As promised, here's my first impressions:
I'm running a Surfans F20 with 320Kbps Mp3s. With my previous earbuds, the Shure SE215s, I had the EQ dialed in to reduce the mid-lows, keep the sub-bass the same, keep the mids the same, and increase the upper mids and treble. With the Westone W80s, I've deactivated the EQ for the impressions below.
The first song I listened to was by the band Keldian, their song Lords of Polaris, the dynamically enhanced version they released on Bandcamp a while back. For the totality of my impressions given below, I listened to a range of power metal, power-death, progressive power metal, symphonic power metal and power metal with folk elements. (A cookie to anyone who can guess my favorite genre. Heh heh.)
They immediately blow my SE215s clear off the continent. The sound is fuller, bigger, lusher, more realistic. Immediately examples I notice are that in songs with, for instance, cellos or thick woodwind sounds, I'm impressed by them with effortlessness from the W80s. Whereas with the SE215s certain instruments were an indication of sound, the W80s actually deliver the sound itself, no hints, just facts.
Another example is in piano: When a piano key is hit, if it's a real instrument, the key has a kind of clunky sound as the key strikes the piano's frame, a kind of knocking. This is revealed in totality with these earbuds. Again, you could technically hear it on the SE215s, but you didn't experience it for yourself: you were just being given the information, advised of the sound's existence. With the W80s, you are there experiencing it first-hand.
Sub-bass is far, far more. . . well,
relevant. There's pretty much no strong sub-bass presence in the SE215s, not in the full, powerful buzz that the W80s present. One other thing I found interesting is that I hooked it up to my Nintendo 3DS for a couple rounds of Tekken 3D, and
boy was it intense! It was like wearing a high-end gaming headset when playing a full console game. I look forward to playing more games on my 3DS now, ha ha!
I'm not going to give a general lows-mids-highs breakdown now because I haven't spent enough time with them, but one other thing I'm noticing is that they're more dynamic, or perhaps I should say they're more revealing of dynamics. When things get quieter and louder, these volume changes seem more pronounced and evident with these than with the Shure SE215s.
I wish I had a higher end IEM to compare these with. I paid a paltry $130 for the Shure SE215s on July 23rd, 2017 (that recently?) and they have been stalwarts ever since, but at $130 bucks, they weren't ever trying to be high-end, but only "excellent for the price," which they are. If the Westone W80s weren't head and shoulders above them, then Westone would retire in shame, given the massive price difference.
I'm listening to these buds as I write this, and anticipate listening for a good while longer, since I just charged the battery.
At the moment, if anyone wants to listen along, I'm listening to the band Asylum Pyre's song Love Ecstasy. Great stuff, requiring equipment capable of reproducing operatic and non-operatic female and male vocals, classic instruments like piano, and of course the heavy metal kit of a metal band, electric guitars and drums. These earbuds seem to be doing so, hitherto, with aplomb.
