The UE 700, is a very neutral sounding iem, that I often find myself listening to despite having higher-end headphones such as the triplefi 10 pro and the ultrasone pro 900. They have a very rich sound, with very deep and textured bass, although it's very neutral bass, so these aren't for bass-heads. The mid range is also very neutral, but sounds somewhat recessed due to very bright highs. They aren;t sibilant, but nonetheless very bright. The soundstage is vaste and like the triplefis, they manage to have a very large sound with revivals full sized headphones. I haven't tried that many iems, but from what I've heard UE is the only brand that can make iems sound large. The isolation and comfort with the complys is superb. They are so very durable looking (highend UEs always are), however cable isn't detachable. You might be able to snatch a bargain and get the Triplefis for around 150, but you'll have to be lucky and patient
