Disclaimer: I am really new to hi-fi so I won't judge the sound quality and signature (as I feel not qualified enough), though I can evaluate the build quality, package and fit. This is my first review.
INTRO
I decided to buy them as an addition to buying Tennmak Pro Dual Drive. They cost approx. 12 usd for normal package (not bulk one) inc. Ali standard shipping, which is imo a good deal. As I ordered them I was almost immediately contacted by Tony saying that the metal box is currently replaced with black pouch. I was okay with that.
THE LOOK
The look of them is really good - they are made of metal (probably alluminium as the vendor says - they are very light in terms of weight) + covered in paint that feels lika a porcelain when you touch it. There are no gaps, no holes, except the ones that were designed to be
The cable is flat and looks ok. The mic is good, worked fine with android.
SOUND
I used them with xduoo x2.
Only thing I gonna say about the sound is that the stage is rather narrrow, however, what really compensates that is the isolation.
I live in Moscow, Russia, and I use the subway ( or Metro, call it the way you like) everyday. Listening to music in this environment can get tough: trains are loud as hell. What I want to say is - when I put Porcelains in my ears with whirlwind tips I stopped to hear anything. Ok, not anything, I barely heared the trains. Note that result may differ based on ear form.
SUMM
Generally when you buy earphones below 15 USD, you do not expect much. However this one is a solid choice if you do not want to spend days and nights picking the earphone that costs less than the bottle of booze.
They have good package: 2 sets of tips (whirlwind +normal ones) and carrying pouch + the delivery is free.
All of that for 12$.
They surely suit you if you are looking for cheap IEM to use while going to work and back.
p.s. I do not have them right now (maybe I get some photos a bit later, as I need to get to person whom I gave 'em to). I decided to stay with Tennmak Pro.
p.s. Some photos added.
