Kind of changed my mind now, looking more for a good set of headphones for $100-150 with a decent mobile amp that isn't usb. I'm talking more along the lines of being able to hook it up to my MP3 player or phone mobile. In all looking to spend around $175-200. Sound card is gonna wait until I can get new speakers first.
Was looking at this one
I haven't messed around in this field at all really, so any advice is extremely helpful. Used to just using my cabinets in my living room for music. Looking for a more on the go and home use set of headphones now. I'm not sure of the difference between close ended and open other than open is meant for home use as it allows more sound in/out and allows for higher vibration of sound so mids and highs are better.
Keep in mind these are for music only.
