The sound signature took some getting used to and initially, the s12 hurt my ears after around 10 minutes. Something softer than the stock tips but with a bore size under 4.5mm might do the trick if you're in the same position (keep in mind these have a smooth nozzle lip)
After about 5 months the left earphone opened. I glued it back together and it's been solid ever since. Apart from that they feel solid and the cable is actually great.
The set is a powerful, fun v-shape. At times the bass was too much for me. I dialed it down with autoEQ (takes it like a champ). After a while the stock tuning actually became less offensive so you can probably get used it too.
It serves your music with some special bass sauce that excels on electronic tracks but it handles genres like acoustic jazz well, too. The bass is fast, nicely textured and punchy (and doesn't lose these qualities after eqing). The timbre is really pleasant to me. I can't hear any of the treble spiciness many have talked about. It does very well in terms of resolving ability, the detail is a half step above DDs in its price range. Mids are recessed, though if you're listening to a bass-light track, it still will sound more than forward and hi-res enough for complete enjoyment. Imaging is ok, you can tell individual instruments apart but the stage is not as wide as on something like olina se. It's a preference thing really.
This set is special in this price category and I recommend it especially if you enjoy your pops and edms but it handles well anything I've thrown at it really. Takes EQ well so you can always tune it to your preference. Probably the most wow factor you can get for the money. Despite some minor gripes it deserves 5 stars.
