I still enjoy them for music. But the battery life alone for calls is weak — I only get about 1 hour of talk time.
You don't want to walk around the town with earphones that isolate too much. My coworker was hit by a car as he was jogging while wearing IEMs. He couldn't hear the car horn and he was hit by a driver who couldn't stop his car in time. He didn't suffer any major injuries but he learned his lesson and now only jogs with open earphones.
I’m talking about external background noise that the mic picks up.
In both cases I have received no complaints, and have even inquired about how the noise is recently. People can't hear my obnoxiously loud road noise at all, it gets canceled out.
Active noise cancellation is not the same thing either. See https://krisp.ai/ for what you really need, and this is not something best done at the physical device level.
When I got hired for my current job I did both interviews from the parking lot of a local Starbucks for exactly this reason.
