Raising the bar

Evolution Wireless Digital breaks the boundaries by providing more dynamic range than any wireless system currently on the market. Automatically securing the most reliable signal in a matter of seconds and scalable up 90 channels thanks to 56 MHz of tuning bandwidth, it’s easy to see why this wireless system is in a class of its own.

Equidistant Spacing – simpler than it sounds

Evolution Wireless Digital features an equidistant tuning grid previously only found in our flagship Digital 6000 and Digital 9000 wireless systems. Quality components with exceptional linearity eliminate intermodulation between EW-D transmitters, allowing frequencies to be equally spaced every 600 kHz alongside each other. This simplifies frequency coordination for wireless beginners and seasoned professionals alike, and also contributes to the system’s scalability and impressively high channel count.

The power of Bluetooth Low Energy puts full control right in the palm of your hand with the Sennheiser Smart Assist app. Take advantage of a remarkably fast automated setup, mobile access to every system setting and the added benefit of remote monitoring, all from the convenience of your Android or iOS device. Save time, save energy and perform with confidence.

HSP Essential Omni

Whatever you want to convey, the HSP Essential Omni neckworn microphone gives weight to your voice. Just as it pushes your speech forward, the device itself holds back from pressure and discomfort. Inconspicuous and lightweight, it is barely felt, even when worn for extended sessions. This also applies to its price, as the HSP Essential Omni won’t apply pressure on any budget.

Nothing else is needed to convince you

With the HSP Essential Omni, the name is also a philosophy: it compresses professional requirements relating to quality and function down to the essentials – for a substantially lower price. For this price it combines a high level of wearing comfort with a robust frame, brilliant sound with distortion-free transmission and an inconspicuous appearance with a light-weight design. The result is a professional headset microphone to suit any budget.

HSP Essential Omni. Focus on what’s really important.


Thanks to its continuously adjustable neckband, the HSP Essential Omni adapts perfectly to any head size or shape. Once adjusted, it is barely felt, as the optimally distributed lightweight design of only 25 grams exerts very gentle pressure. Furthermore, the microphone boom can be positioned on either the right or left side depending on the user’s preference.

Gives weight to every voice

The HSP Essential Omni features Sennheiser’s tried-and-true high-quality condenser KE 4 capsule. It is omnidirectional and achieves a clear, warm and distortion-free sound, even with very loud voices. Its patented umbrella diaphragm also provides reliable protection from moisture.

Inconspicuous and lightweight

All the components of the HSP essential Omni, such as the particularly slim microphone boom, have been kept as small as possible so as not to be noticeable during use. Select from both black and beige for easy concealment. Its lightweight, compact form factor is exceptionally robust and is designed for a long life-span. Should anything malfunction, the components of the HSP Essential Omni can also be easily replaced.

  • Newly developed KE 4 capsule provides warm nuances and better audio quality
  • Ability to handle maximum sound pressure levels for distortion-free reproduction in every application
  • Flexible and ergonomic neckband design adapts securely to a variety of head shapes and sizes
  • Gentle yet secure fit for maximum wearing comfort
  • Robust construction while simultaneously delicate and inconspicuous
  • Sweat resistant thanks to patented umbrella diaphragm and rubber sealing ring
  • Easy maintenance: high-quality mechanical structure; all individual parts can be replaced and ordered separately
