I have purchased this 2 months ago first impression is that its build quality is awesome and it got tangle free wire so its good and sound quality is awesome
but its fit in my ear is a little problematic
its hurts a little and needs a lot of adjustments but once fit good experience is awesome
warranty is of 1 year so thats good also
and brand trust of jbl is very much
i compared this with sony earphones I found this one more good so go for it
