In terms of music, i always buy sennheiser as headphones for my ipod. I never bother with bose or even beats. Beats by dre has great bass that's true and the noise-cancelling is awesome, but it's never meant as an investment. Common gyud ni sa beats ang durability issue. It's ok if you have a ton of money where you can immediately purchase a replacement but imagine buyng a 22k headset then after 3 months, it's cracked.
Funny enough, i have like 3 sennheiser headphones and none of them cracked.
Maybe if beats by dre can produce durable headphones, then maybe mas worth it siya.
I am however in no way invalidating anone's opinion if feel gyud nimo ang beats but thats just my 2 cents
