I would really like to get your opinion to help me select one of the four headphones mentioned. Been reading alot about them and they all mentioned great things but relatively all execpt for the M-80s tend to have negative comments too. Not saying the M-80s are perfect but these are pretty much the headphones that seem to have more consensus over all with the fewer negatives I've read. I will mainly use them for air travel, exercise (weights and running on treadmill) and some light use on weekends lying on a chaise lounger. Now, having said that, this compromises my commitment for the M-80s because the M-80s seem to be too big for air travel. If you want lean your head against the window or tilt your head to one side to try to fall asleep I think the M-80s are going to get in the way and make you feel unconfortable. Wearing these at the gym don't make sense either, but if these are the best I can get I'd sacrifice the gym. Really wanted to get the M-80s but for my use the other three tend to make more sense. Isolation is not THAT important since I do kinda like to be able to hear some of my surroundings. If flight attendant is talking I'd like to be able to hear them by pausing the music without taking a headphone off. This is not a must I can go either way but if I had to choose between two and all else being equal I'd lean for less isolation. I do like bassy sound but not to the point were it kills everything else, but do have a preference for very warm bass you can feel. I also do like the mids and highs not to fall behind and overall clear sound. I am going to use these from my iPhone and iPod and need the remote and mic. I was basically into Classic Rock through out my life but have been finding alot of interest in Electronic, Chill Out and Dance music now. Like the Black Eyed Peas too. I don't live in the US but am going next month and would like to have my mind made up to buy one of these. I know that these are not all in the same class but this is pretty much what I have on them... 1- M-80s: are on ear and don't offer much isolation. Excellent overall sound with good bass. 2- Shure SE215: give great isolation but the bass is not as heavy as the others. Also read trying to get them on is a bit more time consuming and tedious than the others. 3- Bose IE2: I tend to try to stay away from Bose cause they're marketing hyped but have read good things about these. They are more bass heavy than the Shure SE215 from what I've read but don't undestand how they achieve this being that they are not inserted into the ear canal and don't offer isolation like the Shure SE215s do to get the bass. 4- V-Moda Vibrato: the bass is very good on these. Mids are good and lacks a little in the high departement. They say isolation is good. Some have commented that the remote and mic tend to break down relatively easy and that the remote is on the small side. Others say they had problems losing sound out of one of the sides withing a couple to 9 months. OK that's pretty much it. I'd really appreciate any help I can get withing these four unless there is one that I have overlooked that I should seriously consider but if not I'd rather make my decison within these. Thanks in advance.
