A hand-built upgrade cable for Sennheiser HD 600 series headphones with 2-pin connectors. Suitable for Sennheiser HD 600, 650, 660S & 6XX. Every cable is made to your spec. Choose the length, the y-split length, the sleeve colours, and the amplifier-end termination to match your source.

Durable nylon weave covers hand-braided OFC copper. Reinforced strain relief protects the points where the cable meets the connectors. Your choice of amplifier-end terminations from audiophile and professional-grade manufacturers, including Neutrik, Viablue, Furutech and Amphenol. As standard, the y-split is finished with our own splitter, designed in-house and CNC-machined from aluminium, then sandblasted and anodised.

Assembled and soldered by hand, then thoroughly tested before it leaves the bench.

Hand-built to order in London. Shipped in 100% recycled and recyclable packaging with minimal branding. To keep it at its best, gently coil when not in use and wipe with a damp cloth to clean.

    Big upgrade over my last, similarly priced cable.

  3. Samuel Mills

    Very nice cable, you can immediately tell it is quality. Feels like the soundstage has opened up a bit too!

  4. Tom Fischer

    The build quality is excellent. Truly great craftsmanship. Shipping to Hamburg faster than expected. Will purchase another soon.

  5. Sam

    The HD 650s should really ship with a cable of this quality! I wanted a little change that wasn’t on the product page, and cxnnected made it happen. Will recommend to friends looking for quality headphone cables.

    This is my endgame cable, the extra thick cable looks amazing, and the sound quality (to my ears) is comparable to other more expensive (read:exotic) cables I own.

    Un beau câble pour un Sennheiser HD600. Très bien construit, belle finition. Les connecteurs s’insèrent facilement dans le casque ce qui est appréciable. Augmente de manière très significative la sonorité du HD600. Meilleur que le câble d’origine. Une belle définition, plus de basses, beaux médiums et plus de douceur dans les aigus. J’utilise le casque HD600 et le câble Cxnnected avec un ampli à lampes xDuoo TA-26S et un lecteur Denon DCD-1700NE (câbles Isotek et Sommercable Epilogue RCA).

    Built like a tank!

  9. Hudson

    Miles better than the standard cables.

    Lots of custom options and they feel and look very high quality.

    Audio quality is great.

    Will be coming to this store for all my future cables.

    Really nice upgrade from a stock Sennheiser cable. Not sure if the sound is better, but I simply enjoy the excellent build quality cable.
