Build Quality.

7N Neotech UP-OCC Copper Cryo Litz

This is one of their most popular cables. The one I have is made up of 4 cores of Neotech’s 7N UP-OCC Litz 1 structure wire (wire’s link in EAC Store). The quality of wire is very good, it being flexible and supple. The braid is tighter pre-Y-split and a bit looser post. I chose to have ear guides and they are ergonomically shaped and comfortable. Microphonics are very minor and do not interfere when music is playing.

I chose Eagle’s large Rhodium-plated jack in 3.5mm. This jack itself costs $14 alone and is one of my favorites out of all the cables I have as it oozes high quality. It is very solidly built and feels great to hold and use. Rhodium plating also lasts longer than gold plating. As for connectors, I chose classic silver style 2-pin versions. They cost around $8 for a pair and like the jack are high quality and inspire confidence when plugging them into tight sockets. I chose the small black carbon fiber Y-split for this cable and that too is of very good quality and looks pretty cool too. The chin slider sadly is a bit loose and doesn’t work as efficiently but fits in the design language well.

It is cryogenically treated and strengthened but American Cryo-parts. I do not know if that makes a difference or not, but well at this price, what’s the harm!

7N Single Crystal Copper Cryo Litz Special Tuning Edition (STE)

This one is a bit more expensive than the previous UP-OCC cable at $135 . It feels slightly thicker and has a PE sheath which makes it a bit more solid than the UP-OCC cable, in a good premium way. The PE sheath also makes the braid feel better and tighter post the Y-split. It is also more flexible and easier to wrap than the previous cable. This too has the same comfortable ear guides and very minor microphonics. Overall, I like this one’s feel better than the UP-OCC.

Like the UP-OCC cable, I again chose Eagle’s large Rhodium-plated jack in 3.5mm and classic silver style 2-pin connectors with this one too. For the Y-split I went with the Red Sandalwood type instead for a change. It is bigger and fatter than the one on the previous cable and I much prefer this one. The chin slider works better on this cable than the previous one.

This one too is cryogenically treated and strengthened by American Cryo-parts. I do not know if that makes a difference or not, but well at this price, what’s the harm!

Technical Measurements.

7N Neotech UP-OCC Copper Cryo Litz

Resistance – 240 mΩ average
Capacitance – Around 72pf average
26 AWG
Type 1 Litz

Though the resistance measured slightly higher than I was expecting (I expected around 180mΩ), it actually conducts cleaner in practical usage, providing a slight volume boost over most stock cables.

7N Single Crystal Copper Cryo Litz STE

Resistance – 150 mΩ average
Capacitance – Around 68pf average
26 AWG
Type 1 Litz

I’m writing average values on the safeside as my main hi-res multimeter is down and the standby one is not as sophisticated as the main one. So, I borrowed another hi-res multimeter from my engineer friend to cross check quickly.
