Review on Linsoul High-Fidelity ISS014 with Detachable Beryllium Diaphragm by Elizabeth Brooks

Great sound, poor MMCX connection quality. I switched the cable to another MMCX cable I had laying around and didn't have any cutouts unless I physically twisted the connector, which is better than a standard cable. At least now you can listen to it. This problem is common on this model, not recommended. Update: Rating changed to four stars, another cable solved the problem.
