I feel the need to pop my head up and shout out some praise to the W80. I've given Westone a "Proper Bollocking" as the English like to say, regarding the W60 faceplates. However, the W80 does appear to have (finally) corrected the issue. I find the W80 has been a substantial upgrade for the (otherwise) superb W60.
I'm not sure that I would pay full retail for them, but for me, the second-hand for $700, represents an attractive investment.
I prefer these to the K10s and Heir 8.0s that I've previously owned, as well as every other iem I've ever owned.
This isn't surprising to me, as I adore Westone's relaxed house sound (warm, fatigue-free signature) that tends to be found in their W range. I don't feel that the W80 departs far from the formula that works so well for them. It may sound crazy to some, but I honestly preferred the W60s to the Kaizer 10s for everyday use.
Of course, the W80 reaches higher, has a broader soundscape, and is more resolving than the W60, but then it brings two more drivers into play.
My listening has been limited to their EPIC cable, as unfortunately mine was purchased with the ALO separated from the sale. I do have a nice pure silver litz cable on order, so I'm looking forward to checking out any differences.
My set-up is (hear the audiophile groan...) the iPhone 8+. I also listen to (double-groan!!) mp3s using Apples' lossless file code. So I may be missing a lot, but I'm enjoying these A LOT. Also, their comfort remains first in class (even if at the likely cost of some longevity). These are keepers... but I do often say this right before some other shiny thing comes along!
