These two ukuleles are compared in the video.
We have a lot more detail on both ukes on the review pages - the Enya Nova U and the Lava U both with reviews and sound demos, but in the video below we compare the packages that these ukes are supplied with and how they face up neck to neck.
We think overall that the Lava wins, a more robust build, metal frets, better case (both ukes are supplied with cases) and a bigger sound.
A quick summary:
Enya Nova U - comes with rigid zipper case, USB charge cable, strap, capo and spare strings. Built-in controls and effects: volume, reverb and chorus.
Lava Music Lava U - supplied with hard case, USB charge cable, pick and cleaning cloth. Built-in controls and effects: volume, reverb, chorus and echo/delay.
