Pros: sound quality, comfort, cheap
Cons: a little to much bass
i actually got the panasonic hje120 but it doesn't seem to be on this website. so this review is for the hje120.
in my opinion they have excellent bass and are very comfortable. the mids are recess and the highs are also recessed. but for $12 i think they are amazing. they actually sound better then the beats imo. this is a good starter iem or for people that just want a cheap solution to portability. highly recommended.
