I'm looking to get a new headphone because my Sennheiser CX500 have died after over abusing the cord. The thing I'm most concerned about is the bass. I wand it loud, crisp and clear. The earbud candidates are: 1. Shure SE310 2. Monster Turbine 3. Ultimate Ears super.fi 5 The headphone candidates are: 1. Monster Beats 2. and I have no idea... Does anyone have any experience with these devices? Which one has the best base? If you have some other suggestions, feel free to add them. Thanks.
