Now to the PM-3's. So, after testing all of the above I decided to try the PM-3's again based on all the newer reviews since I had purchase them back in July. Well, I have let them burn in for 24 hours and they are just amazing cans. I find they sound better with audiophile music with the amp but they are not bad even with the iPhone and no amp. The bass shows itself when needed and some say the highs are subdued but I find with the vmoda amp the bass and highs come alive. The mids are spot on. I have used my mac as well with audiophile music and they sound awesome. The soundstage is small but very clean. I slept the last two nights with the PM-3's, fell asleep and woke up in the morning with music still playing with the cans still on my head without any pain and actually was nice waking up to quality music on my ears. Some might say the cans are a little tight but give them a chance and you will find that they find there way to become more and more comfortable as time goes on.
