I bought these in early May based on nearly unanimous recommendation from people on a bunch of websites, and I must say they don't live up to their reputation. Some of the common things people pointed out were that they are excellent for the price, they have great mids, and they have bad build quality, the bass could be better, and that they are great for all genres. Most of these points definitely stand up, I don't think I have ever heard better mids in my life, they are fairly cheap, but to me they have nothing else going for them. The bass isn't just leaving more to desired, it is so bad it makes some genres hard to listen to, it is almost comically weak, more like a tickle than a punch. They aren't especially neutral, they are just very mid heavy. I guess it sounds neutral at first glance, but the lows are extremely recessed, and the highs aren't very sparkly, they also have bad sibilance in a lot of cases. It is basically the opposite of the classic "V-shaped" sound signature, whereas normally mids are recessed and there is too much emphasis on lows and high, these have way too much emphasis on mids and bad lows and highs. They also definitely don't work for all genres. When listening to classical instrument seperation suffers, soundstage seriously suffers, bass suffers, highs suffer, and volume suffer. For metal the vocals are amazing but a lot of the rythm is lost in the weak bass, funk is amazingly smooth and probably the best genre for these, for techno in general they are terrible due to the bass problems, although as usual vocals stand out and are excellent. 
 
In terms of physical qualities they aren't great either. They look quite cheap, which is the downside of their otherwise nice minimalistic style, the 3.5mm jack is very obviously low quality, as someone who fixes headphones on a regular basis that stand out like a sore thumb, the cord definitely also feels a bit flimsy and I don't expect it to last long. If you don't wrap your earphones around the back of your ear these suffer from constant annoying microphonics leaving you with no obvious choice except to wrap the, but they also have a tendency for the wire to constantly fall off my ears, which can get very frustrating at times. The sound isolation is mediocre, nothing really to complain about but also not worthy of praise, I often have to bring the volume up a lot compared to where I normally do with IEMs. The choice of included tips is strange to me, there is a bunch of flanged ones that scratch and irritate the inside of my ears, there is ones that are way too small, ones that are way too large, and only one set that is similar to what is normally included with all IEMs which is medium sized rubber tips, but it's still not exactly the same it's like a half flange, the tip is two different sizes but it isn't separated, 
 
In conclusion, I definitely do not recommend these earphones. I have had 40 dollar Sony earphones perform twice as well as these for less than half the price, and they lasted me almost 2 years, where these apparently have a tendency to fail after only a few months. These are an exceptionally mediocre pair of earphones with a huge list of major downsides that are only redeemed at all by the excellent mid range performance.
