Great Cable for IE 600

Great sounding and looking cable for the Sennheiser IE 600. Had some issues with my original order, but great customer service handled it perfectly. Very happy with the cable. More secure than the original stock cable, with less microphonics and memory. Very happy with my purchase at Null.

High Quality Upgrade Cable [IE600, 2.5mm termination]

I ordered the 2.5mm jack and these fit pretty good with my IE600s. Only slight issue, is that with the way the IE600s are designed, its a bit too easy to disconnect the MMCX connector from the cable when I reach to take them off from my ears.

Other than that the cable is nice and light, and seems to be built really well. Really happy with it, even if there's a slight issue with the MMCX connector, but that's more of a IE600 design issue I'm sure.

Incredible cable

Bought an upgrade for the uncomfortable IE600 stock cable and I couldn't be happier. Extremely comfortable and is made from high quality materials. They really make the IE600s sound incredible
