Shure E2 Earphones
In case you're worried about getting your iPod stolen thanks to the tell-tale white earbuds, or (like me) you just can't stand the way said earbuds feel, the Shure E2 earphones may be a good replacement set.
The first difference from the defacto iPod buds is that fact that the E2 series fits inside your external ear canal, and not precariously nestled up to the Crest of Helix (that meaty part in front of the canal - okay, here's a diagram). The benefits are two-fold.
1 - The earphones do not fall out as easily.
2 - The sound is directed right into your ear, providing better sound quality and eliminating surrounding noise.
As a frequent jogger, I was most concerned about keeping the earphones in place. The set comes with several different sleeves to provide comfort and stability. The disposable foam pads were the right match for me. Even so, it took weeks for the pads to properly "shape" into my ear and provide the best sound and fit. The reusable "flex sleeves" were too rigid to stay in the canal. While working out, the flex sleeves became slippery and would rotate outward, giving a weak signal and almost no bass.
The fit of the earphones requires the cable to go down the neck and back, as opposed to the front of your body. This took some getting used to; but is not a distraction with frequent use. The cable is short, so you'll need to pocket the iPod, or use an arm strap. The cable is not long enough to stretch to the display panel on an elliptical machine, for example. Again, a minor disurbance; but not a deal breaker.
Judged simply by quality and price, the Shure E2 series is a safe bet. Far better than the iPod earbuds, and far less conspicuous. Give them time to find the proper fit and you'll be a happy customer.
