Headphones should keep working even if the manufacturer goes bust and stops providing software support. And even if your battery dies and spare parts are unavailable. That is precisely the reason why we also sell a cable with a 3.5mm jack for these cans. That way, this product is long-lasting and sustainable even in the (hopefully hypothetical) case that we are not able to support them anymore.
That is the best out of both worlds: you get wireless connectivity and ANC now. And you will be able to use them for as long as you would with wired ones.
