I don’t know about you but when I am working out I have a lot of trouble keeping my earphones in place. As I sweat and bounce around, my earphones fall out of my ear. This is definitely not good on a treadmill. Especially if you are on a serious incline. I also have trouble hearing my audiobooks when the gym is crowded and the club radio is blasting. if you use your iPod or mp3/music player a lot, it's worth the investment to replace those horrible headphones with something a little more upscale.

With these issues facing me, I decided to look into some good earphones. What I learned was quite educational. I had a chance to learn about cancellation and isolation technology. I learned about the technology and two of the best isolation earphone manufacturers: Shure and Etymotic Research. The paragraphs that follow communicate what I learned.

Pro-level sound isolating earphones were developed as to allow musicians to hear their own music in loud onstage environments. Sound isolating earphones work by using soft, supple sleeves to block background noise, allowing small speakers to deliver precise sound directly to the ear.

Sound isolation allows you to hear greater detail at a lower level than is possible with most headphones or earphones intended for portable use. The isolation earphones I reviewed have one more redeeming factor: they are great for exercise and workouts. The isolation earphones usually sport both foam and silicone covers to secure the earphones in your ear.
