I connected this up to my speaker on my treadmill. The vibration was a problem with my previous player, and this has proven to be very stable during operation of the treadmill. I am extremely happy with it's ease of use and vibration damping.
This is the best player for the price, when listening to long podcasts, it's easy to fast foreword or rewind quickly where most players take longer to do that. And as far as the screen to small, if your over 45 and you need glasses, deal with it.
