The 3rd gen Shuffle sounds great, better than both the 1st and 2nd gen IMHO (I have them all), however Apple really screwed up putting the controls on the headphone; its really not user friendly (Apple take note!). But all is not lost as Scosche have a couple of options with the tapstick and tapline accessories:
ScoscheDirect> Main Section > ...for your iPod > iPod shuffle
The voice over and addition of playlists on the new Shuffle is absolutely superb and you'll be blown away by how small the unit really is. You'll be pleasantly surprised with the sound once you've got some decent IEM's.
However if you can't be bothered using a 3rd party accessories to control the new Shuffle (which is a total pain in the arse) then
I'll champion getting a Sansa Clip, which really is a great player out of the box, just add a decent set of IEM's and your away.
Though Clip's slightly larger than the 2nd gen Shuffle as you'll see from the attached photo, it's still a small very fine device and well worth considering, the build quality is good for the money, maybe not a good as the Shuffle's if I'm being honest, but still well worth the money.
Wait 2 seconds and I'll be accused of being pedantic by mentioning that the Clip is larger than the 2nd gen Shuffle and huge compared to the 3rd gen Shuffle, plus build quality maybe not as good. The Clip has legendary status and a huge following here on Head-Fi - A reputation that's well deserved.
But I also believe that not enough people have listened to the 3rd gen Shuffle to make an informed opinion, if you can live with it's screwed up controls (i.e being on the headphone wire) then maybe it's worth a look - I suspect currently it's the smallest MP3 player on the market if size is important to you.
