Can anyone compare these to Klipsch Image S4? Are the GR07s a clear and substantial upgrade? I have my S4's for the gym, but want something a little more refined, bigger sound, more details and depth for serious listening. I was looking at the IE8 but realized that I simply cannot afford them right now, and they MIGHT be too bassy for me (though not fair to say without hearing for myself). Is it safe to assume the 07s will beat out the s4s? Also, how do the 07s compare to the IE8's? Are they at least comparable in clarity, instrument separation, and midrange? I can tolerate not having the biggest soundstage, but I'm really looking for a phone with superb clarity, timber, and detail (everything the S4's dont have for me), but while maintaining that smooth-ish, musicality of a dynamic driver. Thanks a lot!
