Here is the funny thing. Someone else said the didos werent cannons and xanlamin stands by his opinion but some reviews call the dido as having tons of bass. Then gelocks says they are not as bassy.
I want to clarify something that I am learning about headphone bass. I will use my recent comparison of the yamaha vs q40.
The yamaha is not a basshead headphone but when it calls for it will smack and punch like one. Okay then you have the q40 that is a basshead can and the mix of it always makes the emphasis/focus the bass even though it is done really well the bass dominates. However when playing two really bass heavy songs the yamaha hits and rumbles a little bit harder than the q40.
Something else to confirm this is how the hd 8 dj is. It definitely has more bass emphasis than the yamaha. Well xanlamin said the yamaha rumbled more. Was he off to my ears? No The hd 8 dj has more bass than the yamaha but the yamaha housing lets you feel it more in the cups. Well the hd 8 dj bass dominates the mix more though and is truly a basshead can.
Another thing is how people say the spirit pro is more detailed in the bass than the 7520. Absolutely not. the 7520 is more detailed but the pro sounds more controlled.
thump equals bassy
bassy equals thump
tight equals detail
impact equals bassy
impact equals thump
what determines what is bassy or not, impact/rumble or quantity lol? That is the question for now I will say it is the balance of the headphone that determines for me what is bassy or not. But then you have this PANDORA whose bass is not the main emphasis but punches harder and has just as much weight to it as any of the above. Yet it feels like the bass is free and not holding the music down but rather boosting it in energy.
I am confusing myself so sorry if I confused you.
