I thoroughly enjoyed your review @enamul17. Honestly, I have used many earphones because they make the sound quality to really come out.

the earphones that I used earlier did not last long. All were spoiled after about two-three months.

This is the same issues we face in my place. many of these earphones are of poor quality. They are mainly made in China. But when you get a superior product, it will definitely work beyond 2 months.

Also I mostly listen to radio so this earphone is very useful for me

Most radio signals will not be received without an earphone. This is another reason I usually carry my own anywhere I am. Thanks for writing this great review.
