Just joined so I can write an opinion about this iem since i bought it after seeing it received very positive reviews on this thread
I just received mine today and i've been listening in for a few hours now and I do not believe in burn ins so i can say that my opinion is pretty set
Because I'm somewhat a basshead I've payed particular attention to bass while listening to random choices of music on my phone. I must admit, the bass had a pretty weak presence and hardly meets the quote "rich in bass" that they advertise. The songs lost some energy due to the unsatisfactory bass from this iem.
Definitely recessed a bit. This iem is not for you if mid is an important factor to you. Which in my case isn't, but i still was forced to boost mids for songs that needed it.
I was satisfied by the treble. I was able to experience clear sounds, but i can't say it's outstanding enough for this iem to be called treble oriented. I'd say it was OK
Soundstage was pretty good as you'd expect from dual dynamics, it's easy to catch some sounds that you didn't notice on a single driver
I am impressed by the set of accessories and the packaging, but disappointed that no matter what tips i use they just eventually slide off my earholes with the exception of the foam tips
I am also quite saddened because of having driver flex on both sides
If it were me, I wouldn't suggest this ever at a 50$ price and even at the sale price of 35$ since this price range is so competitive that it has wonderful iem that would better sound than this. Hell if you want to be so bored with the sound I'd suggest etykids which is only 25$ on amazon.
