There are several audio players out there capable of playing Ogg Vorbis. One of these which works perfectly together with Linux is the Meizu M3.
Originally I had an iAudio U2 player – that device was close to perfect: long battery life time, 2 GB storage, small, beautiful, capable of playing MP3 and Ogg Vorbis, and so on. Unfortunately, that one was stolen quite some time ago (the first thing ever stolen from me ).
Later my girlfriend wanted to have a MP3 player and settled for the Samsung YP-T9JQB (which has of course Ogg Vorbis support). With a new firmware this one also worked pretty well with Linux. The only shortcoming is that you have to invoke a rescan of the music database manually after unplugging the device and that it is detected as two drives by Linux.
Now it was time to get myself a new player – and I chose the Meizu M3 – called “Music Card” – in white with 8 GB. Besides the obvious Ogg Vorbis support it also has the ability to switch between USB Mass Storage and MTP. This makes it possible to use the player just as you like with all kinds of operating systems (especially with older Linux, Windows 2k or Windows XP without the newest Windows Media Player) since these do only support USB Mass Storage. Luckily it also rescans the music database automatically after unplugging. Also it is sold at reasonable prices. I would only have wished that the battery life was as unbelievable as with the U2, but for a price around 100 Euros you can’t expect everything.
So if you look for a shiny new audio player and don’t want to buy iAudio, Meizu is another good option.
