This might just be me, since all ears are different, but I have never found ear plugs that work for me. Everyone in a band always talks about the importance of protecting your hearing, but at what cost? Every time I play with ear plugs on, I can barely hear the band, and less so, the bass sound. If this is quite normal, then how are you supposed to "listen well to the band" if you can barely hear yourself and your band mates? I've been through 3 different brands of ear plugs and every pair makes me a worse player and I more frequently have worse time/feel and cant sing quite as well.
