Verdict

The Harman Kardon CL (Classic) is an on-ear, closed-back headphone featuring 40mm drivers with a unique baffle design for extended bass, delivering a frequency response of 16Hz – 20kHz and a sensitivity of 119 dB/mW at 32 Ohms. Its industrial aesthetic is defined by a sandblasted steel frame, 2D swivel hinges, and magnetically attached memory foam ear pads, all weighing approximately 195g for lightweight portability. Key advantages include its user-interchangeable metal headbands (available in small and large sizes), an Apple-certified detachable cable with an integrated three-button remote, and a warm, balanced sound profile with exceptional midrange clarity. Notable drawbacks include the use of a non-standard 2.5mm connection on the ear cup side, potential discomfort for users with glasses or during very long listening sessions, and a lack of active noise cancellation.

What customers like about Harman Kardon Cl?

  • Premium industrial design with sandblasted steel and leather accents
  • Rich, punchy bass performance without being overwhelming
  • Clear and articulated midrange, making it excellent for vocals and jazz
  • Lightweight build with high-quality memory foam ear pads for comfort
  • User-replaceable parts, including magnetically attached ear pads and a detachable cable
  • Includes two exchangeable headbands (small and large) to ensure a better fit

What customers dislike about Harman Kardon Cl?

  • Rolled-off treble which can lack 'sparkle' and high-frequency detail for some genres
  • On-ear design may become uncomfortable during long listening sessions for users with wider heads
  • Uses a less common 2.5mm to 3.5mm cable, making generic replacements harder to find
  • Older faux leather material on the headband and pads is prone to peeling over time
  • Not a traditionally adjustable headband; users must physically swap the metal band for a different size
  • Lacks the extreme sonic detail and 'air' found in more expensive audiophile headphones
