earis® – 2.4GHZ Digital Wireless Headphones with Pocket 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 pocket receiver
The earis® pocket receiver comes with the included inductive earis® neckloop, but it also allows the connection of a wide variety of commercially available hearing accessories via a regular 3.5 mm stereo jack socket,so other individually prefered accessories such as headphones, earphones or headsets may be used.
A clip on the back of the device serves to fasten the receiver to clothing. An eyelet is provided for the optionaluse with a carrying cord.
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.
