Pros: Idioticly clear(analytic but not boring), real nice mids and high, deep bass. Great looks.
Cons: Have had a few dropouts in the beginning, not anymore.
So I've owned a pair of these for a good 2 weeks now, and never leave the house without them.
I've owned a pair of bluetooth Sennheiser MM100 headphones before these for years, which where pretty good, very good even. But I sold the MM100 within 1 week, of owning these MDR1RBT's. The MDR1RBT's simply blow the MM100 out of the water.
The sound is simply amazing, no matter what kind of music I play. Gospel, country, rap, techno, classical, rock, dance, jazz, you name it. My taste in music is very broad, and these headphones seem to adapt to what ever type of music is playing very well.
I am suprised by how good it sounds compared to my wired desktop setup (o2/odac special edition from Mayflower+ HD650's).
The difference is noticeable when I switch from my desktop setup to bluetooth on my GalaxyS5+MDR1RBT, but only barely. And that is some high praise, right there.
As expected, there is no need for an equalizer, because there is no real weakness , when it comes to low/mid/high on these headphones.
The downside, however small it may be, to me, the leather earpads are less comfortable then for example cloth earpads, but these can be swapped I guess.
Using the controls on these headphones does take some getting used to, but, once you've learned where every button is, it is actually really pleasant to have controls on the back of the headphones when you wear them.
