I slide a pair of cheap earbuds under my hearing protection while I mow and listen to podcasts and music on my phone. The audio is acceptable for podcasts but it's lousy for music. I recently upgraded my Spotify account, and one of the perks of their premium service is 320 kbps streaming audio. Spotify's free accounts are only permitted streaming quality up to 160 kbps. The difference is significant and even more so with a high-end pair of headphones.
I wanted to take this listening experience with me using the Spotify app on my phone while I mowed my lawn, but the high-end headphones offered little in the way of hearing protection. So, my solution was to mod a pair of 3M hearing protection earmuffs.
I decided to take the speakers out of my high-end headphones and put them in the earmuffs. The pictures that follow show you how I did that. Please consider this, less of a step-by-step Instructable, and more of a proof of concept. This is something you can do with any pair of headphones. Enjoy!
Step 1: I Dissembled the Headphones.
Step 2: I Glued the Contacts Down on the Speaker to Prevent the Thin Wires From Breaking Off the Solder Joint.
The headphone cable plugs into the headphones either on the right or the left. The black, plastic piece on the right of the photo is the jack. Both speakers have these.
