These cables use a pair of 2.5mm connectors that perfectly fits the following headphones:

Sennheiser HD700

AudioQuest Nighthawk

HiFiMan HE-1000

These 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 Standard or Heavy silver-plated-copper wire with Teflon insulation.  The 20 AWG (Heavy) wire is massive compared to most headphone wire.  This wire provides superior conductivity but is more rigid (less flexible) than most headphone wires.  The wire can be bent easily but tends to hold its shape when bent.  It is suitable for home listening but not for travel or active lifestyle purposes (such as working out).  For a more flexible everyday wire, our Standard option is 24 AWG  silver-plated-copper wire with Teflon insulation.  This wire is still thicker in gauge than most hair-thin headphone wires, and uses optimal Teflon insulation for reduced capacitance.  However the standard wire is very flexible, lighter and with a looser weave.   It will not hold its shape and is suitable for working out or other active uses.  It sacrifices a small amount of performance for physical utility.  For balanced applications, such as Pono Player Balanced mode cables, we recommend the standard wire as the sound quality of the Heavy wire is only marginally better than the Standard wire.

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. 

The "heavy" P-07 cables have two sections of twisted, insulated wires.

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.
