A nice IEM for the price, just not on Drop, as someone already said, find elsewhere.
Sound is similar to the Seed Yin, ironically, considering this is cheaper, personally & subjectively, I enjoy the Sif's sound tuning more though I do like both IEMs.
The only minor issue I find is the stock cable isn't exactly wearer friendly & some may find it a little tight though given the price, not really surprised.
Also, for those extremely sensitive to highs, stock cable may enhance any source recordings with lots of information in that area in frequency range.
I would suggest finding another cable though the cheapest cable I have found which works nicely for both comfort & sound with the Sif is ISN Audio C16 which is worth more than the IEM so go figure.
Hope everyone has a great day !
