A Single Dynamic Driver

The IE 100 PRO uses a 10 mm dynamic broadband transducer for its monitoring design. Sennheiser specifies a frequency response of 20 Hz to 18 kHz and a 20-ohm impedance. These figures provide a useful reference when comparing the model with other in-ear monitors and the headphone output you plan to use as part of your audio setup.

Clear Housings, Article 508941

The Clear version is identified by Sennheiser article number 508941, distinguishing it from the black and red versions of the family. Its transparent housing gives the earpieces a particular appearance while retaining the IE 100 PRO monitoring platform. Select the model by its exact article and fit requirements when arranging the in-ear accessories for your own setup.

Detachable Black Cable

The supplied black cable detaches from the earpieces, providing a replaceable connection arrangement. Use the supported cable connections and route the cable around your monitoring position, keeping the earpieces and cable together when packing the set away. The detachable construction is a practical detail to compare alongside the driver type, housing shape and included ear-adapter options.

Foam and Silicone Adapter Choices

Foam and silicone ear adapters are included so you can select the fit that works with your ears. The adapter and its placement affect the seal and the way the earpiece sits. Try the supplied options and follow the manufacturer’s fitting guidance, then keep the selected pair in place when comparing the sound with your regular monitoring source.

Set Up the Monitoring Path

Connect the wired earphones to an appropriate headphone output and set a comfortable listening level. The analogue cable carries listening audio, leaving microphone and instrument recording to the connected audio equipment. Choose the supplied ear adapters around the fit you need for a stable monitoring position.
