I am currently using Sennheiser’s ocx 686g but they’re just staring to lose connection to the port when the cable gets pushed around, so I was looking to see if there’s anything better than just replacing these every 3-5 years at a ~100$ price point wired preferred but not a hard deal breaker or anything
The 4’s have spatial audio and heart rate sensors. The NC don’t. There may be other differences too, but I don’t have either one. I do have the linkbuds s though, and I like those a lot.
