text: Worked well for a few months. Sound quality is okay. At first there were no problems, but over the last few weeks (headphones are only three months old) they lose the signal if they are more than two feet from my cell phone. For example, the signal is generally okay while running on an elliptical machine if I rest my cell phone on the elliptical's display panel. However, if I put the phone in my gym short's pocket (and remain standing still) the headphone's will lose connection.
