Review: Amazing Cable! - This cable drastically improved my BASN IEM’s. These IEM are great but they sound even better. My mix is balanced and sharp. It was easy to attach, and the build quality of the cable is very impressive. The look took me back to my childhood of playing with lanyards!
Review: Budget friendly option for IEMs that require and MMCX male connector - Works well with my expensive-ish IEMs which needed to have their stock cord replaced when the connector unexpectedly broke during a gig. Worked so well, I purchased a second cord as a backup.
