Neat. I hope they work well for you. I don't know if you got the $90 or $150 kit. The $150 kit comes with more accessories, but the actual earphones are the same. One thing the more expensive kit comes with is a foam "Comply" tip. The foam tips are like foam earplugs. You squish the foam to fit them in the ear then the foam expands to seal the ear. The foam can offer a more secure fit and better isolation than the silicone tips. But the foam tips are more bother to take in and out. So maybe foam tips would be better for the live monitoring and you could switch to silicone tips for casual listening. Comply is a brand name. You can buy Comply tips that will fit the Phonak from a variety of sources like Amazon, HeadRoom, and others. Here's a tip on how to get in-ear headphones in your ears. It's a youtube video that shows the method. It's not in English, but the subtitles are in English. My 10 seconds of google-fu didn't find the English guide I was looking for. This video will do. With your right arm reach around the back of your head and grab the top of your left ear. Stretch the ear up to open and straighten the ear opening. Fit the earphone in. Release. That method will make it easier to fit the earphone in deeper and more consistently than just trying to shove the thing in. It will be interesting to find out how well they work for the live monitoring. I've never done live playing with monitors and a PA so I'm curious.
