Just curious, which Sennheisers did you give up on in favor of APP3?

I have over-the-ear Momentum 3 and love it, but if APP3 provides better sound quality and better ANC I might consider switching as Momentum 3, while I love it, is bulky, heavy, and started to wear off and break down.

Drop x Sennheiser HD 58X Jubilee through a Qudelix 5K. Both are great pieces of kit, the Qudelix especially. The onboard parametric EQ combined with AutoEQ is fantastic. However, after running a hearing test and enabling Hearing Assist, the EQ on the Airpods is incredible and everything sounds very natural. I have no idea how they managed to get this much soundstage and bass out of these things. I also have a pair of Grado SR 80, and have a soft spot for Koss KSC 75.

FWIW I got mine at Costco and their return policy is top notch, and I believe they include AppleCare+ with the purchase. I had bought my APP2 fairly recently before the APP3 were released, experienced buyers remorse, but had kept them in like new condition with the box and accessories, and had no problem exchanging them.

I have an HD450 BT pair and they’re my first ones that have ANC— I’ve found it a game changer for long flights. The only bummer is that wearing cans interferes with a neck brace like trtl; on that basis alone I’d be interested in trying ones that were in-ear style.

What parts are breaking down on yours? The earpads are of course replaceable, and if you had the awful loose yoke problem I’m guessing you wouldn’t be so calm.

Cushions (yeah replacable but not super cheap), the cable that connects one earpiece to other, the bit connecting the earpieces, the hinges around the earpieces.

Literally everything. The sound is still great and battery is awesome. But I doubt it will last long.

(Just to be clear: I've used it A LOT over the years, and is already worth every penny I spent on it)

Huh. For what it’s worth, the Chinese lambskin (not generic “leather”!) pads that you can get for ~$15 from Aliexpress, Geekria, etc. work as well as the official ones in my experience. (For other headphones, you can’t always get generic replacement pads made of the same materials.) The only difference I’ve been able to discern is the L/R labels are printed using a different technique.

Let me have a look. Do you think the material is of good quality and healthy (no weird questionable materials for wearing/skin contact for long time with sweat etc)?

I’ve spent a few weeks with mine and, as best as I can tell, they’re indistinguishable from the original ones, except the dye of the L/R markings is on top of the cloth rather than inside it. These ones (black lambskin, currently 14 USD): https://www.aliexpress.com/item/1005005961714330.html.
