How to choose the right domes
Match the size
Domes are sized in millimetres (typically 6–12 mm). Use the same size your audiologist fitted — too small whistles, too large feels tight.
Match the style
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.
Replace every 2–3 months
Swap domes when they discolour, stiffen or tear. Fresh domes keep sound clean and prevent earwax reaching the receiver.
Getting the most from your batteries
Match the size & colour
Hearing-aid batteries are colour-coded by size: 10 (yellow), 312 (brown), 13 (orange) and 675 (blue). Use the size your device takes.
Wait 60 seconds after the tab
These are zinc-air batteries. Peel the tab, then leave it off for a full minute before inserting — it lets air activate the cell and adds days of life.
Store cool and dry
Keep batteries at room temperature with the tab on. Avoid the fridge and loose pockets, where coins can short them.
Not sure which dome size you need?
The Dome Finder walks you through it by brand and model.

What domes does the Starkey Evolv AI use?
The Starkey Evolv AI uses Comfort domes. Match the size (in millimetres) and style your audiologist fitted — it's usually printed on your current dome. Not sure which to pick? Send us a photo and we'll match it.
How often should I replace the domes on the Starkey Evolv AI?
