The DALI IO-6 has been reviewed by Valentin Lefort on the blog section of SON-VIDEO.com:
"When listening to Michael Jackson's Off the Wall, the Dali IO-6 headphones are very dynamic. Each effect is perfectly rendered and stands out very well from the rest of the scene. The voice of the king of pop is extremely clear and perfectly placed. We are transported and cradled by the different arrangements. The snare drum beats the title and has never been so good."
"On the various tracks listened, the Dali IO-6 confirms its dynamic character. The bass is lively and knows how to be very present when the music requires it, without taking precedence over the rest of the instruments."
"We find a rich sound signature, detailed and very dynamic. The bass is present, without ever impinging on the rest of the sound stage, even when the volume is exaggeratedly pushed. The thick ear cushions and the padding of the headband ensure a great comfort of use, even after long hours of listening."
