Hi you Head Fi's,
I purchased a MDR-EX700LP here in Panama form Sony Center for US229.00 + 5% tax. I own a SuperFi 5Pro which I had to send to UE in warranty because of a cable and cable socket issue. Fi5 I like them very much in use as IEM when playing Bass Guitar with my Rock and Salsa band, but listening to my iPod Nano 4GB 2gen, I felt that I needed a little more treble. I use treble boost in the EQ, but then in certain song there is a little lack of bass. So I wasn't 100% satisfied. With the MDR-EX700, I'm very satisfied with the bass they produce and the hi's are much better now. They feel more open and wider, sound stage wise. The Fi5 have a good tight bass, but the Sony's go lower in the frequency range without getting muddy and produce an excellent low mid bass. Sony say that they go down to 5Hz, which I don't believe but the sound like the have a sub woofer on so it could be. Compared to the Fi5. I can hear more detail now. The mids are excellent, the voices the guitars, the pianos, everything is there and very well balanced (I listen to a lot of Rock, Jazz fusion and some older Salsa music). On the bright side, I would say, the treble is good, not perfect, but good. The cymbals and Hi hats sound quite natural and brighter than the Fi5pro. I had the opportunity to listen to the Shure ES530 and would say they compare a little, but the Sony are brighter and for nearly half the price, the Sony MDR-EX700LP is a much better buy. I likes the bass and mid's of the Shure, but like the Fi5pro, they lack treble. Both sound very warm, but a lot of songs need this extra treble the EX700 deliver. I really don't know much about burning in time, but out of the box they sound very good. What I don't like is the J cable, which I changes its form with a little tape and created a Y without modifying any cable connection and it work very good. I would have preferred the cables going over my ears, or the use of both ways. In live playing, it is more comfortable to use them over the ears. Not that it is not possible, but in this position the casing of the phones make a little uncomfortable pressure in the outer ear.
I really do like these Phones, and for the price it's a steal.
