Bathys do not have passive mode. They are full-time, 100% ANC. I think the lights on the side must cost a few hundred dollars as the Bathys are not worth a penny over $400. I tried dozens of cans and I got my favs, ML5909. My runner up was the B&W PX8. I did not keep them as my Momentum 3 are basically the same level of sound and cool style quality. Still love my ATH M50XBT (with Brainwavy angled pads). The closest sound to the 5909 are my Drop Panda. Love your videos. Thanks.
What I mean, is the headphones switched OFF and you have the headphones on your head. Not listening to music or any sourced sound. Only the ear cup isolation nothing else, just to get some sleep on the airline. Even the 1MORE Sonoflow (slightly) also even has better ear cup isolation!
I have never bought or reviewed any headphones that are just bluetooth. All my bluetooth headphones have ANC so unfortunately I can't recommend Hopefully somebody else can
