Pros Same Clip+ audio chip (http://nwavguy.blogspot.com/2011/02/sansa-clip-measured.html)
Rockbox Super FW: http://www.rockbox.org/wiki/SansaClip (games)
Audio Format support: http://en.wikipedia.org/wiki/SanDisk_Sansa
Seemless support for 32GB microSD
Cons It can get stuck. Press the top bottom and hold for > 10s and the system will reset (audio files will not be deleted)
Summary Incredible bargain as a dedicated portable audio device.
Pros I LOVE all the features, the size, the ease of use. One of my favorite features that I can't find on similar products is the ability to record radio.
Cons We have gone through 4 of the Sansa MP3 players, each one died from a different problem. Some had quirks I learned to live with: locks up when adjusting volume in radio, headphone jack positional, but then they all become unusable!
Summary Construction is shoddy, won't last through the year. I'm switching to another brand even though it means I have to give up some features.
Pros Better sound than just about all the mp3 players out there
Super portable. Excellent for the weight room
Really good feature set
Cons Construction is sub par. Software freezes from time to time
Life span is questionable
Summary This the best option right now for people looking for an mp3 player for the gym or jogging. It is super light. The sound quality is excellent, better then any Apple products or any Android phone Ive listened to. The feature set is over the top. Radio, sd card slot, voice recorder. Really inexpensive especially for the features you get. Ok let me get to the down side.
The quality is not the best. I have owned 4 of these clips so far. In my experience only one of them lasted a little more then a year. The one that lasted the longest still works except for the fact the screen is dead lol. If you are looking for a feature rich great sounding mp3 player that is portable but has a life span of approximately 9 to 12 moths then this is your baby. I strongly recommend getting the warranty on this one, your most likely are going to need it. However for the price online for under 35.00 dollars I would buy it again. There isn't anything else out there that is ultra portable and sounds as good. Just make sure to back up your music or use and micro sd card.
Pros Great sound quality for the price
Cons Lack support of online services like Spotify or Deezer. It wasn't really an issue when the first Sansas came around, but it really starts to be one now, with changes in music consumption
Summary Great MP3 player for the price. It is just straight to the point: not really fancy but plays almost any music format and with GREAT quality. It basically sounds 3 times better than my iPhone 4.
One should obviously not compare it to high-end products given the price tag, but it still sounds better than the last iPods, iPhones, and any other smartphone and MP3 player below $200 I tried. You of course have to get rid of the ear-buds that comes with it though (just like any other MP3 player anyway). I just miss the support for services like Spotify...
Pros The best qualities are that it is small, lightweight, expandable via micro-SD card, fm radio, easy navigation, easy file manipulation, long battery life, multiple file types... everything I could want...
Cons doesn't connect to the apple-universe. NOT really a negative for me.
Summary If you haven't gotten an i-pod type mp3 player, and don't have any interest in contributing to Apple, this is the best MP3 player, by far. Ive had 3, and given 4 as gifts and I plan to give more of them for christmas this year.
