Oticon Jet PX BTE series – Accessories & Compatibility Guide | Japebo
Looking for the right Oticon accessories for the Jet PX BTE series? This guide helps you identify what fits, what to look for when replacing wear parts, and how to avoid ordering the wrong item. BTE (Behind-The-Ear) models can use different tubes, earhooks, earmould connections and ear-piece styles, so a quick compatibility check before you buy saves time and frustration.
What “Jet PX BTE” means for accessory compatibility
The Oticon Jet PX BTE series is a behind-the-ear hearing aid family. With BTE hearing aids, sound travels from the device to your ear through either:
A thin tube ending in a small ear-piece (often called a thin-tube or miniFit tube style), or
A standard tube + earmould connection (typically using an earhook and conventional tubing).
Because both setups exist, the most important step is to identify how your Jet PX BTE is fitted today (thin tube vs earmould). If you match that, the rest of your accessory choices become straightforward.
Common accessories used with the Oticon Jet PX BTE series
Below are the accessory types most frequently replaced on Oticon Jet PX BTE fittings. Availability can depend on your exact BTE variant and your receiver/tube setup.
Tubes and earhooks (BTE fittings)
If your Jet PX BTE uses an earmould, you typically need:
Earhook (the plastic hook on the hearing aid that the tube attaches to)
Standard tubing (connects earhook to earmould)
If your Jet PX BTE uses a thin-tube style, you typically need the correct thin tube length and side (left/right), plus the matching end-piece that sits in the ear.
Domes / ear-grips (thin-tube setups)
For open fittings, users often wear a small silicone dome on the end of the tube. Dome selection affects comfort, retention and sound:
Open domes: more ventilation and a more “open” feel
Closed / power domes: more seal, often more bass and less feedback (but less ventilation)
If your ear-piece tends to slip out, you may also use a small retention/ear grip (depending on the tube system).
Wax protection (important for sound quality)
Wax protection parts vary by ear-piece system. Some thin-tube ear-pieces use a replaceable wax guard, while earmoulds may rely on regular cleaning and tubing changes. If your sound becomes weak or muffled, wax blockage is one of the most common causes.
Hearing aid batteries (if your model uses disposable batteries)
Many BTE hearing aids use standard zinc-air sizes (commonly size 13 or 312, depending on model). Check the battery door or your current battery packaging to confirm the correct size before ordering.
How to choose the correct Oticon Jet PX BTE accessory
Use this quick checklist to choose accurately:
Identify your fitting type: thin tube with dome, or earmould with standard tubing.
Check left/right: tubes and some ear-pieces are side-specific.
Confirm size/length: thin tubes come in lengths; domes come in diameters.
Match what you already wear: if you like the comfort and sound, reorder the same style and size.
If you’re unsure: compare your current part visually (shape, connection type), or use your hearing care professional’s fit information.
Tip: If you recently changed your fitting (e.g., from open to more closed domes), be prepared that sound and comfort can change. If possible, follow the fitting recommendation you received with the hearing aid.
Common problems (and what replacement parts usually fix them)
Sound is weak, intermittent or muffled
Check for wax blockage in the ear-piece and replace wax protection if applicable
Inspect tubing for moisture, cracks or hardening (replace if stiff/yellowed)
Make sure the dome is securely attached and not torn
Whistling / feedback
Try a better-sealing dome (closed/power) if appropriate
Check that the dome size is correct and inserted properly
Ensure earmould tubing is seated tightly on the earhook and mould
Comfort issues or the ear-piece won’t stay in
Adjust dome size/type
Consider a retention/ear grip if compatible with your tube system
If you use an earmould, check whether tubing length needs adjustment (too long/short can pull)

FAQ – Oticon Jet PX BTE series accessories
Are all Oticon BTE accessories compatible with the Jet PX BTE series?
No. Compatibility depends on the specific connection system (thin tube vs standard tube/earhook) and the ear-piece style. Always match the accessory to your current fitting system.
How do I know if I have a thin tube or an earmould?
A thin-tube setup uses a slim transparent tube ending in a small dome. An earmould setup uses a custom mould in the ear and usually thicker tubing connected to an earhook.
How often should I replace tubing or domes?
It depends on wear, earwax and moisture. Domes are typically replaced regularly for hygiene and fit; tubing is replaced when it becomes stiff, discolored, cracked or causes sound issues.
What if I don’t know my dome size?
The safest option is to check the size printed on your packaging (if available) or compare your current domes to the replacement sizes. If you’re between sizes, comfort and seal will determine the best choice.
My hearing aid uses batteries—how do I pick the right size?
Check the number on your current battery pack (e.g., 13 or 312) or look in the battery door area for the indicated size. Order that exact size.
