My wife just did a run-through of my headphones in a comparison to her beloved B&W P5. She didn't like anything I had until she listened to the Shure 1840, which she loved. But she wants a very compact portable, preferably closed and small like the P5, but with much better sound. Is such a thing available at any price? She did not like the v-moda M80 for example. Price is no object, but has to be small, not stick out like a Martian helmet, and sound really top notch - very hi-fi, but not bright. All of these requirements are critical.
