After making a few Telephone Handset Microphones I came to realize that all of these handsets had perfectly good speakers that were not being put to good use.

I set out to correct this problem.

This is the natural solution.

Sockphones are socks that are headphones. The sound quality isn’t the best, but they are very comfortable. Sockphones can be made with all variations of socks and can also be made of every material, in every assortment of colors and in all sizes. They can use any form of two-speaker headphone solution.

The combinations are out of this world!
