My X1's also weight 362g as well ( Thats a surprise
) My cable is 40g on top but its not stock)
They do not feel heavy while wearing however .
Foe example HD650 with 10ft Stefan Art cable weigh 414g and feel the same as the X1 weight wise on the head. However Beyer T1's weigh 528g total and do feel a little heavier.
The only problem I have found and previously posted is my ears are somewhat large and feel a little constrained within the Cup .
HD650 cups have a larger and more oval hole and a better feel against the sides of the ear itself but don't sound as good as the X1's.
Beyer T1 has a larger round hole in the cups and also feel better as well . Sound wise they are as good as the X1 but have a different sound signature and cost more than 3 times as much!!!
My DT 880 are right around that too even tho cib felt they were heavier (also without cable). Apparently Philips' listed weight on that PDF pamphlet is just way off tho, even with the cable it doesn't reach the 430g that they state.
