These opinions are taken all in relation to my existing W60s. The songs I chose are simply songs I'm used to listening to for consistency's sake. Prices are in Japanese yen. Divide by ~100 to get a rough ballpark for USD. Note that prices in Japan might be different from the US, such as the Audeze ones which are way more expensive in Japan
Audeze iSine 20
75000 Y
Pretty bad insulation. Zero distortion and mud. Good bass. Can rumble.
Very clear mids and highs. More airy feeling. A tiny bit of sparkle.
The knock in Massive Attack - Teardrop is very crisp. Very crisp. So crisp.
Technically perfect, but because of isolation issues it drastically goes down in areas with outside sound. It really needs a quiet environment.
Much wider soundstage than W60. I wouldn't say its an infinite soundstage though.
Requires close to max volume to drive. Because it's so open and the sealing isn't great, things appear a lot more distant like vocals. Had a hard time understanding lyrics like Halsey - Young God.
Audeze iSine 10
Not as much bass as iSine 20. Not as full. Still very technically good.
Shure SE846
Boomier than the W60 with more sparkle. Still solid listening.
Heir Audio IEM 8.0
128,900 Y
Too sparkly. Right at 5.5 KHz.
JH Audio IEM-JH Rosie Siren Series

Not as intimate sounding. Recessed vocals. Just an OK fit.
Not too impressed, especially for the price of $900.
JH Audio Layla II Universal Fit

Everything is clear. Nothing to fault.

Good overall, but female vocals hurt a bit like Alessia Cara.

Female vocals hurt a bit. Good overall.

Doesn't sound as full. Missing something. A bit anemic but still good.

Full sound but a bit muddy in the middle.
Whoa. Alessia Cara's voice sounds different from what I'm used to. Like missing the middle range of her vocals. Fatal flaw.

Excellent. Everything comes through. Great listening experience. Really really like these.
Ultimate Ears UE18+Pro
199,800 Y
Excellent. Halsey - Gasoline has such good vocal clarity, presence, and realism that it took me back. Volume almost 90% to drive. Better than UERR.
Aroma Witch Girl S
90,000 Y
Very sparkly. Very vocal forward.
Unlistenable. And $900.
Westone W80
198,000 Y
I think the demo is broken. Everything feels recessed, too sparkly. UERR so much better. It's gotta be broken.
Westone W30 for Japan Limited
38,680 Y
Heavily shrouded compared to W60. Don't like at all. Nothing is crisp. Bass has something off about it. Wouldn't buy at all.
Klipsch xR8i
35,720
Vocals not clear and SO boomy. SO BAD! Hardly anything cuts through the boominess. Basically listening to mud for $350.
Skullcandy
Dime Mic1
5,000 Y
Even more boomy than the Klipsch. But clearer highs. Boominess is crazy. Overpowers vocals. Missing the mids. Hurts the ears with 5,500 Hz. Turns to absolute mud with the boominess in complex tracks like Alessia Cara - Wild Things. Would be a total waste of money.
AKG N30
25,000 Y
Missing mids. Not much bass. The treble breaks through all the time. Lots of treble, especially 5500 Hz, and no mids and then a bit of bass.
AKG N40SIL
37,000 Y
Adele's voice is shrouded. Completely breaks down in Halsey - Gasoline in complex portion of track at 1:13
Dunu DN-2002
44,820 Y
A bit too much in the high mids. Halsey - Castle gets to be too much in the treble. Vocal clarity is also lost on this track at @1:15. Treble in upper mids is unbalanced. Tires ears out.

Female vocals are missing something. Too much thickness at the bottom range of vocals. Adele isn't as clear sounding in Hello.

Solid all around. Good listening but a bit shrouded compared to W60.
Donguri SYOU

Missing the bass and too much sparkle in female vocals. Hurts.
Sony XBA-N3
37,670 Y
Shrouded. Can create some boom, but full. Fun listening despite the shrouding. Feels powerful in the bass department. Halsey - Castle @1:15 the cymbals get overpowered. U-shaped frequency response.
Sony XBA-N1
21,470 Y
Boomier than the N3. Halsey - Castle @1:15 too much mud. Cymbals not as overpowered, but it's just mud.
Sony MDR-EX1000
42,590
Feels anemic and treble is overpowering in cymbals.
Sony XBA-Z5
62,930 Y
Much more balanced. But a bit shrouded.
JVC HA-FW02

Pretty solid, just shrouded overall.
Shure KSE1500 with amp and DAC included

Crystal clear everywhere. Soundstage is the same as other IEMs. These are just so clear.

Not bad.
Surprisingly clear and somewhat balanced from this price segment. Recessed mids.

Highs are too high.
Dragonfly Black DAC Amp
Noticeable difference on the S5. Vocals are way more crisp and real.
Dragonfly Red DAC Amp
WTF the volume is so low! Unusable and the manufacturer hasn't released an updated in 2017. The black has no problem. *edit* I've since bought the Red and found a fix for the low volume issue (involves root and running shell commands with Tasker to increase the hardware volume level). Prefer it to the Black because it's more detailed.

Very clear and sharp highs. Everything is crisp. The highs back off just enough to not hurt.

Very sparkly. But very clear throughout. The upper mids really knock well.

Too sparkly with DFR
Without DFR it loses a lot of soundstage and clarity. But not bad.
Pioneer SE-MS5T-T with DFR

Very thin and sparkly with DFR. Zero bass. Nothing in the 100-200Hz range to feel.
ATH-WS1100 with DFR

Have to apply EQ to remove sparkle.
Nice bass. Rumbles. A little bit of shroud in the mids. Missing the clarity of the W60s.

Pretty excellent everywhere. Missing some mids, not as crisp there.

Whoa. Recessed vocals. Recessed mids and bass. Don't like it at all. Missing fullness and it sounds not smooth.

Nice wide soundstage and bass that rumbles. Highs too high.
Astell and Kern AK T8iE and DFR
103,370 Y
Warm sound. Solid all around. Very nice bass. Not bright either. Would definitely consider buying. Very fun to listen to. Bass rumbles more than the W60 for sure. I feel like it's what the Shure 846 should have been (no sparkle).
Passing thoughts: why does my DFR make all the over-the-ear cans so sparkly? Possibly because it can't drive the higher impedance and bass?
*** KSE 1500 revisited ***
More KSE 1500 at another store.
All with the DFR and the built-in KSE amp DAC.
Everything is so clear and all sounds are coming from the ether.
There is no crunchy bass like my W60 and Layla II. Vocals are amazing. Halsey - Gasoline at 2:23 doesn't sound great. Missing the bass.
When the vocal is all there is, it's great. Breathtaking. But Lorde - Royals @0:36 "and everybody's like..." it gets really distorted on the KSE1500. And "we'll never be royals..." @0.45 as well. Sounds like a car window left cracked open in the back and there is a muffled buffeting sound. The snapping sound on Royals is more penetrating and crisp on the Layla than the W60, but the vocals are more forward on the W60.
The highs and mid highs are just so so crisp on the KSE1500.
The vocals are simply incredible. The noise floor is zero.
Lacks the warmth and thickness of the W60 and Layla.
Closer - Chainsmokers : the W60 vocals are way more recessed than the KSE1500, but it sounds way fuller. The Layla is not as warm as the W60 without the bass boost adjustment. The Layla is basically so very close to the W60. @1:31 "you look as good as the day..." Vocals On the Layla sounds recessed. Hands clapping / fingers snapping on the KSE1500 is so SO satisfying.
Massive Attack - Teardrop : the knock on the KSE1500 is satisfying. Not as sharp as the Audeze. Wow, gets distorted @0:45. The Layla and W60 don't.
The highs are crisper on the Layla than W60.
Coldplay - Lovers in Japan is still a complete mess on the KSE1500. Just a shitty song.
Owl City - Cave In: @0:15 the bass line sounds really crunchy and distorted on the KSE1500.
Sheppard - Geronimo: "So Say Geronimo..." definitely hear distortion on the KSE1500.
Lords - Team : KSE1500 @2:30 distorts after some amazing mind blowing vocals. Vocals sound like someone talking right next to you into your ear. Vocals sound crunchy after 2:30.
Layla not as warm as W60. The W60 might be a bit too warm.
Shure 846 has crisper highs. But again, a tad too crisp. More elevated mids. Not as much muffling feel.
UM Pro30 Clear
44,710 Y
Definitely a U-shaped frequency response. Gets muffled in the mids compared to the W60s for sure. Low end is too much, like constant muffling. The W60 has a similar muffling feel, but better mids that break through.
Shure SE425
27,940 Y
Wow. Missing so much from Adele's "Hello." SO MUCH. Replaying on W60 you just get taken aback by all the extra detail and immersion. Lacking lots of detail. Just... Bad.
Shure SE535-V-J
48,400 Y
Is better than SE425 but not by much.
UERR
Is like the W60 but without nearly as much muffling and crisper highs. Maybe a tad too crisp.
