from 5203 reviewsVery detailed sound and wide sound stage
The quality of the product really good and audiostore experience as well
The audio quality was great... And this is the first time I m buying from audio store... It was good experience and it came very faster than i expected !
The resolution of audio has improved drastically due to the balanced cable. The cable makes my Shanling UA2 Plus DAC + Amp to provide more power to the drivers of my Sennheiser HD620S headphones. So, the volume of the headphones has doubled.
The build is solid and the most impressive thing is the flat sound stage.It is recorded to use a portable DAC to get the best sound possible.Not recommended for bass lovers

Good
Very prompt response
It's very good very energetic sound
Audio quality is too good
The fitting and impact of sound quality and comfort is amazing I would love to buy more this kind of eartips
Most convenient

This was a gift for a friend of mine. The shipping took some time but when it reached them it was shipped the same day and after two days it was received. It came in perfect condition. I'll copy my friend's review below:
"This is most balanced IEM with a touch of warmth among everything out there. The Bass is just a bit much and with a 3db high-pass filter it became perfect. It doesn't get much better from this. The soundstage and imaging is decent and competes with +800$ stuff. The tuning, resolution and timbre is one of the best even under 2k. I'm very much in love with them. The comfort is pretty decent. I haven't got tired of them even after long hours."
The audio quality is very crisp and refreshing
The sound just amplified after using this with my kz castor pro IEMs....it is amazing.

Great product, strong magnet and holds the DAC snugly. Wish the 3M sticker was sold separately as well as already started to come off (user error).
