Trying to decide the best headphones around $100-150. I've never owned full size head phones but I have had Senn cx300, shure se110 and now have Shure se215 IEMs. I've read a lot of good things on the forum about the m50's and the srh750's. Not really sure which would be better though. Also a lot of those threads were old, not sure if there are other contenders I should consider. I listen to all sorts of music but mostly various genres of rock, pop punk, some rap. I tend to like things slightly bass heavy but still want a clean sound from highs and mids. I also use headphones mostly at the gym or office. I guess I would be using these at my office or at home. Not really sure. I really would like to try some on in store but not sure who in my local area has any of these. I know best buy doesn't for sure. I'll primarily be using these with my iPhone listening to music on Spotify at 320 or MacBook. Thanks for any input.
