Apparently you're suppose to wear them to protect your hearing, but do you? That ringing you hear the next day is thanks to the damage your ears have experienced from the loud noise.

I don't.

After this weekend I'm starting to think it might be a good idea.

No and I never have ringing in my ears

Yes. It blocks out the AWFUL bass and filters through the vocals so you can still hear every note

I don't and I got to concerts every month. Have yet to have a problem.

No, I don't.

live life to the fullest, worry about about your ears when you're an elder

No I happily let Katy **** my ears out last night

Yep! I'm a music producer, I need to!

I thought about it after I went to a concert and the ringing didn't go away for a few weeks but then never acted on it.

I don't and I've never experienced ringing in my ears??

No!

I've got slight tinnitus because I never used to do it but I don't want it to get worse so now I do

Did she have a live TV performance last night that I wasn't aware about?

Nope but sounds like a good idea. Will do next time! It's not like it sounds good having bass literally rattling through you. Lemme find some that aren't that garish orange.

I do, after being assaulted by the speakers front row at a metal festival.

Governments try to limit concerts at 100 dB by law. Still loud enough to get hearing loss, but not loud enough to really make you feel pain.
It depends on how loud it is and whether I can still hear the vocals/music good enough through it. I took my earplugs out for Katy and Tarja Turunen. It is not necessary with my current ear plugs, it has a low absorption filter too.
Not the construction workers ones for blocking off the noise of power tools.

There are ear plugs for music and changeable filters to adjust it to the loudness of the concert.

No
