## Description

desertcart.com: okcsc ER4SR to 3.5MM Upgraded Replacement Cable for Etymotic Earphones Cable 4 Core for Etymotic ER4SR ER4XR ER3XR ER3SE ER2XR ER2SE LN008099 3.94FT : Electronics

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

## Customer Reviews

### ⭐⭐⭐⭐⭐ Super alternative to original cable.
*by K***N on January 4, 2026*

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
*by A***R on April 2, 2025*

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.

### ⭐ Destroyed one of my ER2XRs
*by M***E on January 7, 2026*

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.
