I had purchased this product exactly 8 months ago and till today I am a big fan. The sound quality is damn gooood. The Noise Cancellation is fantastic. It gives a touch of crisp into the sound.
I listen to all kind of music slow, rock, jazz, pop, sad, party etc in this earphones it feels really really good to listen to the music and loose yourself in the moment.
The bass is really good. Believe me you will have great experience listening to Alan Walker' s or David Guetta' s music in them.
They even have microphone and a button which can be used to pick up the call or play the next song in the queue by consecutively pressing the button twice or play the previous song in the queue by consecutively pressing the button three times.
They had 3 pairs of extra earpieces in the box and a premium pouch to carry the earphones.
To be honest I have used JBL, Sony, Samsung earphones but after using this earphones I have become a huge fan of Sennheiser company for the amount of work they do in producing quality sound.
It is worth every single penny you pay.
