The original Yurbuds are built to slip over most ordinary earbuds, like the ones that come with MP3 audio players and some smartphones. They sell for $29.99 at yurbuds.com. To make sure they fit correctly, customers are asked to upload a photo of their ear along with their order. The company uses the image to calculate which tips would best fit your ears.
With the tips locked into place, the headphones deliver high quality sound while keeping out perspiration and letting in enough ambient noise to stay safe.
The Yurbuds Inspire series includes tips, earbuds, and cable controls. Prices range from $39.99 to $59.99 at the Yurbuds website, at specialty athletic stores, and at national chains such as Best Buy and Dick's Sporting Goods.
If the new Yurbuds don't fit as well as you think they should, owners can return them with a photo of their ear to get a different sized replacement.
