Reviewer score 83% (normalized by Neofiliac)
Reviewers from whathifi have found:
IO-4s claim a whopping 60 hours of wireless listening time, double that of their noise-cancelling siblings. Charging time, thanks to the USB-C port, is just 2.5 hours from flat to fully charged. Stereo L comes through with noteworthy transparency throughout the frequencies; from the synth and low-level rhythmic riffs up into the keys.
Pros
  • Expansive, detailed sound
  • Excellent battery life
  • Comfortable fit
Cons
  • Dali’s noise-cancelling isn’t for everyone
