I know it has been months, sorry about that. I would say that, from first principles, you begin by asking what are Westone iems? Plastic encased iems, with thin plastic stems, and packed with generic, BA drivers from Knowles. Are they “tuned for specifically Westone”? Sure, yes, but the larger players can ask that. They do fit into a small shells, and sure the plastic is comfortable, and the sound is nicely tuned. For UMPro50s are legit good iems. Provided the stems don’t come off. The Mangrid Tea and the Moon KXXXs here are better, they have better tech, better made,
based around research & user feedback from the last decade… these are each good things. The Triton is a better sounding iem, (at 1/3 of the price) than even the UMPro50, it is a trade-off, the latter is a bit faster, cleaner, and sharper
sub-bass from memory, but doesn’t have the fullness and depth or
fankly scale of the bass of the former. And they don’t break as easily - important for an iem, because iems are small (which is convenient), but correspondingly delicate. I personally enjoy the slightly rolled off signature of their so-called “consumer” W items also. The W60 is a good sound, I dislike sibilence, which put me off the drivers that first appeared for a high end iem
in that first $999 silver Campfire that
made waves. They did it really
well first, as really BAs were the only driver convig in town for quite a while. Now there are so many Berillium drivere good, and now packed with BAs also in many, now it is just a case of take your pick.
