BUILD AND DESIGN
Both headphones are very comfortable to wear. The LCD-2 is larger and heavier, but the weight is well distributed. The Apollo Pro is lighter and smaller, which is always a positive as long as the comfort is there, and it is.
They’re both built with high quality materials. The pads are soft, and they have headbands with a strap. The Apollo Pro uses wood for the cup ring, while the LCD-2 Classic uses some sort of composite material.
Both have detachable ~2 m cables. The Apollo Pro cable uses dual 3.5 millimeter connector plugs and a 4.4 mm termination jack (there are adapters included). The LCD-2 Classic uses the 4-pin mini-XLR connectors typical of Audeze and ZMF and comes with a 6.35 mm termination jack.

Tonight, Tonight by Stephen Wilson jr.
This is an excellent cover of the Smashing Pumpkins classic. The LCD-2C sounds great, with a very balanced, detailed, and laid-back character. It sounds darker than the Apollo Pro, which has a slightly brighter tonality but a similar detail level; though if pressed I’d say the LCD-2C might be a tad more refined sounding here.
In The Mountains by Espen Eriksen Trio
Here too, they’re similar, but the LCD-2C is a tad darker and slightly more refined sounding.
Re-Melt by Tord Gustavsen Trio
They’re very similar. Not identical, but the differences are really small. Both sound good.
Sandermosen by Maridalen
The LCD-2C has a slightly more upfront saxophone timbre; the Apollo Pro is a bit darker. But again, both are good, and they are very close in character.
Spontaneous Compositorius by Thomas Agergard
Again, the saxophone is brighter and crisper with the LCD-2C. The Apollo Pro feels more neutral. The bass is equal and very well balanced; the treble is smooth, detailed, and inoffensive with both.
Teardrop by Massive Attack
Both have excellent quality bass, with tightness and neutrality rather than bloom. The LCD-2C has a tad richer bass presence. The Apollo Pro has more tender and refined vocals.
The Hidden Camera by Photek
Again, they’re similar, but the mids are a bit brighter and more energetic with the LCD-2C. I feel the Apollo Pro again is more neutral and refined. Both have excellent bass, and the percussion doesn’t sound dry on either (as it can do on many headphones).
How Deep by John Scofield
Also here they’re quite similar, but the mid-range, especially the electric guitar, sounds a bit more energetic with the LCD-2C; there’s a slight shimmering quality to the mids. It’s mostly charming, but the Apollo Pro feels more neutral and flatter.
Eye of The Day by Marta del Grandi
The Apollo Pro is excellently balanced; vocals are not overly warm nor recessed, and they are very detailed and nuanced. On the LCD-2C, the vocals are more intimate with a more colored feel.
The Apollo Pro has more powerful bass here, but it still does not feel boosted or overdone.
Midnight City by M83
They’re quite similar tonality-wise. The Apollo Pro feels a tad cleaner and more refined.
Jambi by Tool
The Apollo Pro has more bass; the LCD-2C has more upfront vocals and crisper mids. Again, I think the Apollo sounds more neutral and less colored.
It Could Be Sweet by Portishead
The Apollo Pro has excellent bass with good presence and great quality. Vocals are smooth yet nuanced. The LCD-2C has less bass and crisper vocals.
WRAPPING IT UP
Sound Signature
Both the LCD-2 Classic and the Apollo Pro are quite neutral sounding, with a dark rather than bright tint.
Treble
The treble is smooth and non-intrusive with both. If you’re a treble head, it might not give you your best fix ever, but personally, I prefer this kind of treble presence.
Midrange
The midrange is quite neutral, but more so with the Apollo Pro. The LCD-2 Classic is a bit brighter and more upfront, more “shouty” to put it harshly.
Bass
They both offer high-quality bass. They are both quite neutral, and neither of them has a boosted bass presence. The Apollo Pro offers slightly more sub-bass quantity than the LCD-2 Classic, but it is not a big difference.
Soundstage and Imaging
The soundstage size is pretty similar; imaging does not differ too much, but when there is a difference, I think the Apollo Pro comes out on top.
Detail, Dynamics, and Timbre
I think both deliver nicely in terms of detail, but the Apollo Pro usually comes off as a bit more refined and nuanced.
In terms of dynamics, I find them very comparable.
When it comes to timbre, I find them both to be pretty neutral and mostly sounding very natural with the tracks in my playlist. I like how they sound; the LCD-2 Classic is a tad crisper and a tad “shouty” in the mid-range, but it is just something I think about in direct comparison.
CONCLUSION
Comparing the Apollo Pro and the LCD-2 Classic, I was surprised at how similar the sound was. What was even more surprising was that when there was a difference, it typically was in favor of the Apollo Pro. It comes across as even more neutral, slightly more detailed and refined, without a real downside, except the lack of slight coloration that you get with the LCD-2 Classic.
