I’ve spent a lot of money in diffusers, including do!aqua, jbl, ada, neo co2, co2 art, in-line...and yes they all make some noise except for the co2 art bazooka and the inline ones which are inside the stand anyway.No i didn't get the bendy version as i knew i would screw it up, instead i bought a little glass u-bend which i've already broken too
I've only ever used the neo diffusers, they've always hissed for me, i thought that was normal?
The new neo co2 isn’t the loudest but as I asked some guys on YouTube that are using it, they said that it was silent, so I didn’t expect the hissing noise on this one. Got the old version and I’ve to say it’s an bit louder.
I got the glass U bend to with the bazooka , glass is sexy but fragile, doesn’t it?
