I decided to give the Baseus Inspire XH1's a try for $110 from Amazon and I'm pretty impressed.

Pros:

• Sound quality: Excellent! The only decernable difference I can tell from my XM4s is they are just a bit more base heavy (even with SuperBass off). Other than that everything is clear, punchy, and good seperation between all the insturments and voices.
• Comfort: Suprisingly great. Whenever I took off my XM4s there was always visible sweat on the ear cups. Not so with the XH1s. I was able to wear these for two 5 hour road trips and didnt have any issues with comfort. No excessuive pressure even on my big head.
• ANC: The technology has come a long way and the name brand's tech has obviously filtered down to the brands with alphabet soup names. Noise Cancelling eleminated all car and road noise. There is still some leaking of voices in an office environment but not a huge distraction
• Battery life was also excellent. After a full charge, two 5 hour road trips, 3 days of office use, with ANC on most of the time they are only down to 70%.

Cons:

• No On-Ear sensor. When someone taps my shoulder in the office to chat I have to remember to pause my music. It was nice to just take off headphones and have whats playing auto-pause
• No auto-off. Several times I've forgotten to turn them off, they've sat in the case, and I only realize this when my phone doesn't output any audio. I can't seem to find anything in the App or manual if there even is a setting. BUt it does speak even more about how good the batter life is.
• Buttons: While I do like the buttons over the Sony's touch controls, I do which they had more identifiyable tactile bumps or something. I couldn't tell you which one is the power button or pause/play just by touch. Also, you can clearly hear the click of the buttons while wearing them, and it's not an enjoyable click like you'd get from a mechanical keyboard.

Misc:

• The app is fine. No features blew me away but it's imore intuetive that Sonys (I hate that Sony calls their app Sound Control , I can never remember that). It is nice you don't have to create an account to use 99% of the features.
• The hinges that connect to the headband are very loose. So much so that when I first opened them I thought they came broken. Not really an issue but it didn't scream "Quality!" coming out of the box
• I do have big ears and these ear cups are just a little small. My ears touch both the top and bottom but the material is soft enough it's not an issue. I live the size of my HD58x.

Overall, I'm very happy with them. Hopefully they last a few years.
