I have several earphones and headphones and also tried wireless in last 5 years and experienced on how to buy earphones. I have used brands like Samsung, Micromax, Apple, Philips, Xiaomi, Boat, Nokia and many. I purchased Neck band earphone of Philips which is having circular cross section wire and my first advice always try to avoid circular cross sectional wire and try to find out Rectangular cross sectional wire because those are tangle free and life of those are much more than circular one.
Another thing which I get to know this year that always check that the 3.5mm plug must not be straight, it must be at 90° with the wire which is also called bent head 3.5mm plug.
Third and the most important feature which I notice is noise cancellation feature and bass. Only checking description is not enough, I always listen and take a demo for checking noise cancellation and bass of the earphone.
Some earbuds are extra large and some are small, so choose earbuds as your needs whereas I prefer medium sized earbuds and it fits properly in my ear.
I would suggest one perfect earphone with microphone of Boat In Ear 225 Extraaa Bass earphone which is perfect under Rs.500 earphones and can compete with Rs.1000 earphones too. I too personally using it from 6 months and having no problem with. Easily available on Amazon and Flipkart.
