Blue Dragon Sennheiser Headphone CableVersion 3 (New!!)
This is the new Blue Dragon Headphone Version 3 headphone replacement cable for Sennheiser hD-800 ,HD-650 , HD-600 and HD-580 headphones and any other Sennheiser headphones that have the 2 pin connection system. Such as HD25, HD265, HD445, HD525, HD535, HD545, HD565, HD580, HD600, HD650, HD800.
We also use it for the Ultrasone, Sony Qualia, AKG Pro Series and any other headphone that uses a connector attachment System. This cable can also be hard wired to Grado's, AKG, Audio Technica etc etc...
This cable been designed to match the Silver Dragon Headphone cable but with a high purity copper conductor using the Ohno Continuous Casting Process. It has the same geometry structure as the Silver Dragon Version 2 only it uses UP-OCC pure copper.

The cable uses a 4 x 24AWG Teflon insulated stranded conductors using pure single crystallized UP-OCC pure copper with 7N purity 99.99998%.
Each conductor is made up of a special varying size stranding geometry. The copper stranding is mixed with Kevlar stranding to reinforce the conductor. Making it stronger overall and less prone to failure due to the harsh constant flexing a headphone cable receives.
The conductors are then surrounded by cotton and then a layer of Teflon tape.
The new version is now also shielded and placed in a polyethylene jacket for further protection.
The Version 3 is quieter than the Version 2 with no micro phonics.
The pin connectors are soldered to the conductors and then molded to the cable. The splicing method used by other cable companies using a stock Sennheiser cable's connectors is a poor method. And defeats the purpose of replacing the cable. That method requires you to once more send the signal through the poor quality conductors in the stock Sennheiser cable as well as through one more solder joint. Moon Audio, Cardas and Zu are the only three cable companies I am aware of that use a preferred method of headphone connection method
The wire is soldered to the connector with Cardas silver solder. The default 1/4" Plug is the Furutech FP-704(G). The default 1/8" plug is a Neutrik NYS231B. And the default XLR is the Black Neutrik NC3. The wire is then covered in 1 layer of black Techflex braid. The black over blue jacket give it a dark blue color.
The cable is extremely smooth sounding with great low end and wonderful voicing. And will remove the veil all Sennheiser headphones just like the Silver Dragon. Most stock headphone cables are made of poor ultra thin conductors that work as a bottle neck for the sound.
If you listen to Rock, Alternative, Rap or Techno etc, then this is the cable for you
