I posted detailed impressions a few days ago on the W60 with the Bluetooth V2 cable vs the older V1 cable.

But I also have some impressions of the W60 in general to add, both wired and wireless, which I added to my V2 review on Amazon. Here is what's missing from the link.
"My son and I got our Westone W60 IEM at Rocky Mountain Audio Fest in Denver CO several years ago. I acquired our Bluetooth V2 cables directly from Westone Labs in early May 2019. My son and I have been using these Bluetooth V2 cables on our W60 since then, for over three months, with no problems in quality. Our three V1 cables are several years old, and none have failed us yet.
For the past few years I have loved my Westone W60, which fit me better than the W80 and offer 95% of the sound, while being easier to drive. The W80, on the other hand, are one of the ultimate in universal fit earphones when paired with a nice amp, such as the CEntrance HiFi-M8, and DACportable, or their BlueDAC. As many already know, in HiFi audio the last 5% in audible gains can double the cost of your setup.
To get the best sound and fit from the W60, one must try a variety of the included ear tips, as they do affect the sound more than you would think. I get better sound isolation and comfort for long listening sessions from the short medium Complys foam tips, at the expense of a slightly darker and less open sound. I get the best sound overall from the medium silicone Star tips, and can still listen for 2-3 hours at a time without needing to take a break to scratch my itchy ear canals due to sweat forming against the silicone.
If you need the best reference quality universal fit IEM, you have a nice quiet amplifier, and cost is not an issue, then I would say to consider the W80, unless you have small ears since the IEM body is a little fatter. The larger W80 are more difficult for me to get sealed in my ears vs the W60 but once I do it's worth it, while my son is unable to fit anything bigger than the W60. And the price point, when you start out with the W60 and no amp, is so much more bang for the buck. And the fact that they can be easily driven by a small Bluetooth V2 cable is a big plus.
In a nutshell, the W60 could be my one and only universal Fit IEM or earphone. They offer true reference quality sound and transparency, with strong bass, vivid midrange, and clear detailed treble."
As for the question above - what current model sounds like a W3 now, I can't say there is one. I don't have the W30, but do have the W40, W50, W60, W80, and ES60 customs (plus older models W1, W2, W3, W4R, and UM3x, as well as the ES3x and ES5). The W40 are a reference type IEM, with good frequency balance but not the same transparency and punch or micro-detail of the W60, but they are close cousins. W50 are the "fun" bassy Westone but they are darker sounding than the W3, so not the same with less noticeable air and micro-detail. The W60 are definitely a reference quality IEM that are also fun and energetic, but true to the source as well.
All of these have a similar sized shell to the W3 and fit my ears well. If you like the W3 you may not like the W40 as being too neutral, and you may enjoy the punch of the W50 but miss the treble presence of the W3. In my opinion the W3 lover will also love the W60, despite also being a "reference" IEM.
