Costco HIS tend to like to boast that the Philips aids are rebranded Oticon aids. It’s not true. While they share many peripheral technologies and accessories that make it seem like they’re a rebrand, they’re not, because their core technologies are different. Bernafon is another William Demant subsidiary that shares a lot of the peripheral technologies and accessories with Oticon, but again their core techs are different.
If you’re not in a hurry, I would suggest that you wait until Costco starts carrying the upgraded Philips 9050 before trying it out. It carries the new 4D sensor technology that the Intent does, and its core technology, the AI Noise Reduction functionality, has also been improved.
Maybe someone who already owns the Philips 9040 will comment on whether Costco sells a disposable battery version of it or not. I know the Real has a disposable battery version.
