I don't know about that. But you could run the cannula from the back of your head, over your ears to your nose. [Maybe] Think I have seen with Lisa they do it and use an elastic strap to hold it in place behind the head.
To be thinking out of the box as another idea; could you incorporate or somehow add your jewelry to/with the cannula? Just saying because you're not the only woman that wears jewelry and uses oxygen. That is a whole untapped list of clientele.

Sorry I have duallies

Thanks @A MyCOPDTeam Member just yesterday I tried it backward with a clip to the back to my shirt, and it is pretty good. I'm actually wondering where I think I'm going, to add a necklace with what I'm wearing.

@A MyCOPDTeam Member there are some clips that can attach to your glasses and run the tubing up to your glasses and possibly down the back if that's better. Check on Amazon and you can order and try the oxybreather or clips and just return them if they don't work out. I just want to wear my damn jewelry around my neck it isn't rocket science 🙃

Ali e Rose, thx for answers about clip. I would like to try the oxybreather but wear glasses & hearing aids so wonder if earpiece could handle all that. I am on ox 24/7 but am pretty active, using personal concentrator to go out.
