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: High quality cable - Works great with my Etymotic ER4XR. After going through two OEM cables from Etymotic, I wanted something more durable, so I'm glad this cable exists. This cable feels heavier than the OEM cable, which can be uncomfortable if the full weight of the cable is tugging at my ear canal. However, this is easily remedied by wearing the cable over my ear, instead of wearing it straight down. Over-ear wear also has the benefit of reducing microphonics. The cable length is shorter than OEM, but I actually prefer this length.
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.

### ⭐⭐⭐⭐⭐ High quality cable
*by A***R on May 2, 2025*

Works great with my Etymotic ER4XR. After going through two OEM cables from Etymotic, I wanted something more durable, so I'm glad this cable exists. This cable feels heavier than the OEM cable, which can be uncomfortable if the full weight of the cable is tugging at my ear canal. However, this is easily remedied by wearing the cable over my ear, instead of wearing it straight down. Over-ear wear also has the benefit of reducing microphonics. The cable length is shorter than OEM, but I actually prefer this length.

### ⭐⭐⭐⭐ 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.
