In this instructable, I'll document how I modified a pair of Harbor Freight item # 94334
hearing protection ear muffs to get the sound blocking benefits of the hearing protection, plus be able to listen to music or a scanner. I have tried using ear buds under the muffs, but they hurt my ears after a while and were always getting knocked out. Now I can listen to music at the same volume level I normally would, even while cutting the grass without hurting my ears. The Harbor Freight muffs are comfortable enough to wear for hours of use.
