Notes on the Balanced Cable Connection Mod (cable end termination, not at ear cup entry):

This mod was performed by me using high-quality silver solder and utilizing the original high-quality Sommer-Cable SC-Peacock Mk II headphone cable. This is an extremely high-quality cable that is used by the absolute best recording & mastering studios in Europe. There is absolutely No Reason to use any other cable.

I have been soldering and building custom audio and radio electronics since I was 12 years old...and I am old & gray now. :p This mod was done at a professional level.

This Balanced Cable Mod was done in order to take advantage of the Balanced Headphone Output of my OPPO HA-1 headphone DAC/Amp, which these T1 headphones sound absolutely incredible on! :) No other mods were performed.

The original 10ft (3m) headphone cable was cut approximately 6" (15cm) from the end of the original Neutrik gold 1/4" TRS connector.

Then a high-quality 4-pin male Neutrik Gold #NC4FXX-B connector was silver soldered to the cut end of the remaining 9'-6" straight headphone cable.

To create a high-quality adapter back to the original single-ended 1/4" Neutrik TRS plug, a matching female 4-pin Neutrik Gold XLR connector was silver soldered to the remaining ~6" pigtail that had the OEM 1/4" TRS Neutrik Gold plug left intact on the OEM cable. (See photos).

With this mod, these headphones can be used with either a Balanced (differential) 4-pin XLR headphone amplifier output, or the original 1/4" TRS single-ended plug. A standard 1/4" TRS to 3.5mm TRS single-ended adapter (not supplied) can be used for 3.5mm (1/8") TRS devices.

Only Neutrik's highest quality #NC4MXX-B & #NC4FXX-B 4-Pin XLR Connectors were used for this mod (Black XLR Shell with Gold contacts) to match the existing Neutrik gold-plated 1/4" (6.35mm) TRS plug.

When the Balanced XLR connection is used, the overall cable length is less than 6" shorter than the 10ft OEM straight cable. When the XLR-to-1/4" TRS adapter is used, the overall Length of the cable is within 1.5" of the original.


I also have a set of GRADO SR125 open-back, on-ear headphones with Yellow Sennheiser pads plus a spare set of Original Grado pads for sale in EXCELLENT Condition. Please inquire if interested.
