All Krieg Heads in the Vita version?

So, the vita version does show a total of 18 Krieg heads and I was thinking the last one is the Goliath head from the Diamond Plate Loot Chest Edition or the Community Day head but I saw recently the My Ears Are Ringing head which is basically from Tiny Tina DLC and should not be in the vita version.
The wiki says My Ears Are Ringing is also a very rare drop from Henry and Badass enemies.
I did probably 300 Henry’s in the last 2 days … waste of time?
