Most headphones use power in the order of mW (milli-watts). So any onboard sound/soundcard should be more than capable of driving them.
(Before someone points out, there are some high-end / high-impedance headphones that do usually benefit from an amp but i guess thats not relevant here)
Another side-note, the ear-phones you’ve linked to might have very short cables so unless your cabinet is near enough they may not extend far enough.
Its just goin to fit in…but 1.5 m would have been better
How big is CX 300 cable? They say Asymmetrical, L: 170 mm; R: 510 mm, (850 mm divider to plug) I s’pose that means 1.02 m from left and 1.36 m from right ?
they all share the same drivers (i’ve heard at least half of them and they all sound the same )
they cost between 200 and 500 Rs . The sound quality is the same for all. just the construction of the headphones change. long cable , metal headband /foldable construction etc
