Sennheiser HD 600

Decades on, it is still one of the safest recommendations in wired hi-fi headphones, for listeners at a desk or in a quiet room.

90 out of 100

Excellent

Best for: Home listeners who want a proven reference sound

The HD 600 has been a reference point for open-back headphones since the late 1990s and remains in Sennheiser's lineup. SoundGuys still rates its sound quality and comfort highly, and nearly every part, from the cable to the earpads, can be replaced. Its 300-ohm impedance is high, which is worth considering if you plan to use it with a phone or laptop. As with any open-back design it offers almost no isolation, and sub-bass is light compared with modern planar and closed-back alternatives.

  • Comfortable for long listening sessions
  • Replaceable cable and earpads
  • Sells well below its $499.95 list price

What's not

  • High 300-ohm impedance
  • Weak sub-bass
  • Almost no noise isolation
