Bose QC 15 or what? Cannot decide.

I'm in the market for some decent cans. I had the beats because that's what my girl got me and I also had the sol republics. Hated them. I'm eye balling the skullcandy mixmasters and the Bose QC 15. A buddy told me to investigate the soul by ludacris but I've lost faith in products rappers put out. Here is what I want.

1. Vibrant sound (bass, mids and highs) because I listen to everything from rap to rock to dubstep to old school jazz, etc. I listen to everyone but opera.
2. Look decent. I don't want something like a helmet on.
3. Decent noise isolation (noise canceling is nice but I want my headphones to work after the battery dies)
4. Not so bad sound leak. (girlfriend always getting mad at how loud i listen to stuff)
5. And I know it's random but i like the single side cord. The cord coming out of both headphone seems to tangle.

Thoughts? I kind of been considering the 3 listed above.

I've also been considering the AKG K550. Thoughts on these as well, please.

I dont HAVE to have it. I would like at least some form of noise isolating. I dont really want to be able to hear everyone and have them hear what I am listening to. Does that make sense? But obviously, I dont want to sacrifice sound quality. 

So this is gonna sound a bit off, but I'm sort of stuck as to where I can get the headphones.... My lady bought me the Beats at Best Buy and their return policy is dumb. So I am being forced to exchange in their store within 30 days. That's why I brought up the headphones earlier that I saw at the store. I do apologize if this closes the gap quite a bit (which i know it will)

With the gap being so closed, I am really leaning toward the skullcandy Mixmasters. Here is why.

1. Don't want to have to carry extra batteries with me at all times (one of my biggest problems with the beats is that it needs batteries to work)

2. I'm growing more and more against headphones endorsed by artists (Ludacris, Dre, Bob Marley, etc.)

3. I have read pretty good things about the skull candy Mixmasters. Granted, the skull candy brand isn't synonymous with high quality. 

 

I'd like to be knocked off this high horse if I am just that, HIGH with a false sense of what I am getting into. 

Here is the list I got:

1. Beats Series

2. Soul by Ludacris series

3. Bose QC 15

4. Fanny Wang 3000

5. Skullcandy Mixmaster

6. AKG K550

7. Audio technica  ATH-ESW9A (breaks my single cord thought, but unsure if it is worth it)

8. Pioneer SE-MJ591

9. Audio Technica ATH-A900X

10. Allen and Heath AH-XONE:XD2-53

11. beyerdynamic AMS-DT-770-PRO-250

12. Bowers and Wilkins P5

13. beyerdynamic AMS-DT-1350-80

 

 

thoughts?

I am open minded to the idea of needing a battery, but I'd like to avoid it if I can. 

I was looking as to what available in my area. I leave for vacation Saturday and was hoping to exchange for a pair tomorrow. Unless you have a pair that I havent listed worthy of a wait. 

I also stuck to the price that she had spent, which is $300. I am always open minded to something that is lower priced and will out perform something that is $300.
