What reviewers said

AKG K240

The AKG K240 is a wired, semi-open studio headphone with a classic design and a spacious, natural sound that shines in quiet environments. Its 55-ohm impedance makes it fairly easy to drive, but its lack of noise isolation and need for equalization to reach its full potential limit its appeal for casual or on-the-go listening.

  • Pro:Spacious and natural soundstage
  • Pro:Comfortable for long listening sessions
  • Pro:Detachable cable for easy replacement
  • Con:Requires EQ for optimal sound quality
  • Con:Leaks sound heavily and offers no noise isolation
