Product details

Upgrade your Sennheiser listening experience

Refresh your desktop or living room setup with the NewFantasia Replacement Audio Upgrade Cable. Meticulously engineered to pair with a broad range of Sennheiser and Massdrop headphones, this 9.9-foot cord offers a balanced, easy-to-handle upgrade from aging stock cables. The result is a cable that feels sturdy yet soft to the touch, designed to stay comfortable through extended listening sessions. While it won’t transform every track, users may notice a more organized signal path and a clean, consistent connection that stays put during casual use or focused listening.

Key features

  • Premium wire construction with independent shielding for left and right channels, helping maintain channel separation.
  • Soft outer wrap with an OFC inner conductor for efficient signal transmission and a comfortable touch.
  • Length: 300 cm (9.9 ft), offering flexible placement from desks to couches without pulling on the headphones.
  • 3.5 mm male plug with a 6.35 mm adapter, enabling straightforward compatibility with many headphone amps and sources.
  • Compatible with a wide list of Sennheiser models (HD650, HD600, HD580, HD660S, HD58X, HD565, HD545, HD535, HD525, HD265) and Massdrop HD6XX.
  • Headphones are not included in the package; cable ships as a standalone upgrade solution.

What you get and how it helps

  • 1 replacement cable designed to replace worn or damaged stock cords, with a focus on reliability and durability.
  • A long and flexible length that supports varied seating arrangements, from desk setups to lounge listening.
  • A solid build that remains comfortable over long sessions, reducing handle fatigue while you enjoy your music or dubs.

Real-world scenarios

  • Desktop listening stations where a longer cable helps you move freely without pulling on the headset.
  • Living room setups with a nearby headphone amplifier where a single cable can cover the distance.
  • Bridging multiple Sennheiser models in a shared setup for testing and comparison without swapping cables between listens.
