I would like to give a 5 star to this product, straightaway. These are one of the best earphones you can get from JBL, without burning a hole in your pocket. It feels royal to the eye and comfortable to the ears as it grips in perfectly. Carrying it isn't much of a hassle as it fits in smoothly to a bag or pocket, without worrying about any physical damage. Bass and treble are probably the best in the given price range. Very useful for people passionate about gym, running or any activity where pleasure can be derived from the music.
The quality of JBL comes into play in hoarse traffic, as it has excellent noise cancellation qualities. No outside effect of the incoming noises, which gives it an additional advantage to pick upon among all JBL products.
It's a definite buy in the 5k range. Go for it, even with closed eyes.
