I've been using a B&W P5 as my portable rig for over a year. Love the sound, but find it hurts my ears after about an hour. I recently picked up a HE-400 and absolutely love them as they have started to break in, but I'm finding the open design simply won't work for my purposes. I really like the treble response and detail it brings out in my music. I also noticed a subtle weird left ear/right ear frequency response imbalance when I do a frequency sweep on the HE-400. I mostly listen to FLAC classic rock and jazz played through an iPAD. I do have an FIIO AMP, but prefer the simplicity of plugging right into my iPad.
Can anyone recommend a closed can that sounds as good? I tried the Beyerdynamic DT 770's but found them to be a bit flat. I'm leaning towards the P7s but they are rather pricey.
