Yes. 40 seconds of shock protection is the same as most CD players.
I tried a MD player (not player/recorder) that had 40 second
skip and ran into skipping when I used it with my water pack.
One thing I did notice with my MD devices is that alignment matters.
For instance, the Sharp MS-702MK has a slot-load mechanism (instead of a clamshell mechanism that is prevalent today). It makes it slightly bigger but it's easier to change MDs.
I found that when running, I had to have the orientation of the slot to be either up or down. If I held it so the slot was on the side (oriented right or left), it would skip if I had it in a pack or if I had it my hand. Orient it so the slot is up and it didn't skip. I found the same to be true with the Sony player I tried.
I would check out
Minidisc.org for more information on players and recorders. Lots of great info there. Right now, I'd recommend the Sony MZR70. It's got 40 seconds of shock protection, can run on a rechargeable or regular AA, and is about the size of 2 minidiscs (although it bulges on one side with the AA battery).
You can also do what I'm planning on doing with the Nomad II MG: cut a couple of holes in the case and loop velcro through it. Then you can velcro it to your arm. Some folks have reported having luck preventing skipping with this since it's not bouncing as much as when it's attached to your back.
As far as best MP3 player, I'm not sure.
If your requirements are just storage, the Rio 500 has gotten great reviews.
If you want FM radio reception, I like the Nomad II (but it's limited to 64 MB since it has no built in memory) or the Nomad II MG. The Sensory Science Rave MP2200 has gotten some good reviews as well.
Since this is a hot deals site
😀 you can get the Nomad II for about $200 by doing this:
Go to
Office Express where they have it for $233. Then go to Staples and look for the
Nomad on their site where they have it for $279. Price match and use one of the many $40 off coupons and you can get it for about $193 + $8 for shipping. Not a bad deal.
