Kit 1 is on it's way to
@guani360 - Port Saint Lucie, FL.
Very brief thoughts, I've owned the W500 for a few years, they have given me hours and hours of enjoyment. The W900 is on the next level. Bass is controlled and just right, but extended, on the W900. For bassheads, or the occasional one, the W500 is really where to go. Otherwise, the W900 is a worthy addition to any high end collection, the sound of which reminded me of my Noble encores.
I've also owned the original A3HPro for a couple of years, buying it off of Massdrop when it was first offered. V. 2 of this, which is the current tour earphone, has bigger and better bass, could it be using the same bass driver as the W500?
The A3HPro is really one of the best bang for your buck CIEM's, if I didn't already have the first version, I would be all over this one.
Finally, the last iem, the M40, just sounds outstanding. Unfortunaltly I spent just a few hours with it, as I ran out of time. My limited impressions were of a fun signature that has you tapping away while listening to music.
Four excellent CIEM's, one a true bargain, one a bassheads dream, one a TOTL charm that competes in the top echelon of earphones, and one an outstanding mid-level performer.
Thanks Barra for giving me the oportunity to listen to these wonderful ciem's.
