“ This IEM is definitely the best bang for the buck! Basshead person should purchase it without a doubt. Even it's higher brother, Philips SHE9800 didn't able to match the sound quality of this IEM! :D It produced very deep punching bass and high definition clarity on mid and treble. It feels like you have your own built in sub-woofer inside this IEM! Comfort to use in a long run,...” --chrone

Among these are the W40, a quad (balanced armature) driver IEM with a 3 way crossover.

“ Disclaimer I bought these about 3 years ago, used them a lot and got to "know" them well. The (sort of a) good thing is: They still perform as good as they did when I first tried them on.

I mean, I based my decision to buy the most expensive earphones I had ever owned solely...” --Checkbox G
“I found these back in last year when I was on the funs of looking for good quality budget IEMS. I was very impressed by these back then, and I put it away for a while. Today, I got back to it, and I thought I better review it, and let more people know about it sound quality Conclusion: At sub 30$ with this much quality is un-beatable. Especially in the sub-bass,...” --Whitigir
