Ordered a pair today - model 500-010 (built in smartphone controls). Paid 170.00, and, took a lot of researching bass centric IEMs before I had enough confidence to click the 'buy' button. Basically, I read through everything I could find on the matter here and elsewhere. This includes the fine work joker and other's have done in reviews, threads and posts. The problem with selecting an IEM (and this applies to any sound output device including amps, speakers and headphones) on research alone (not being able to actually listened to them first) is that to a degree, it is subjective. Of course bad is always going to be bad, no matter who says what, but when you narrow the field down to a short list of qualified candidates, things get a little voodoo. Just like tastes in music itself...people simply have different preferences. I considered many models but eventually settled on the Atrio MG7's mainly because of all that had been written about them - both in posts and reviews. While all of the IEMs on the short list had outstanding things written about them, it was the frequency and quantity of the remarks, and the passion with which they were made, regarding the MG7 that finally sold me on them. That, and input from a couple of people here whose opinions I tend to trust.
Only time will tell if I made a good decision or not, but I am fairly confident about one thing - I now own a pair of kick ass bass earbuds.
