Buy only Sennheiser as they give 2 year warranty.
lol you must be kidding!! skullcandy iems are crap and sennheiser lower budget iems are crap as wellI think you should go for Skullcandy S2FFFA-257 50/50, Sennheiser CX 300 II Precision. I using Skull Candy In Ear Headphones. This one is the best from my side. I purchased it from Snapdeal and get better warranty option.
Me and my friends earphones don't last that long. No physically damage but they usually get damaged from inside. 2 years warranty is a good thing even if it comes little expensive. Its still cheap when compared against buying new earphones every 5-10 months. That's why i go for them now. And their sound quality is also awesome.Sound is quite subjective & never judge the quality of SQ by its price. Just because of warranty it does not make them better sounding over the others. There are many quality IEM's from china which can beat costly Branded stuffs. eg. Soundmagic, T peos, Vsonics & not to forget Xiaomi Pistons.
No doubt sennheisers are good especially warranty policy but what I remember from my last reading over the net that ppl on international forums compare Havi B3 Pro 1 to Sennheiser IE60 & IE80 which are around 12k & 24K inr respectively. In fact Havi excelled in some genres.
I personally had auditioned one sennheiser momentum on ear worth 13500 inr few month back but did not find any extraordinary SQ improvement over my stuffs which cost mere 3k inr. Finally it boils down personal preference.
BTW nothing personal here bro...
The brands which I listed have very good quality too except few soundmagic models. Check out t pros popular built quality, its as good as any reputed brands.Me and my friends earphones don't last that long.
