Sennheiser launches IE 100 PRO and IE 100 PRO Wireless, rounding off its portfolio of in-ear monitoring solutions


If music is your profession and your passion, then Sennheiser’s new IE 100 PRO Wireless in-ears are for you: They let you take the top-grade monitor sound you demand from the stage right onto the street thanks to the inclusion of a Bluetooth® connector that can be swapped with the cable when preferred. Listen to playlists, make calls or watch videos, while the AptX™ Low Latency codec ensures that sound and image are in perfect sync. The Bluetooth connector features a built-in microphone, remote for call and music control and a battery life of up to ten hours. Naturally, the IE 100 PRO is also available individually for stage work, where it surprises with some clever extras…

Precise monitoring and enjoyment of music too

When making music, more control means a better performance: As successor to the IE 40 PRO, the IE 100 PRO in-ears offer a natural, warm and utterly precise monitoring sound that allows you to fine-tune your performance with ease.

Thanks to the included silicone and memory foam ear tips, the in-ears adapt perfectly to your ear canals, coming as close as possible to custom ear moulds. This snug, comfortable fit is supported by a low-profile mould.

A reinforced ear-hook and detachable cable with patent-pending, break-proof connector give you the reliability you need during your performance. The package is rounded off by a cleaning tool and a soft pouch.

The in-ears are available in black, clear and red.

“When you choose the IE 100 PRO Wireless, you get an outstanding two-in-one solution,” says product manager Gunnar Dirks. “In addition to the standard accessories, the IE 100 PRO Wireless includes the IE PRO BT Connector – simply unplug the standard cable, attach the lightweight semi-wireless cable instead and enjoy great audio with all the freedom of a Bluetooth connection!” A USB-C cable, which fully recharges the Bluetooth connector in 1.5 hrs is included, too.

And now for the clever extras…

While the IE 100 PRO retains the same transducer and frequency response of its predecessor, it is now fitted with the same connector type and clever stage-proof internal cable duct as the IE 400 PRO and IE 500 PRO.

“Using one connector platform allows users to simply select their favourite cable regardless of the model they own,” says Gunnar Dirks. “For example, IE 500 PRO users can simply get themselves an IE PRO BT Connector to use their professional in-ears for wireless music enjoyment. Moreover, with the IE PRO Mono Cable, we’re adding a new solution for broadcasting.”

The new IE PRO Mono Cable is a twisted cable that offers excellent suppression of structure-borne noise. It can be used with the right or left earpiece, which gives a single-sided broadcast solution for live moderation, correspondents and ENG applications. With a stereo signal, the left signal will be transmitted.
