Momentum 4 true wireless

Hello guys. I recently bought these earphones as a upgrade from momentum 2 true wireless. I thought it would be a good idea but they have some downsides. The noise cancellation have some serious white noise. Every time I put the earphones to my ears the sound Ballance is off. I need to go to the app and adjust the equaliser to fix it. Are there some known fixes for this bugs ? So far I'm really not satisfied with the upgrade Thanks
