this is for resolve xr elite arm too tight and thin issue,
but need more refine 

this is fast draw and depends on your head and how many you installed it may got some sharp edge close to your ears I recommand 3 for each side ,  if use 4 you need sand it a bit

*updated, use edge for inner end (close to HMD side)

and on the side that has cable clip , you need install from bigger side and may scratch your glasses arm. use with caution
