Many loudspeaker companies have diversified into headphones, but none has done so as spectacularly as Danish manufacturer DALI. Not only is the IO-6 a wireless design, it also incorporates excellent active noise cancelling, adding to its closed-back design three modes of cancellation. As if that wasn’t enough, it then adds best-in-class battery life to keep you listening longer – up to 30 hours between charges, in fact. Add to that a superbly powerful yet open and informative sound, and you have nothing less than a sensational début.
