Sennheiser IE 100 Pro Red B-Stock

Each IE 100 Pro unit comprises a single dynamic broadband transducer with a diameter of 10mm, eliminating the need for multiple frequency subranges. This cutting-edge technology from Sennheiser is responsible for the headphones' characteristic powerful and precise sound. The driver is always active, reproducing the audio signal without distortion even at high volumes, and thus reducing acoustic stress factors. The optimised shape of the earpieces also reduces external noise, which is particularly helpful on stage. The silicone and foam ear tips included provide additional noise exclusion if desired, and the cable connection is extremely secure too – users will be glad it's there every time they wear these headphones, whether they're out jogging or performing live on stage.

In June 1945, Prof. Fritz Sennheiser founded the Wennebostel Laboratory, which initially produced measuring equipment. Commissioned by Siemens in 1945, the young company developed the MD-1 microphone, which was launched in 1946. After the development of further microphones, the company was renamed Sennheiser Electronic in 1958. Two years later, Sennheiser introduced the MD 421 dynamic microphone, which is still in production today and still held in high esteem by many sound engineers. Further groundbreaking developments, such as the HD 414 headphones and the classic MD 441 microphone, hugely enhanced the company's international reputation, eventually making Sennheiser one of the leading manufacturers of microphone and headphone systems in the world.
