What reviewers said

HiFiMAN HE 600

The HiFiMAN HE600 is an open-back planar headphone that modernizes the classic HE6 concept with a lighter build and easier amplification needs, while retaining a clean, detailed, and balanced sonic character. It offers strong technical performance for its price, though its tight clamping force and slight shortfall in sheer tactility compared to its predecessor are notable trade-offs.

  • Pro:Clean, well-extended bass with good detail
  • Pro:Natural and articulate mids with smooth treble
  • Pro:More practical to drive than the original HE6
  • Con:Strong clamping force reduces comfort
  • Con:Not a full upgrade over the HE6 in depth and tactility
  • Con:Still requires decent amplification to shine

Sennheiser HDB 630

The Sennheiser HDB 630 is a premium wireless over-ear headphone that prioritizes audio fidelity above all else, pairing a detailed, balanced sound with strong adaptive noise cancellation. It offers an extensive feature set, including multi-device pairing, a transparent mode, and support for high-resolution aptX codecs via its included USB dongle. While its sound quality is a clear standout, its high impedance and specific tuning may not suit every listener, and its premium price reflects its niche focus on audiophiles who want wireless convenience without sacrificing performance.

  • Pro:Excellent, balanced sound with a musical midrange
  • Pro:Strong adaptive noise cancellation with transparency mode
  • Pro:Long 60-hour battery life and quick charge support
  • Con:High 480-ohm impedance may require more power than typical phones
  • Con:Noticeable sonic quirks in certain frequency ranges
  • Con:Premium price tag for a niche audience
