I use Pacific ears in Australia. But ultimately it’s going to be the exact same product. Just moulded silicone. So what ever is cheapest. But if you want filters they might be more brand specific, but I don’t really know. In Australia there aren’t many options as far as I could find.
They are moulded to my ears. If you got unusual ears i donno what to say, but I suspect they could custom mould for you too. Go ask an audiologist.
