I received the M100s, and used them for about a year. While the evaluations of balance that I've seen others make, with regards to lows vs. highs, are pretty accurate - I found them to be excellent "workhorse" ear buds. Fun to listen to, and more than adequate for daily listening.
However, after a certain point, the buds became unbalanced. Made sure that it wasn't my device(s), and verified that it's the buds. I could compensate for a while by adjusting balance - but it got to the point where I had to reduce volume on one side by more than 80% to come close to a balance.
Brainwavz was willing to accept a return, but because I'm in the U.S., and the address to which returns are sent is in Hong Kong, it would cost more than twice what I'd paid for them just to get them there. In fact, it'd cost more than a new pair of them via Amazon. Were I able to return them at even around $20, I'd rate with 4+ stars (particularly the Blue Box deal) - but all of these issues combined make for a reasonably solid IEM with a pretty firm lifespan of 1 year for U.S. residents.
