Could you show me a picture of h9 3rd inside the case? Almost decided to buy it…
Sorry mate for the delay, hadn't seen your reply.
Here some images:

A few considerations, after some testing: I suggest not to buy the B&O HX case if that's for the H9 3rd Gen or any other B&O headphones previous to the HX.
The H9 3rd Gen are slightly thicker than the HX, especially in the headband, as you can see in the comparison images. This causes the case to be very tight with them in.
In the closed case image (not closed with the zip), the first one is with the HX inside, the second one is with the H9 3rd Gen inside. You can see the difference.
You can still close it with the zip even if it has the H9 3rd Gen inside, however I wouldn't recommend it as in the long run it could damage the zip of the case or risk damaging the headphones.
The good news is that on Amazon there's literally billions of cases made for the H7/9, so you'll easily find a fit for purpose replacement - even though it won't have "BANG & OLUFSEN" printed on.
I'm hoping you guys are around. I've always like on ear headphones for working out. I jog with a pair of wired Koss Porta Pros that I really love. I consider that my baseline for sound. It can't get any worse. I have a pair of Audeze LCD-4s for home listening that are excellent.
I've found I love wearing bluetooth on ear for working out (lifting weights). I currently have a pair of Koss Porta Pro bluetooth which are really quirky. Ready for an upgrade. Crazy how headphone manufacturers aren't making on ear.
I ordered a pair of Adidas RPT-02. I know. Adidas? At first, they sounded a bit muddy. Worse than the Koss, so they were going to go back. I kept them playing awhile and they are clearing up and just edge out the Porta Pros. So I think I'm done.
But, found a pair of used Bang & Olfusen H8i's in very good shape (build date Nov 2018). Everything I read says the sound is really great for a small on ear.
Should I return the Adidas and go for the H8i's? I just hope they are snug enough to stay in place. Just light / moderate weightlifting.
Are you happy with the Adidas? If so, I'd stick with them. They're designed for use in the gym, they'll get worn out in a way that's less evident than the H8i, and their battery lasts forever if you get the solar powered ones.
Not to mention that they have washable (and hence, replaceable) ear cushions and headband.
H8i may sound a bit better and definitely look much better (they're also slightly lighter), but they'll make your ears sweaty as the ear cups in leather aren't as breathable as the sponge ones from Adidas.
Also, you'll need to buy in advance a few pairs of replacement ear cushions because B&O may run out of stock very soon and once they do you won't have anywhere to buy them (and they ain't cheap
https://www.bang-olufsen.com/en/int/accessories/beoplay-h8i-cushions ), especially if you get the pink or natural colour variants, as their leather wears down extremely easily, see my H9 3rd Gen after a bit more than just a year (of extremely delicate use):

Also, H8i have a on-head sensor that's known to be very easy to accidentally trigger, which I can imagine would bother you especially during workouts. You can disable the sensor if you wish though.
Last thing: even though the Adidas have longer battery life, just be aware that the battery of H8i can be easily replaced (even if you have to unscrew the ear cup that holds it), and can be found easily for cheap money (AHB723938, same part shared with all of their "non-easily-swappable-battery" headphones except H4 that have a smaller one, so same as the newer HX, Portal and H95).
I personally haven't listened to the H8i so can't comment on their sound quality.
Happy choice!
