Sennheiser IE 100 PRO Wireless Core Technologies and Features

Professional Single Dynamic Driver Technology: Built-in with an advanced 10mm dynamic wideband driver, delivering powerful and precise monitoring sound quality. Unlike traditional multi-driver systems, the single dynamic driver design avoids phase distortion and internal resonances, reproducing warm, distortion-free, and clear audio even at high sound pressure levels.

One device, two uses, flexibly adapting to various scenarios.
AptX Low Latency Bluetooth Transmission: The IE Pro BT connector utilizes Bluetooth 5.0 technology and supports AptX™ Low Latency codec, ensuring perfect audio and video synchronization. Whether watching videos or playing mobile games, you can enjoy a lag-free immersive experience.
Ergonomic Comfortable Fit: After studying hundreds of ear shapes, Sennheiser developed an extremely flat and lightweight earphone housing. Coupled with an over-ear design, it provides a stable fit, remains comfortable for long-term use, and offers excellent passive noise isolation.

Sennheiser IE 100 FAQ

Q：Can the Sennheiser IE 100 PRO Wireless Transparent be used with a wired connection only?

Q：What are the differences between IE 100 PRO and IE 40 PRO?

▼

A：The IE 100 PRO is the successor to the IE 40 PRO. Both have similar driver technology, but the IE 100 PRO has improved connector specifications, making it compatible with the higher-end IE 400/500 PRO series for greater accessory versatility.

Q：Is there a difference in sound quality between the IE 100 PRO Wireless's Bluetooth and wired modes?

▼

A：Wired mode provides the most lossless sound quality. While Bluetooth mode involves compression, it supports AptX encoding, which already delivers high-quality wireless audio close to CD quality, making the difference negligible for daily listening.

A：Yes. Its over-ear design and lightweight body provide a very secure fit, suitable for most non-strenuous sports scenarios. However, please note that it is not advertised with a high waterproof rating.
