IE 600 Upgrade cable

This is by far the best upgrade cable for the IE600, the fit, size and sound quality are perfect.

Absolutte Must have for IE600

I was on the fence of returning the IE600 due to its absolutely lackluster performance from the headphone cable. No product should be that faulty. My friend convinced me to give them another go but to buy a null audio cable. Not only is the connection now solid and dependable, but the sound signature is everything I was expecting when I bought them in the first place. Cable construction is better than anything I have purchased, they are comfortable, high quality, and really fantastic across the board. Any more high end IEMs I buy, the first place I'm next is to build a cable through this website. 100% worth it!
