Sennheiser has refined its technology to offer simple and intuitive settings that enhance speech intelligibility and reproduce the slightest details of your favorite music. The exceptional sound can be fully personalised to your hearing: simply choose the most adapted setting from the 7 profiles available to optimise your sound experience. The left/right balance control allows you to adjust the volume in each ear. The RS 195 also gives you a choice of listening modes. The "Speech Mode" reduces background noise and enhances speech intelligibility, while the "Music Mode" reproduces music with an increased dynamic range to perfectly preserve the sound image.
