NoNoise Ear Plugs
I'd had a similar set of ear plugs that I used for shooting that I really didn't care for. I thought they were uncomfortable and they didn't lower the sound level that much.
When I first got the NoNoise plugs, I liked them. They seemed to work pretty good and were fairly comfortable. They seemed to perform as advertised and I was able to hear my SENA SMH-10 just fine.
However...They had a very different personality when used for a long period of time.
The first day they were okay. The second day, they started to get a little painful. The third day, they hurt so much I had to abandon using them.
I'm also reasonably certain that I ruptured my ear drum. This may or may not have been as a result of these plugs. When I removed them after the third day, it was very painful, there was blood on the plug, and I had a lot of ringing my ear. Upon returning home, my doctor speculated that I had ruptured my ear drum as it was very thing. By the time I had the appointment (one week later) it had healed.
I my eardrum had, in fact, ruptured, it was probably because I was going over some very high passes and the seal in the ear canal is very tight.
I didn't use them the remainder of the rally and will not be using them again.
