Query: Pro opinion...

I have been a musician for over 30 years, built and operated PA systems, worked professionally as a sound man and have spent a lot of time in studios, I know what I am listening to.These were better than the trash that comes with most MP3 players, but they really were very underwhelming, the bass was non existent in my opinion.Save your money, go to walmart and buy the $16.00 Phillips"virtual surround" vented ear buds, they are much better unless you want total isolation. I don't want isolation, I would like to hear the truck that is about to run me over... But all that aside, the Phillips were the best out of 5 models I tested including the V-modas.
