earis® – 2.4GHZ Digital Wireless Headphones with Underchin Receiver
The transmitter
The earis® transmitter serves also as a charger forthe according receiver. It also features a further charging slot for a secondary receiver battery (available as accessory). The main control element is the selection buttonfor the five dynamic sound HS programs. The devices are already paired by default when delivered.
The underchin receiver
The light-weight earis® under-chin receiver is comfortable to wear and applies no pressure on the ears. Thespeaker arms are sturdy and the ear pieces are pivoted for aperfect fit to the ear canals. The speaker arms also activate the receiver when used, so the user does not need to worry about switching the receiver on or off. Thelarge shiny wheel-shaped silver volume control, which can deliver up to 122 dB (A), dominates the design of the receiver.
LEDs provide information on charging status, hearing profile selection and volume setting. A balance adjuster on the reverse side of the receiver allows to shift volume leftand right in order to compensate for one-sided hearing loss. earis® also features a communication amplifier function.
Switch to communication
The system can be switched to a amplified communication function. When activated, earis will pick up sound and speech within the environment and will amplify it over the speaker arms or the hearing component attached to the pocketreceiver.
earis memorizes the volume settings which were last used in both the audio transmission and the communication mode. So the user returns to the preferred volume he had last used, in whichever mode he chooses.
Dynamic Sound HS
Humantechnik has branded the main characteristic, which makes earis a top model in the premium class, as dynamic sound HS . This provides five dynamic audiological sound programs for different TV formats. The programs can be selected by simply pressing a button - they adjust the incoming audio transmission continuously to the best possible sound quality for its user. These programs are based on a sound-supporting algorythm, developed specially for people with impaired hearing at the Fraun hofer-Institute for Digital Media Technology IDMT in Oldenburg, Germany.
Exchangeable battery
The easily exchangeable battery lasts for up to 9 hours -with a charging time of only two hours. A secondary back-up battery (available as accessory) makes almost unlimited use possible.
