When you think of high-performance headphones, you think of Sennheiser. The IE 100 PRO In-Ear Monitoring Headphones are no different, featuring a 10mm dynamic broadband transducer for high-resolution sound reproduction with warming tones. They utilise the same rugged connector that was originally developed for IE 400 PRO and IE 500 PRO headphones, as well as reinforced ear hooks for maximum comfort. The IE 100 PROs consist of an ergonomic earmold design with a stylish flat profile - allowing you to wear these in-ear headphones for long periods with minimal discomfort. Further to this, Sennheiser have been able to reduce acoustic stress by focusing upon the accurate, dissonance-free reproduction of audio. This means that even at maximum volume levels, you are guaranteed high-quality sound on the road, in the studio, and on the stage. The IE 100 PROs are available in black, clear, and red.

Dynamic Drivers

It is lesser known that a lot of in-ear monitoring systems use a multi-driver solution that is found in most hearing aids. The IE 100 PROs, however, utilise a next-generation single dynamic driver. This means that the frequency range is uninterrupted and creates a more ‘well-rounded' sound - further expanding the frequency spectrum. There are also no distortions due to the specially designed diaphragm, even at maximum sound levels. Further to this, phase issues and dissonances in the inner ear are precluded.

Performance Quality

The IE 100 PROs bring an advanced driver system to the ears of musicians, sound engineers and DJs. They are incredibly reliable, with Sennheiser reinventing the stage-compatible cabling to include a unique internal cable duct. By providing three sizes of earplugs, they are comfortable for every auricle. Whether you are a singer, guitarist, sound engineer, TV producer, stage director, or a DJ - the IE 100 PROs are the in-ear monitoring headphones for you.

Can you use these in-ear monitoring headphones as an average listener?

The Sennheiser IE 100 PROs work well as standalone in-ear headphones. They produce high-quality audio, more bass, better clarity, and a higher range of frequency than an average pair of earbuds.

What use do musicians have for in-ear monitoring headphones?

They produce only the sound that you really need to hear such as vocals, your guitar, drums etc. By doing so, the surrounding noise is reduced and you are provided with better overall clarity with a higher range of frequency.
