Don't pay a bunch of money for replacement tips, instead convert your TV Ears to work with ear buds.
When my TV Ears plastic ear hangers broke I decided it was time to do something about it. I had been resisting buying new foam ear tip replacements and I tried different foam things but it only worked so so. Finally when it broke I took it apart and soldered on a standard 3.5 mm stereo jack and it works great with regular Apple earbuds.
I got tired of having to charge it so I got a sterio extension cord and I use the charger base on the armrest next to where I sit.
Nice, simple fix. Thanks for sharing this!
