We have covered a lot of Klipsch products before, such as the Klipsch Image S3 Noise-Isolating Earphones and the Klipsch AudioRock Outdoor Speaker.
Klipsch has just created the S5i Earphones, and they may be the most durable in the market today. They can withstand extreme conditions such as cold temperatures.
It also allows the user to listen to music and make calls on the iPhone. They come with a carrying case that can double as a flashlight.
You should be able to get these headphones at the Klipsch website for about $191.
