This is sort of a mini review.
 
Overall the sound and build quality are pretty okay. I like the smooth and balanced sound signature these in-ears have. The soundstage isn't too wide or high but it's acceptable. There is sibilance on high notes but with lower volumes it's okay. Bass is not overly powerful but still leaves impact and the mids and trebles are smooth and clear.
 
I like the sound they give, but there are a few things that bugs me. The tips are loosely fitted, they would easily come off or slip off when your not careful. I already lost a pair of them due to my carelessness. You just have to be aware when you put them on or off. The cable is slightly obnoxious and the buttons are hard to click. They're all pretty annoying.

This is my first review, don't know how to express what I hear in detail but I'll try my best, here goes:
 
The overall build is pretty tough and durable. I've dropped mine into water and from 2 meter height (all by accidents, not intended), they're still working fine now. I like the placements of the 3-buttons just under the Y-split. It doesn't put weight on one particular side which is good (some earphones place the buttons to the right or the left or the cable connecting to the driver, which makes that particular side heavier).
 
The comfort is good but the isolation is only so-so. The patented oval-tips felt weird at first but it becomes okay after some time of use. The earphone jack is straight, which occasionally hooks on my pockets when I'm trying to take out my phone.
 
The sound is overall darker and more bassy. I chose these in-ears for outdoor use, which I need more bass due to interference from outside noise. The bass is powerful and delivers really good punches. They also overwhelm the trebles and mids which sort of sucks but it is still within acceptable parameters, especially when wearing them in crowded places, the bass really helps drown the noise down. The mids are okay, but they feel more laid back than the trebles. The trebles are decent. They do have sibilance when playing high notes. The soundstage is slightly restricted.
 
In conclusion, these are bass heavy in-ears. While I don't really like their sound signature when using them in a quiet space, they do help out a lot in crowded or noisy areas. Overall I think they're decent in-ears which might please bass lovers. Now, I rarely use these anymore, only bringing them to school or meet up with friends.
