As a person who enjoys quality audio but does not necessarily want to spend a fortune, I thought this might be a good iem to try. Both in terms of this particular unit and IEMs in general, as before this one I never owned a real IEM. I was pleasantly surprised about the neutral sound with slight bass bump. These do not strike me as too analytical and fit well for my purpose - wearing them outdoors while walking, where the little extra bass helps.
The fit for me is excellent! Of course, this will vary from person to person, but the first time I put them in, I thought someone has made these for my ears specifically. My left ear is slightly different shape than the right one (or other way around?), but the overall shape of this iem and the ear hook ensures the best fit of any earphone / iem I've tried before or since this one. Build quality seems good and the cable is flexible.
I would have liked any sort of carrying case/pouch. I'd pay extra for an option to select it while getting the IEM.
Cheers
