In the Wedges and IEMs video, I talked about how in-ear-monitors can be custom molded to fit your ears. This can also be done for musicians' earplugs. You get an impression made by an audiologist, and I filmed my last visit to Musicians Hearing Solutions to show you the crazy pink stuff they put in your ear....

I got my custom earplugs from Sensaphonics and they work great! This is probably my 10th pair over the last 15 years- I wish they did a punchcard.
