I personally feel like as you play with an amp and always practice with an amp you can hear ay more, i mean your hand should fully be in sync with your ears if your muting sounds shit fix that play differently you can kind of always automatically like hear for example if some strings are ringing and they shouldn't.
Also one thing i found is cause if you play fully by yourself you feel like you're the best but if you look at a video of you playing at a show or some other occasion you sound REALLY different so just record yourself once in a while!
