I really enjoy my Sennheiser CX Plus in-ears.

I bought the Jabra Active 4 a couple of years ago and can highly recommend them. They sound great, they’re robust, they stay in your ear well during exercise. I think I read on this group recently that Jabra has decided to stop making TWS headphones, so it’s a good (last) time to buy them.

I had the JBLs for 2 rounds and they shit the bed way too early. Switched to Bose QC+ for about the same price and the quality and sound are much better. They don’t last quite as long, (~5 hrs to nearly 8) but it’s a very small price to pay.

Edit: replied before seeing that you said European.

Someone else suggested this brand, I never heard about it before, but I am seriously considering buying one of these. I like the idea of being modular and easy to repair, also, the reviews on the internet say it has a premium quality sound:

Have you looked at fairbuds? https://shop.fairphone.com/de/fairbuds

I think fairbuds can be a great option. They are the earbud from Fairphone a Dutch company. I. Addition to be European they are repairable which is great for these kind of device : https://shop.fairphone.com/fairbuds
