I have been using the xba-h1's for about three days now. I am no audiophile, What i am is someone who loves music and knows what good sound is. My past collections are piston 2.0, xba-3, shure se-215, klipsch x10, klipsch s4, v-sonic gr07, Among others and i have found these to be one of my favorite headphones. But there is something weird about the sound as a whole that i cant point my finger at. I know that i wish these had a more expansive soundstage. The treble could use quite a bit more extention and the mids i wish were alot more airy. Instrument separation is pretty impressive. Im still on a search for what is the perfect IEM for me, and have been for a long time. For now these are close and i enjoy them. The bass is very much present and definitely not boomy. Which i love! I would definitely recommend these to anyone who can get them under $90 like i did. The reason for my low value rating is because i know from what ive read on this website you can get better IEM's for this price range all though i have yet to find them, i have a limited wallet and cant keep buying earphones. If i could i would.
