouch.
