The sound quality of these is excellent. I have the KZ KAX for comparison and the bass is better than that.
Pros:
Looks very stylish.
The fit is good and can wear for hours without noticing it.
Sound Quality as I mentioned before, I don't know how to describe it in audiophile terms but I like it very much.
The stereo effect is awesome
The touch controls are very sensitive and work well.
You can wear these for hours and there is no fatigue from the sound.
The charging case is good and is also stylish. In the images, it looks big but actually, these are small.
Cons.
The connectivity and connection are not perfect, there are a few hiccups once in a while.
Overall for the price, I think these are very good and definitely worth the price. KZ impressed me on this one, but I hope they improve the connectivity and battery issues in future models. (Although this is not a deal-breaker, I just expected a little more that's it.)
If you are looking for TWS earbuds at this price range, I would definitely recommend this because the sound quality is too good.
