These cables use a pair of 2.5mm connectors that perfectly fits the following headphones:
Sennheiser HD700
The Sennheiser HD700 headphones are high end, fully balanced units, providing outstanding performance that can be improved when run with a balanced headphone amplifier and balanced cable. The stock cable can also be upgraded for better, fuller sound. We offer silver-Teflon upgraded standard and balanced cables.
Customer Steve tried these with his AudioQuest Nighthawks and said:
- I think the guys at Stereophile understated the impact of going to balanced mode with the Pono. It makes an obvious and completely positive difference, at least with the Nighthawks. This is especially true in the bottom end and in the overall low level resolution of the system. I thought the Nighthawks were wonderful with the Pono and the Audioquest cable. Well, they are even more wonderful with your wires in balanced mode.
- The construction is excellent, the length is good, and I think they will be sturdy enough for my planned use.
Note: The Stereophile article he mentions is available here.
Wire Selection.
You may choose a cable with Standard or OCC silver-plated copper wire with Teflon insulation. Standard wire is military/aerospace quality silver plated copper with Teflon insulation, 24 AWG twisted pair. The OCC cable uses a costly and premium wire formed of specially processed silver plated copper, with Teflon insulation and is of high purity, "5N" or better. It is approximately 28 AWG. This high purity wire sounds great and has been specially selected by us for its electrical and mechanical properties. Both types of wire are very flexible, can be bunched, and are durable.

Sleeving.
Our cables are fully sleeved with a soft, cloth-like black fabric covering.
These cables are available in various terminations- for the Pono Player balanced mode, standard XLR balanced, and standard 3.5mm and 1/4" TRS heaphone configurations (email us for TRRS options). The cables use our soft cloth-like sleeving for reduced microphonics. The connectors are terminated using Cardas silver solder.
PonoPlayer balanced mode termination (dual 3.5mm) to dual 2.5mm.
Our P-07 line of PonoPlayer cables provides a very high quality balanced mode output from the PonoPlayer to your headphones. These cables allow the highest possible quality connection for your high resolution Pono player files, balanced output to balanced headphones. 
XLR Balanced cables
Our S-07B line of cables provides a very high quality balanced connection from a balanced source to the headphones. We use industry standard Neutrik XLR connectors. The S-07B1 uses a single male 4 pin XLR while the S-07B2 uses a pair of 3-pin XLR connectors.
Onkyo/ A&K Cables
Our S-07-X1-AK line of cables provides a very high quality balanced connection from the 2.5mm balanced connectors found in the Onkyo DP-X1 and Astell and Kern players (as well as other 2.5mm balanced players such as the Cayin N5). These use a 4 pin straight 2.5mm male connector on the source end and a pair of HD700/ AudioQuest/ HE-1000 connectors on the other end.
