Input:
The Plug earphones are the best. I have been using them for 10 years. They are comfortable and allow me to hear my audio-books without turning the volume up to high because the earphones cut out background noise like ear plugs (thus "The Plug"). The sound quality is good. These usually last me 9 to 12 months so I feel like $13 bucks is a fair price.
