Most of us here believe that it is quite easy to beat (pun intended) the sound quality of Beats--and for much less money. From what you posted, I would guess that you are looking for a bass emphasized sound signature, but for clarity, please tell us:
What equipment will be powering these cans? Will you be using an amp?
What is the format of your music and other sounds you will putting into these cans?
Describe the sound signature that you are seeking?
What music genres do you plan run through these cans?
BTW: asking for no plastic and light weight might be going a bridge too far.
Sorry I was disconnected by my ISP for a week that's why I didn't answer. Ok so I'm basically looking for all rounded all purpose clean sound. No enhancements, just the way it's suppose to sound. I'll be using for music, gaming, movies, webcam, etc. eveything.
And regular use with standard devices no amp.
And yeah ok just really sturdy and lightweight and everything I mentioned previously. So now take everything into consideration.
