| pin # | Use | Color | Pin Numbers reference a BP-325 Stereo Headset Connector. The headset is left/right reversable, therefore the "left" and "right" designations are somewhat academic. The earpiece on the side with the feeder cable uses the red wire for ear high. |

| pin # | Use | Color | The Ear-piece wires being identified as High or Low, is only important for consistancy between the two ear-pieces of the same headset. While you would never want the left earpice to be out-of-phase with the right, having both of them opposite from another headset will not cause a problem. The basic Sennheiser supplied documentation does not include a wire function chart. Other Sennheiser documentation does include conductor/wire code for the three available cables. The High-low designation indicated here is a convention taken from the earlier, HMD-24 model. |
