This is the Blue Dragon V3 Shure Pro headphone replacement cable for Shure SRH440, SRH750DJ, SRH840, and SRH940 Professional Headphones.
The Blue Dragon V3 Headphone Cable has been designed to match the Silver Dragon V3 Headphone cable but with a high purity copper conductor using the Ohno Continuous Casting Process. The Blue Dragon V3 Headphone Cable has the same geometry structure as the Silver Dragon V3 Headphone Cable only it uses UP-OCC Single Crystal Copper conductors.
The Blue Dragon V3 is a good fit if you do not want to add coloration but want to improve clarity and dynamics in your headphones. In addition, if you do not want to tip the headphone forward or back then the Blue Dragon is a wonderful choice and is also the "best bang for the buck cable" on the market today.
The Sennheiser HD600 has been one of the best phones for classical music because of the smoother warm sound. The HD600 is not as dark and laid back as the HD650 and so the neutrality of the Blue Dragon is the better fit for the HD600 signature. It is a great cable for a wide variety of music genres. If you are using a very warm tube amp and a forward headphone, the Blue Dragon is a good choice to keep the sound signature the same. The Blue Dragon V3 is also the most flexible of the full-size headphone cables and makes a good choice for headphones that use a single entry connection point like the AKG K702 and many of the Ultrasone headphones.
"I like the...Moon Audio Blue Dragon. There are numerous cable makers out there, many are good, but many more are just hobbyists with a soldering iron and a yen to be in business. With cables, the devil is in the details, I strongly suggest using cable makers with long years of experience and a good reputation.
If you have headphones with a hard-wired stock cable and would like to have them replaced, again, it is very important to find a reputable supplier who is very familiar and competent with this type of work. I'll happily recommend Moon Audio as one such supplier.", Tyll Herstens, Innerfidelity.com, February 26, 2013.
We also use the Blue Dragon V3 Headphone Cable 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, and Audio Technica headphones too.
The Blue Dragon Headphone cable we use the same 4 x 24AWG Teflon insulated stranded conductors using pure single crystallized UP-OCC pure copper with 7N purity 99.99998% as the main cable.
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 microphonics. It is a balanced cable geometry that can be terminated for either single-ended or balanced configuration.
Shure Pro Series headphones use a single-ended, single entry connector. While cables with balanced headphone connections may use balanced or single-ended amplifier connectors, this is not true of single-ended connections. Combining a balanced amplifier connector with a single-ended headphone connection can short the circuit and damage the amplifier. This is why the amplifier connections for this cable are limited to single-ended options.
