This is a cheap rip of Samsung buds and lacks functionality in all possible ways. To begin with, user manual is thrash and wrong about manything written.
The fit of these buds is sort of comfortable but takes a while to get used to. The touch controls are not accurate and they have no use if you have any intentions of pairing these to any computer. Sound quality is balanced nothing to greatly appreciate.
Now for some unacceptable things. There is no ways to reset pairing on the buds itself. So basically you have to unpair these from the paired device. A measure for this is to take the device away from the paired device and then open the lid of the case.
Also if you connect this to a pc it's volume is not controlled by windows volume control and rather by individual application. This very painful as you have to adjust volume in the application individually. This is not observed in mobile. There is no noise cancellation of any sort.
Mic quality is basic and accetable as long as you are seated in a quite environment. Also another annoying things is the presence of flashing red and blue lights when not paired.
Verdict: You can get better tws of brands like boat (in india) in this range. This is people who want to have a clone for showing off and who cant go for real buds.
