Yes I will keep the Mobius for now. To be frank, I thought about selling them. They are closed-back headphones and although they are fun I prefer to game on open-back headphones like the LCD-GX because I play a lot of competitive games like Apex Legends, Rainbow Six Siege, PUBG, Overwatch etc...
I also found the LCD-GX to be a bit more comfortable and the mic is way better. I dont like the mic on the Mobius as I need to put it very close to my mouth and end up breathing in it (which can be heard by my team mates) and I cannot control the side tone volume level. Having said that, the Mobius are fun sound wise and I would use them when I play solo campaigns like the new COD: Modern Warfare or when I feel like not hearing anything around me and listening to bassy songs.
The LCD-GX sound clearer, more natural and locating my enemies' position is easier.
So yes, there is room for both in my opinion and if you can afford it.
That was my impression as well fun.... The USB cable connection kinda killed it for me, not to mention the bass. it was incredible and bombastic but after 1/2 hour of modern warfare my ears were shot. Still on the fence if I'm keeping the LCD-GX or loosing my shirt and selling them, I have a pair of Diana V2 on order for a demo... I love and hate this hobby !
