Sleek. Easy to control. Listening without strain.

Motion® fits comfortably and discreetly behind your ear and comes in models to suit every hearing need. Easy to adjust and control, it’s packed with functionality that lets you hear without exertion all day long. Simply relax and enjoy hearing again without the strain.


Comfortable, easy to use, and robust.

Robust enough to withstand the rigors of daily life, Motion is IP67-rated to resist moisture, dust, and dirt. Choose between an earhook or ThinTube to maximize hearing and wearing comfort.

Enjoy life’s true sound.

Holding a conversation requires concentration and effort in places with high levels of ambient noise. Straining to hear voices in crowded restaurants or at parties is tiring, even for people with normal hearing.

Motion relieve this with the help of the SPEECH function, which continuously monitors what you are listening to and singles out the dominant speaker. Now you don’t have to struggle to hear over interfering voices and background noise. As a result, hearing requires less effort and is less tiring, all day long.


Motion lets you enjoy family time again.


Scenario 1: Breakfast.

Your family is sitting around the breakfast table gabbing about the day’s plans. Voices reverberate around the kitchen. Forks and spoons clink against plates in the background. Motion brings outstanding performance to the table to make sure you don’t miss a thing. Its advanced automatic SPEECH function singles out the speech while simultaneously engaging SoundSmoothing™ to reduce distracting background noise.

Thanks to Motion, you hear what matters with ease.


Scenario 2: Coffee break.

Imagine you’re enjoying the breeze outside a coffee shop with a friend, just watching traffic pass by. Motion rises to the challenge, employing its automatic SPEECH function to single out your friend’s speech while simultaneously engaging noise reduction and eWindScreen™ binaural to reduce wind noise and suppress the sound of cars. Now you’ll hear every word clearly.

Scenario 3: A time to celebrate.

At a lively party, your discussion is one in a crowd of conversations. Motion manages the situation with ease. Even after the celebration moves into a large ballroom, causing chatter to echo off the walls, Motion’s EchoShield program softens the reflected sound, so you can concentrate on having fun.


Scenario 4: Outstanding music fidelity.

Motion’s HD Music program was made to let you fully enjoy music again. Whether you’re listening to your favorite band at a concert, at home on your high-fidelity stereo — or you’re the one on stage performing — HD Music offers an optimized and superb entertainment experience.

Don't miss a word - even with a deaf ear

For people who can only hear on one side, listening can be extremely strenuous in many daily situations. Understanding speech is particularly difficult in noisy surroundings and can be very exhausting. Signia CROS/BiCROS hearing aids now offer an innovative solution for people with an unaidable hearing loss in one ear. Wireless technology helps them hear and understand every word again. In addition, it significantly reduces their listening effort.

People with a unilateral unaidable hearing loss are particularly challenged. Whether on the street, in the office, or talking with friends, sounds and voices are indistinct or not heard at all when they come from the “wrong” side. Constantly moving your head to try to hear better is strenuous and also not always possible (e.g., when driving). Above all, the ability to understand speech is severely limited. The new Signia CROS Pure device that wirelessly transmits the signals from the ear with hearing loss to the other ear can help.
