Signia Motion 13 Nx BTE accessories & compatibility guide | Japebo
If you use a Signia Motion 13 Nx BTE hearing aid, choosing the correct accessories and spare parts is mainly about compatibility: the right style of earpiece (tube + dome, or custom earmould), the correct cleaning and protection parts (wax protection where relevant), and practical day-to-day essentials like batteries and care products. This guide helps you confirm you’re on the right page and choose parts that fit your Signia Motion 13 Nx BTE confidently.
What the Signia Motion 13 Nx BTE is (and why it matters for accessories)
The Signia Motion 13 Nx is a BTE (Behind-The-Ear) hearing aid. Most BTE setups use either:
Thin tube + dome (a small silicone tip in the ear canal), or
Custom earmould (a made-to-measure ear piece), typically connected via a tube.
That physical setup determines which consumables you need most often (for example, tubes and domes) and which parts are not relevant (for example, many classic BTE tube fittings do not use the same receiver parts as RIC devices).
Most commonly needed accessories for Signia Motion 13 Nx BTE
Below are the accessory types people most often replace or restock for a Signia Motion 13 Nx BTE. Exactly what you need depends on whether your fitting is a thin-tube/dome setup or an earmould setup.
Domes (if you use a thin tube)
Domes are the soft silicone tips that sit in the ear canal. They come in different shapes and sizes (for comfort, retention, and acoustic openness). If your Motion 13 Nx is fitted with a thin tube and dome, this is typically the most frequently replaced item.
How to choose: match both the dome family/connection type used by your tube and the that feels secure without pressure. If your current domes fit well, choosing the same type and size is usually safest.
Tubes (thin tubes or tube for earmould)
The tube is the physical sound pathway from the hearing aid to the ear (either a thin tube ending in a dome, or a thicker tube connected to an earmould). Tubes can harden, discolor, or become less secure over time.
How to choose: confirm whether you use a thin tube fitting (often size/length specific left vs right) or a standard earmould tube that is cut to length. If you’re unsure, compare your current tube to product images and specifications before purchasing.
Wax protection & cleaning (setup-dependent)
Wax protection varies a lot by fitting. Some BTE tube fittings mainly need regular cleaning of the dome and tube, while other configurations may include specific wax guards at the earpiece end.
How to choose: check what is currently used on your earpiece. If you can remove a small wax insert (often with a little tool), you likely need a specific wax filter type. If not, your maintenance may be primarily cleaning and replacing domes/tubes.
Batteries (size 13)
The “13” in Motion 13 indicates it uses size 13 batteries. If your device takes disposable batteries (rather than a rechargeable retrofit/variant), keeping a fresh supply is essential for stable performance.
Tip: if you experience shorter battery life than normal, also check for moisture, blocked domes/tubes, or partially opened battery doors.
Care & maintenance essentials
Even with the correct parts, everyday care reduces dropouts, weak sound, and irritation. Useful items typically include:
Cleaning wipes for the hearing aid shell
Drying solutions (especially if you perspire or live in a humid climate)
Small cleaning tools for domes and tube openings
Compatibility checklist (avoid ordering the wrong parts)
Use this quick checklist before you buy accessories for a Signia Motion 13 Nx BTE:
Confirm the device style: Motion 13 Nx BTE (not RIC, not ITE).
Identify your ear-side components: thin tube + dome or custom earmould + tube.
Match the connection type: domes must match the tube/earpiece system you have.
Match left/right where relevant: some tubes are ear-specific and length-specific.
Reorder what already works: if comfort and sound are good, replacing like-for-like is usually best.
Common issues—and what accessory replacement can fix
Sound is weak or muffled
Most often caused by a blocked dome, tube, or wax protection at the earpiece end. Try replacing the dome and inspecting/refreshing the tube. If your fitting uses wax guards, replace the wax filter.
Whistling / feedback
Often linked to a poor seal or a dome that’s too small or worn. A fresh dome or a different dome style/size may help. Also ensure the tube is seated correctly and not cracked or loose.
Dome won’t stay in place / discomfort
Try a different size or style of dome (for example, a more secure/closed option) and check that the tube length is correct. Discomfort can also come from stiffened old domes—replacement often solves it.

FAQ: Signia Motion 13 Nx BTE accessories
Does Signia Motion 13 Nx BTE use size 13 batteries?
Yes. Signia Motion 13 Nx BTE models use size 13 disposable batteries.
Which domes fit Signia Motion 13 Nx BTE?
It depends on the earpiece/tube system your hearing aid is fitted with. Domes must match the connection type used by your tube, and then you choose the size/style that matches your current fit or your audiologist’s recommendation.
Do I need receivers for Signia Motion 13 Nx BTE?
Most classic BTE thin-tube fittings do not use the same detachable receivers as RIC devices. Your Motion 13 Nx BTE typically uses a tube (thin tube or earmould tube) as the main replaceable sound path component. If you’re unsure about your exact configuration, compare your current setup before ordering.
How often should I replace domes and tubes?
Many users replace domes regularly for hygiene and comfort, and replace tubes when they become stiff, discolored, or loose. The ideal interval depends on wear, earwax, and moisture exposure.
How can I make sure I order the right parts?
Check your current accessories (dome shape/size, tube type/length, any wax protection) and reorder the same specifications. If anything is unclear, use product images/specs to match connection types before purchasing.
