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. ## Frequently Bought Together - okcsc ER4SR to 4.4MM Upgraded Replacement Cable for Etymotic Earphones Cable 4 Core for Etymotic ER4SR ER4XR ER3XR ER3SE ER2XR ER2SE LN008099 3.94FT - Etymotic ER2XR Extended Response Earphone, Multicolored - Qudelix-5K Bluetooth USB DAC AMP with LDAC, aptX Adaptive, aptX HD, AAC (Dual ES9219 3.5mm Unbalanced & 2.5mm Balanced Output) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/581394351-okcsc-er4sr-to-4-4mm-upgraded-replacement-cable-for-etymotic](https://www.desertcart.pt/products/581394351-okcsc-er4sr-to-4-4mm-upgraded-replacement-cable-for-etymotic) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-22*
