I used WAVS in-ears. They were 3D printed from 3 scans of each ear to fit my ears perfectly. You can order them with any of 3 driver configurations. They are the best this I ever had, FAR better than generic earbuds. When I had them in I could FEEL the band around me but not hear anything I told the monitor mixer to exclude. And I am not exaggerating. I had to watch the drummer count the songs in because I couldn't hear his sticks clicking. If everybody used in-ears you'd never hear feedback again. We opened for a band once who used no stage amps and no monitors. I stood side stage when they started and all you could hear was drums. When you walked out into the crowd you heard the music. Had they used electronic drums all you would hear is sticks hitting pads. I loved it!
