I purchased these headphones for my wife having owned the Sport version for many years. I expected that they would give her the same satisfaction that mine had given me.

After a while, I noticed that she wasn't using them for taking her walks. When my Sport model broke down after many years of use, I tried using hers.

First I tried programming them. After rereading the instructions a few times, I finally figured out how to do that. It was not intuitive, and I couldn't do it again without the instructions.

Then I went for a run with them on. I was very disappointed in the sound quality. Without the megabase on they sounded very tinny. With the megabase active, they sounded like what I thought was normal, not enhanced. In addition, I never got the feeling that I was getting stereo sound out of these headphones. In fact I'm not sure they are stereo - I couldn't find anything on the box or headphones that says they are.

Like my wife, I ended up not using them either, having decided it was better to run without them than to put up with poor sound quality.
