Superlux HD-668B v Sony MDR V6 v Superlux HD-681 (Advice required)

Hey guys, so I've been lurking around the forums since I started looking for new full-size headphones, and I've pretty much narrowed it down to these 4. However, I'm not quite sure as to which one would suit my needs more. I'm by no means an experienced audiophile. All my previous phones have been pretty heavy on the bass (cx-300-ii [RIP], Brainwavz pro alphas [RIP]), and I've been meaning to try out more analytical sounding balanced headphones. So yeah, my question is really which one of these would be better for a person new to analytical sounds?

Feel free to suggest others, though preferably not more than £50. I'm on a budget here :p Also, I tend to go through headphones quite fast hence, the unwillingness to splash on expensive ones, so durability would be a relevant factor. 

p.s. not sure if this is relevant but other headphones I have in my possession are the koss portapros, Audio Technica ath-sj5 and the Brainwavz M2 (yeah there is a pattern in how i pick my earphones :p)

Cheers

Oh , I listen to quite an eclectic mix of music, it used to be predominantly rap and metal but I've branched out into orchestral and acoustic indie and live performance recordings recently so I've been looking for phones that would give me better clarity with those. Also, my setup isn't complicated I use a rockboxed sansa clip+ and my macbook pro. Nothing fancy. Although I wouldn't mind spending on an amp depending on future needs.

 Hi yes I did actually read your review on the 668B and the 681F. It was helpful but again, the main concern I have about the 668B and the 681F is the lack of bass. I'm looking for analytical phones without exaggerated bass yes, but I'm not sure I would enjoy phones that just have no bass at all. From the reviews I've read about the 668B, there seems to be disagreement about the bass quality on it. Also, you place the 681F below the 668B in terms of bass quality, so does that mean that these are severely deficient in the amount of bass?

Also, it'd be helpful if someone could do a direct comparison between Superlux 668B and the MDR V6. From what I see, the mdr-v6 seems to be established entry level industry standard headphones, however, I'm not quite sure about its looks :p so I was wondering how it sounds compared to the 668s. The sr850s were included mainly because they use the same drivers as the superluxes and they're even cheaper. Problem is do they sound better as well compared to the 668/681s?

Thanks! For now I think I'm leaning more towards the 668Bs and the MDR-v6s. It'd be really helpful if anyone could make a direct comparison between the two :)

So yes, I read joker's extremely helpful thread but there is still one more detail that I need help with. Point is, that I'll be using these for casual listening and I don't actually do any studio work. Joker mentions that the mdr-v6s are well suited for casual listening while also asserting that sound signature of the 668Bs are cooler and more analytical, and harder to drive. Does this mean I'll have to pair it up with some warmer sources to get a better sound?
