I'm not sure the earbud types offer equal protection compared to those that enclosed the ears.

I hate shooting indoor for this very reason.

For most indoor range if people are shooting pistols, I think any electronic over the ear should be fine.

Once someone starts shooting long guns or pull out a .44, then you'd probably want to throw in a disposable inside the over the ear.

I have found the Peltor 500 to be very good in most indoor situation without having to add an additional ear plug.

Whichever model you decide, you MUST replace it with GEL CUPS. It's a game changer.

PSA has plenty of options for over or in the ear including several Axil options some branded like SIG.

Get on the mailing list and you'll get plenty of emails with them listed some times at 50% off.

Right now several Axil and others are on sale.

Thanks for the link. I ordered the JTS M20BT ( an upgraded version of the Earmor I presume).
They seems to fit fine but I was concerned about replacement tip and the ones I got on Amazon fit perfect (same post diameter in Med) in case anyone else was looking. There are also the same tips in S,L I assume.
