Successor to the popular IE 40 PRO, the Sennheiser IE 100 PRO Wireless In-Ear Monitoring Headphones combines the black 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.

Precise In-Ear Sound    10mm Dynamic Single Drivers    Includes 3.5mm and Bluetooth Cables    Up to 26 dB of Passive Noise Attenuation

The IE 100 PRO is engineered with a 10mm dynamic single-driver design. The frequency range does not have to be split up into frequency bands as with multi-driver earphones. Distortion, phase problems, and dissonances in the inner ear are greatly reduced (or eliminated), resulting in a harmonious and powerful sound.

For safe monitoring in loud environments, the IE 100 PRO provides up to 26 dB of passive noise attenuation, reducing ear fatigue and allowing you to clearly hear your music without distracting ambient noise. This is achieved by using the pair of medium memory foam ear adapters, which expands to perfectly fit your ear canal—ensuring perfect acoustic sealing with the added benefit of enhanced bass reproduction.

The IE 100 PRO's compact design permits a lightweight construction, which, thanks to the accompanying silicone and memory foam adapters, can be individually adjusted to fit you perfectly.

• Built-in microphone and remote for call and music control
• Lightweight and durable neck-band design with reinforced ear hooks
• aptX Low Latency ensures perfect synchronization with video
• Up to 10 hours of battery life for all-day listening

The IE 100 PRO also comes with a black 4.3' detachable, straight, 3.5mm Y-cable that features reinforced ear hooks. A proprietary cable ducting with the connection inside the ear mold reduces risk of cable breaks. For a more discreet look, you can substitute the Y-cable with the IE PRO Mono Cable, a one-sided mono cable (available separately).
