content: Super fast delivery. The last ear loop on my Jawbone had worn out. The large ear gel fit over the Jawbone earbud and, with a little superglue, stays there. It fits in my ear without using any loops. After a full day, the ear is a little tender, but it is getting better the more I use it. I would highly recommend the ear gels for anyone with a Jawbone. Improves sound and the fit of the sensor with the jaw.
