I have purchasee ubon headphone couple of months ago from a local shop at rs 300. The sound quality was good with respect to the price. It also had little amount of bass and also had a microphone which is awesome as it avoids noise.
But the thing is that after using for one month it started to malfunction. First left speaker stopped working. After that both the speakers stopped working. It had a 3.5 mm TRSS jack. So what I did was I cut the wire just below the jack and removed the connection from the jack.
I freshly cut the wire a little bit up from the jack and got it soldered by an electrician who took 5 rs for soldering. And yes I saw the connection diagram on the internet then only I went to get it soldered.
And now it has been more than 5 months and the headphone is working great. Only the bad part is the look at the jack part as I applied hot glue to make the wires stick together and does not get disconnected upon bending and stretching.
So I would say that you can also do this trick to get a nice quality sound headphone at such a low price which in my case was 300( headphone) + ₹5( soldering) = 305
