Super alternative to original cable.
My first etymotic cable died in a week, and you know what they cost. This has already lasted 3 weeks of giggling and I feel like it is beefy and durable. Works great also. It is a little heavy, but I just use a clip to support it.

Good but STIFF
Works well and quality is there. For me however, the cable is too stiff. This causes the earphones to wiggle out of my ears compared to a more supple cable. If Iโm sitting still this isnโt an issue. Only when Iโm active and turning my head a lot.

Destroyed one of my ER2XRs
The keyed MMCX connector on the cable I received was much too tight for my ER2XRs. The connector barrel actually snapped off inside one of the IEMs when I attempted to insert it. I was unable to extricate the broken metal barrel which meant the IEM was completely ruined. Luckily I had an old backup pair of drivers, but an aftermarket cable doing this kind of irreparable damage to $150 IEMs is just awful, and a sign of poor quality control. okcsc may want to investigate the connector tolerances across the Ety lineup before advertising compatibility with the ER2XR. Oddly, the cheaper braided okcsc HBC13 Earphone Cable doesn't have this issue and mated nicely with my ER2XRs. I strongly recommend getting that one, instead of this clear 4-core cable.

Not good
UPDATE: The cable only lasted about 6 months. It became stiff and then the connection began dropping out. The insulation started coming off near the metal bits because of bending. I ordered a new one because there isn't any other choices really. Worked ok for a while. With heavy use, the cable became stiff and impractical to wear. I'm trying dipping it in boiling water to make it like new. Seems to help a little bit. The connectors are more reliable than the factory cable, and hold the earphones very well, but sometimes they need to be taken out and blown into + reinserted.

Good quality but stiff
Much Stiffer around the ears than the original etymotic but seems strong and looks good
