## Customer Reviews

### ⭐⭐⭐⭐⭐ 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 be careful about size
*by P***Y on April 16, 2025*

I just began using it, and it seems well-made. But there are a variety of versions by this maker with different plug sizes and shapes, so it's not obvious which one will fit your Etymotic in-ear earphones, and even the right size ones are a little difficult to get to fasten to the earphones.

### ⭐⭐ Not good
*by C***  on April 8, 2025*

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.
