: Great overall balance and tonality. Sounds like a high end multiway speaker. Incredible deep infrasonic bass like a HT subwoofer. Fit and comfort are very good. Lightweight so not noticeable even though appear large. An Amazing sounding sounding IEM.
: I wish the output port tube was longer so that my Comply foam tips could fit. As is, they are too short to hold a foam tip. A case would be nice but if that was eliminated to keep the low low price it's fine.
Update Sept 28, 2017: I found T400 clone Comply eartips on Aliexpress for $3 for 4 pairs and they fit perfectly. The seal is tight and bass just went up a few notches. The comfort went up 2 notches and I can wear them all day with no fatigue. Clarity of mids and treble is also enhanced significantly. Definitely worth it to get the foam tips!
Also, get the upgraded silver or gold braided cables. They don't snag and look very swish.
I was very pleasantly surprised at the sound quality. The overall balance and tonality is neutral with a hint of warm overtones in the midrange. The bass is very full and rich and reaches depths not known to me. Listening to some tracks I heard infrasonic foot tapping sounds of the stage floor etc that was not evident before. The highs are excellent and overall smoothness is good. Soundstage and placement of stereo imaging is very good.
Comfort is excellent. Fit is good but would be better with foam tips. I am using upgraded gold braided cables which were like $13. Great option as the cables are supple and tangle free. The removable 0.75mm pin connetors work well with then flexible wire that is bendable to wrap around your ear.
Overall an impressive budget IEM. Paired with my Pocket Class A portable amp is an amazing combo for peanuts.
Here is the amp I used for the evaluation:
