iPod shuffle died on me as well after about 4-5 month of usage during exercising. Luckily I did not spend any money on it since I won as door-prize at local computer conference. Regardless I thought it should have been more sweat-proof.
Then I used
Series Walkman MP3 Player for a year or so and it worked good while it worked. By technical specs it was supposed to handle sweat and probably did however I abused it quite a bit by taking to hot-tub, sauna, pool at local Y. It's not waterproof so I did not try diving in the pool but I'd take on leisurely swims where I kept my head above the water.
Downside of this model - it was noisy in sense that if I used it at sauna then everyone at sauna could hear what I was listening to.
Now I have been using
E Series Walkman Video MP3 for about 4-5 month. So far so good but I am not sure if it is a good buy yet - it has to last more then 12 month at least, more then 24 month preferably, and more then 36 month ideally for me to call it a good buy. One of the main reasons I opted for this model was that it has FM radio option.
Downside of this model for me are control buttons and how easily is to turn it on without realizing that it's on and occasionally I have drained batteries overnight. Regarding control buttons there have been situations that instead of forwarding to next song I somehow managed to change playlist option to play just one song at the time requiring me to manually forward to next song after one finishes. I have learned to be more careful since and it has not happened in probably over 2 month now.
