Hey guys, I bought the MDR-1RBTMK2 after lurking through this forum and reading a bunch of recommendations for a good bluetooth set. I started with the Beats Studio Wireless and the Sony MDR-1RBT "MK1" - bought both from Best Buy to have a little trial period. Long story short, the Sony's ended up being right for me, and I wanted to get the updated MK2 set. I imported a pair from Korea and received them last week.
I did the same thing, bought the Beats Studio Wireless and then just got the Sony MDR-1RBT MK2. I had a different experience with the two. I can't believe I'm saying this but I think I like the Beats better. They are both extremely comfortable headphones, look great, and pair easily with my macbook and iphone. To my ears, they also have similar sound signatures.
They both put out extremely fat, punchy bass. The Sony's bass seems more controlled, but hits just as hard. I love the bottom end of both of these headphones. My only problem is that everything else from the Sony's seems to take a back seat. With the Beats, you get loud bass but you also get loud vocals. Everything is thrown out at you, so in a way it all seems...balanced. Not in a tonally balanced, neutral type of way, its almost hard to describe. With the Sony's the bass is prominent, they move a lot of air, but everything else seems distant. This makes for a headphone that doesn't sound cohesive.
I'm hoping that an overnight burn in will help the rest of the sound open up a little bit. But as of right now, I'm thinking about returning the Sony's. I was really hoping the Sony's would be the complete package for me because the slight hiss from the Beats' active noise cancelling drives me crazy sometimes, especially when I'm watching anything with just spoken words.
