>> I have the Sony MZ-R55, and the advertised 40 second shock protection DOES NOT live up to its reputation. I ran into the same problem, and this is the solution that I came up with: I strapped the unit to my upper arm with a sweatband. You'll find that the MD player will be held snugly to your arm, and the motion of your arm is a lot more gentle that then swinging of your hips. This should also be fine for just about any activity you want to try. I have the same Sony MZ-R55 and its works just fine. May not be the most stylish solution (but after a fanny pack, it's not that bad); get a retro sweatband and it'll look damn good. _______ In my other life, I run the electronics section on Epinions.com (some dubious-sounding guy named "John Jones" mentioned it in a post the other day). Anyway, I'd like to invite everyone to come post reviews of their units on the site -- the masses out there need to know about MDs (both the good ones and the bad ones!). Also, you'll get paid every time someone reads your review. We're the experts on MDs; let's let others know about them.
