ER4SR Headphone 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.

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 I’m sitting still this isn’t an issue. Only when I’m active and turning my head a lot.

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.

Nice cables but still wish there was a greater selection of options for the etymotics. In terms of sound, noticable increase in brightness and separation of instruments on my er2se. Overall sound is much more forward. I would recommend these as an upgrade especially if you are using the er2se for studio use. Will see how break in affects the performance but overall I'm happy with them.

Works well, cables are pretty think and stiff though so you hear a lot of sound transmitted through movement of the cable against you or surroundings.

I don't know how anyone uses Etymotic without wrapping the cable around your ear to remove the cable noise. It's very uncomfortable and annoying to try and wrap this cable around my ear because it's so thick and doesn't like to bend into a shape. Also keeps twisting the earbuds out of place due to the weight and stiffness. The stock cable has no stiffness so it just flops around your ear however you wanted. Also can't tell which is right/left unless the light hits just right as the L/R letter is embossed in clear, the same as the housing.

kind of expensive, but very high quality and durable cable for my er3sr, functional without any detectable sound issues. It lasted 3 times longer than the original cable and is still going strong.

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.
