I was thinking more of the amount of padding where the new headband on the x series seems to have quite a lot of padding when compared to the 325x.
From what i can find on google the 325x is 356g and the 125x is 260g. Thats interesting as well since the 325x seems to have less padding and about 100g more weight to them. Im looking for as little weight as i can but at the same time all my research tells me 325x is quite a lot better when it comes to sound...
Im also noticing that all the prestige series has this "coin" with model number on the grills. The higher end series does not have that and i see many modded with no "coin" logo. Is that a common mod to remove that to increase air flow or something like that? Is there a benefit to remove the coin?
