The DALI IO-6 is a closed-back unit, designed to provide a high level of natural passive noise isolation (PNI). However, low frequency noise cannot be removed passively, which is why the DALI IO-6 employs the latest ANC technology to remove background noise.
The DALI IO-6 offers three different ANC modes that enable you to choose how much of the surrounding noise, you want to cancel out: ANC ON, ANC OFF and Transparency mode.
When ANC is activated, the IO-6 actively cancels low frequency noise - eg. in the shape of a repeating and rhythmic deep background rumble. Be it in the office, on an airplane, bus or train or when mowing the lawn.
When ANC is deactivated, you will still experience a high degree of isolation due to the sealed closure of the soft ear pads - providing a natural PNI.
The third mode, Transparency, bypasses the Passive Noise Isolation (PNI) by feeding external ambient audio into the headphone audio. The headphones effectively become one-way (out to in) acoustically transparent.
Removing the background noise helps you to relax and enjoy your favourite music whether it be at home or on the go. Along with reducing the annoyance of external noise, noise cancelling improves the audibility of music detail, meaning you can listen at lower volume – reducing the potential of long term hearing damage.
You can easily toggle between the three ANC modes with a dedicated button placed conventionally on the rim of the right ear cup - making it easy to acces even with gloves.
