Nothing stands out in particular here, it's just a well-recorded album.

You're right, sorry.

For whatever reason, I (almost) routinely click the "Ultra HD" button on each track when I'm listening to an album, and they are uniformly 24/96 or 24/48, etc. That hasn't always been the case, but I've observed it enough to be satisfied that it's standard now. In the case of older albums, it's...

If every track on an album is labeled "Ultra HD", they all have the same bit/sample rate. That's been my experience, anyway.

Nice. I'm considering this for a backup. I might get a few USB C cables to get the price up, since they don't last very long for me, for some reason.

Sennheiser HD 560s $149.99 at Best Buy. https://www.bestbuy.com/site/sennheiser-hd-560s-wired-open-aire-over-the-ear-audiophile-headphones-black/6433188.p?skuId=6433188

I bought my replacement pads from this Amazon & Ebay seller. On Ebay, it shows the hd 560s pads as OOS, but on Amazon, they list the pads for the HD 400s, which should be identical. To be on the safe side, I'd try to communicate with the seller to make sure they're the same...

They may soften a little, but they can't wear out in two week's time. I'm on my second pair of earpads, and I didn't experience the same pinching feeling I did when the headphone were brand new.

Ok, I see now. Mine pressed a little hard for the first 2 weeks or so, then they got more comfortable.

What do you mean by stretchable? It's adjustable.

The cable on mine broke right where it goes into the earcup.

The 1350 and T51P were introduced to compete with the Sennheiser HD 25, which is still in production. I never heard it, so I don't know if it's a good alternative.
