MX2 was great, broke mine. Just recently realized how much better mx3 is to mx4. MX4 dropped aptx support and the mics refuse to work with macOS, mx3 hums(less) along working great (aside from the bent wired jack from more stumbling)

Push it to ~$40 and get a decent portable induction. Anything is better than burning fuel in your face, but induction can burn a lot less cooking grease and food too. Proper venting is still important and some level of recirculated air filter goes a long way. Every step helps. Ouch, my lungs!
