Fantastic midrange, it's really well done
Covers all of sound spectrum well
Forgiving on bad recordings
Solid and textured bass that doesn't overpower the midrange. Bass to midrange balance is great IMHO.
Memory wire is a PITA and causes microphonics if not situated perfectly
Lack of micro details
Treble is not bad, but not on par sq wise with the mids and bass.
Gives a "in head" soundstage
It was a PITA getting a sealing tip that worked with the housing design and over the ear memory wire. I had to use an olive tip from another set of iems.
The pros far outweigh the cons, and opinions could change the more I listen to them.
