I have no idea, you should ask before buying to make sure.
this is a pic of the bass edition http://i90.photobucket.com/albums/k240/ofey_s/VSONIC/GR02B-03.jpg
I honestly never seen something so complicated to buy. Even lendmeyourears on their site have 2 versions with the same description but only one marked as "bass edition"
it looks exactly the same as mine except for the 3.5mm plug which is right angle and squarish with the white background and logo embedded a bit inside at the back of the plug. :D and it is a bass edition
