Fantastic IEM

One of the first IEMs I bought and the favorite out of the 8 iems I own. My musical tastes change daily, hip hop to classical, movie soundtracks to heavy metal, the MS4 handles it all with ease. Vocals are clear, female or male, just gorgeous. When I review an item its an item I love, and I also try to be realistic. Which means I force myself to find a flaw. After a few minutes the only item I could come up with is the bass slam for certain types of music is a little "punchy" than my planar headphones, or my BQEYZ summer iems- which thunder on certain drum tracks. Lastly, super easy to drive. Running it through the HIDIZs dh80s amp/dac - wow... great combo. To summarize them; make a playlist of various genres. Sit back in a comfy chair, with a nice USB dac/amp. Close your ears and get lost in the music.
