Wow. 4 years and no reply?
I'm also trying to find out more about the Obsidian V3. I have 27 sabers and no OV3. Is there any benefit to the V3 over the V4?
The v3 is $10 less expensive.
What is the difference between V3 and Lite?
Short version:
Obsidian LITE - Cannot change sound fonts, cannot change volume. Comes in one Volume only, and it is LOUD. Runs on 4 AAA batteries. Cannot have recharge port.
Obsidian v3 - Can change sound font via Obsidian Launcher, only one sound bank available. Can change volume via Obsidian Launcher. Runs on 2 14500 Li-Ion rechargeable batteries. Can have Recharge Port.
Obsidian v4 - Can change sound fonts via power switch on saber, can cycle through 7 (I think) different sound font banks. Can change sound fonts in sound font banks via Obsidian Launcher. Can change master volume via Obsidian Launcher. Comes with silent "Mute" font as one of the initial default fonts. Runs on 2 14500 Li-Ion rechargeable batteries. Can have Recharge Port.
