Summary: My main purpose of this review is to prevent other people from making the same mistake like me. Well, I was looking for a new pair of earphones for my collection. I never had a pair of Pioneer earphones before, not even try it.. So, I was interested to buy it, attracted to its packaging and considering that Pioneer is one of well-known, professional audio stuff (such as home theater and speaker) manufacturer. Besides, the earphones itself is good-looking, well designed.
