電視收聽系統由無線耳機與對應的無線音訊發射器組成。發射器必須連接至播放裝置(如電視或音響系統)的音訊輸出端。系統提供三種不同的傳輸選項:
紅外線無線耳機
若無線耳機透過紅外線接收音訊訊號,耳機與發射器之間必須保持直線視距。一旦視距中斷,音訊傳輸便會立即中止。
類比無線耳機
With analog transmission, there is always some background noise, but this is usually only perceptible during very quiet passages of music. Unlike many counterparts, the first-class Sennheiser sound can be enjoyed with little to no background noise. In addition, analog wireless headphones have a very long range: the connection is maintained even at distances of up to 100 meters from the transmitter.
數位無線耳機
相較於類比型號,數位無線耳機的優勢在於可同時使用多個無線連接而不產生干擾。由於類比無線耳機通常透過固定頻道傳輸,當家庭成員同時使用不同家庭娛樂設備搭配無線耳機時,便可能發生接收干擾。 在三種傳輸類型中,數位無線耳機提供最優異的音質表現。然而其傳輸距離遠遜於類比無線耳機:當使用者遠離發射器時,音訊訊號會立即完全中斷。
