MiniFit domes that fit the Oticon Opn.
Wax guards that protect the receiver on your Oticon Opn.
Domes are sized in millimetres (typically 6–12 mm). Use the same size your audiologist fitted — too small whistles, too large feels tight.
Open domes keep the ear canal ventilated, generally for mild to moderate loss; closed and power domes seal more sound in, generally for moderate loss or worse. Tulip and double-vent styles sit in between.
Swap domes when they discolour, stiffen or tear. Fresh domes keep sound clean and prevent earwax reaching the receiver.
Replace a wax guard as soon as sound becomes weak, muffled or cuts out — that usually means the filter is clogged, not the hearing aid failing.
Use the removal tool to pull the old filter, then press in a new one. Never reuse a guard — it's the cheapest part protecting the most expensive one.
Filters are the most common reason a hearing aid goes quiet. A spare pack in your kit means a 30-second fix instead of a clinic visit.
Also compatible with this platform — not stocked at HearingTracker yet.
The Oticon Opn uses MiniFit domes. Pick the same size (in millimetres) and style — open, closed, tulip or power — that your audiologist originally fitted. Not sure? Send us a photo of your current dome and we'll match it.
Yes — every part on this page is matched to the MiniFit platform the Oticon Opn uses. If you'd like us to double-check before you order, just get in touch with your device details.
Replace domes every 2–3 months (sooner if they discolour or harden), and wax filters every 4–8 weeks or whenever the sound becomes weak or muffled.
