I thought the sound of the Vance/HL headset was pretty good but the fit was terrible until I took matters into my own hands and modified them. I replaced the headband with the headband from a set of Harbor Freight $7 hearing protectors which were the same style and then super glued the pads from those same protectors onto the HL ear pads to make them deep enough to not smash the ears down. I would have returned the Vance muffs soon after I got them because of the fit but broke the original headband piece trying to bend them into a comfortable enough size to be wearable.
I have not used the GG headphones specific to the Deus but have used GG Ultimates and the adapter clip and the sound is a bit more bass than the Vance/HL. Both GGs use a 150 ohm speaker according to the manufacturer. I don't know what the ohm rating on the Vance muffs are but I think the XP headphones for the the Deus are either 16 or 32 ohm.
Google Sergei Upstateny , he tested both and liked the Vance muffs and I think Andy Sabisch did as well.
