Sennheiser HD650

yes or no?

>Sennheiser
NO!

Hd600 is more neutral thus better

Yes

If you're using them as studio reference monitors then sure, otherwise it's a matter of personal taste

Shit, I forgot the HD650 successor is coming out. Get the HD 660 S

I have them and I love them OP

there's nothing wrong with Sennheisers

Best headphones under $1000 without a doubt

You should always go after the most neutral sound. It's the best for every kind of genre and is the closest to sounding like the original mixing.

If you want a different sound then use an parametric equalizer.

Apo EQ with Peace GUI is 9ne of the best parametric equalizers you can have and it's easy to setup.
