Concert ear plugs?? TDS3

Hi! Just wondering if buying ear plugs are worth it as someone who doesn’t go to concerts regularly?

I’ve heard that you can hear music better and block out screams and background noise, but I don’t really feel like buying $40 ear plugs is worth it on my end because I’m not an avid concert-goer (as of now at least).

Was wondering if anyone could share what they think from wearing or not wearing ear plugs.
