I liked it a lot, more than Tidal (what I have now). But the last few months with Qobuz I had streaming issues, because of something on their end. It was a freak issue though. The catalgue was absolutely wonderful especially if you’re into jazz like me. It allowed you to browse record labels too, which I sorely miss.
I switched because of the streaming issues and because tidal has a connect option, which allows me to send music without compression over wifi to my stereo, natively from tidal (spotify has it too, but lower quality sound)
Filters like britta make your coffee or tea taste nicer and you barely have to decalcify your machine or kettle.
But healthier? Never seen any study that proves it (it would be nearly impossible to really make any claim stick, because tap water varies quite a lot across regions and countries)
