For example, this kind of sounds may cause a lot of crispy sound on my wing at max volume. And still there are few up to 80% (max-3). https://youtu.be/a6zSY9m6JD8?si=RmEGzQ8w50_sb1Hd Sounds like headphones oversaturated.

I suspect that your phone is unable to rcognise or power up headphones. I’d recommend to try to upload music files from laptop/computer or if it has to be mobile phone you can try to connect it via powered USB hub (USB hub with powersupply cable and plug).

@Sandra-Cross I don’t have Aqua light, but I swim with Aquas, it doesn’t get in the way at all, once you put them on, there’s little to no sliding, so you won’t even notice them.
