Fairbuds xl spare parts 2023 vs 2025: specifications, compatibility, and colour

I’m trying to figure out what (if any) the differences are between spare parts from the 2023 and 2025 line of fairbuds XL.

I know the speakers are upgraded for the 2025 version, and the headband cover and ear cushions of the 2023 model were PU/vegan “leather” whilst the 2025 model used net fabric (although the PU/vegan “leather” version of the ear cushions also comes in the forest green option alongside regular green and black), but many of the other parts seem to have a 2023 version (which has “(2023)” behind the name of the part) and an (implied) 2025 version (which doesn’t mention a year), but there are very little specifications to really tell if there’s much of a difference between the versions of all those other parts besides the colours. Are there any differences between the versions of the spare parts besides colour? If so, are all parts compatible in any direction/combination or are there limits to that? If colour is the only difference, I don’t really get why they’re listed as separate parts rather than colour variations of the same part.
Also is there a difference in colour between the “black” of 2023 and the “horizon black” of 2025? The greens are clearly different from the pictures, but for the blacks it is much harder to tell if there is a colour difference, so if anyone has seen them both irl and could tell me if there’s a difference, I’d love to know

Fairphone’s repair instructions recommend different screwdrivers for 2025 (Phillips #0) and 2023 (Phillips #00) parts headband, headband base and speakers.

Having said that, I was still able to freely mix the parts of a 2025 horizon black and a 2023 forest green pair of Fairbuds XL

EN in 2nd half – Eine etwa 16 Sekunden lange Animation beginnt mit dem Bild eines schwarzen Kopfhörers, der auf einer Holztischplatte liegt. Beginnend mit dem rechten Lautsprecher werden Bild für Bild und entgegen des Uhrzeigersinns alle schwarzen Einzelteile des Kopfhörers durch grüne ersetzt, bis der gesamte Kopfhörer grün ist, allerdings mit einem orangen Verbindungskabel der beiden Lautsprecher. Kurz blinkt dann links ein kleines oranges Teil unterhalb des Kopfpolsters auf, bevor der gesamte Kopfhörer von links nach rechts wieder schwarz wird. ENGLISH: An animation lasting approximately 16 seconds starts on the picture of black headphones lying on a wooden desktop. Starting with the right speaker, the individual black parts are replaced by green ones picture by picture and counter-clockwise until the whole headphones are green, however with an orange cable connecting the speakers. On the left, right below the headband cover, a small orange part briefly flashes before the whole headphones turn back to black from the left to the right.

(The orange and the black parts that briefly flash up after the complete conversion to the green 2023 XL were 3-D printed parts.)
