Pros: Bass, sound quality
Cons: build quality
First thing I have to say is that the build quality is good for the earphone body. The cable and tips are not exactly garbage, but really bad for the price. Case is ok, manual only available in French.
The stock cable is very short, which makes it uncomfortable to wear. I bought another cable right away. Only two pairs of double flange silicon tips are included, same size, lot of flaws. The foam tips however arent bad. All of Shure and Westone tips fit well on these.
Unlike most other BA, these phones does not lack in bass. The sound is balanced with minor boost in the low frequencies. They sounds good all round.
While the sound is great for the price, the build quality is the biggest concern. The earphone body is ok, but you have to get everything else yourself. Especially the stock silicon tips, I actually thought I bought a fake pair, there are just too much hiccups.
