hd6 is similar stuff.

yeah , but sennheiser , beyer, sony ,

these company is more popular than other brand.

I like hd660s , but the treble is not my taste .
So , that's my change.

Preamp: -7.9 dB

Filter 6: ON PK Fc 3600 Hz Gain 1.7 dB Q 2.000

Filter 7: ON PK Fc 4800 Hz Gain 2.2 dB Q 2.000

Filter 8: ON PK Fc 5700 Hz Gain -1.8 dB Q 1.100

Filter 9: ON PK Fc 8400 Hz Gain 5.5 dB Q 0.900

Filter 10: ON PK Fc 17000 Hz Gain 7.3 dB Q 2.000

hd560s is pretty good , but need good recording , that's why they made it as the HD400pro.

hd660s is actually at different level, even with shit quality recording , its still sound good .

you might notice the bass of 560s is way different.

holy shit

gaming headset isnt bad,but expensive price and shit quality are problems.
