-PST precision tuning technology; divits are used on the surface cone to achieve specific tunning.
Out of speculation, as the name implies (adventure), this might have to be something to be used outdoors probably hiking.
Since they came up with some newer earphones intended for cycling, I'm guessing these are just for outdoor use and wont have any close sound to they're flagships.
DDM had to be worn straight down right? Since the ADV is configured to only go over the ear, I'd think microphonics would be minimal. When I wear any cable over the ear and tuck it under my shirt, I get minimal microphonics doing yard work.
These might be good monsoon-season iems...can't wait to hear what the sound is like, though being arguably marketed as a sort of mainstream product suggests to me that 'bass-heavy' could be in the cards...wait and see time.
Westone has some teaser posts on their Facebook page. One looks like a shot of the new case for the adventure series.
Same with the Klipsch Custom 3 and the cables went over the ear. On the bright side, the cable is replaceable so there are other cable options out there.
