Rexton BiCore BTE series – Accessories & Compatibility Guide | Japebo
If you’re looking for Rexton BiCore BTE series accessories, you’re in the right place. This guide helps you understand which parts fit Rexton BiCore BTE hearing aids, how to choose the correct variant, and what to do if you’re unsure before you order.
What does “BTE” mean in the Rexton BiCore series?
BTE stands for Behind-The-Ear. Rexton BiCore BTE models sit behind the ear and send sound into the ear via either:
An earmold + tube (classic BTE setup), or
A thin tube + dome (often called slim-tube fitting), depending on your configuration.
This matters because many accessories (especially tubing, domes, and earmold parts) are fit-dependent. The same hearing aid family can use different consumables based on how it is set up for your ear.
How compatibility works for Rexton BiCore BTE accessories
Accessories and consumables for the Rexton BiCore BTE series usually depend on a few practical details:
Your exact BiCore BTE model (model name/number can affect which parts fit)
Your sound outlet setup (earmold & tube vs. thin tube & dome)
Connector type and size (especially for tubes and domes)
Battery type (if your device uses disposable batteries rather than rechargeable power)
If you’re replacing an existing part, the safest approach is to match what you already use (same shape, same connection, and ideally the same product code).
Common accessory types for the Rexton BiCore BTE series
Depending on your fitting, you may need one or more of the following:
Domes (if you use a thin tube)
Domes are the soft tips that sit in your ear canal. They come in different styles (for example open vs. more closed variants) and sizes. The correct dome affects:
Comfort
Sound balance (bass/feedback control)
Retention (how securely it stays in place)
Tubing / thin tubes
BTE fittings may use standard tubing (with an earmold) or a slim/thin tube (with a dome). Tubes are wear parts—over time they can harden, discolor, or loosen at the connection points, which can reduce sound quality or cause intermittent sound.
Earmold parts (if you use an earmold)
If your Rexton BiCore BTE is fitted with an earmold, you’ll typically replace tubing and occasionally other earmold-related parts depending on the mold type. A good seal and stable tube connection are key for consistent amplification.
Wax protection and cleaning items
Even with BTE devices, wax and moisture can block the sound outlet (especially at the end of the tube/dome). Regular maintenance items can help prevent:
Reduced volume
Distortion
Intermittent audio
Batteries (for non-rechargeable BiCore BTE models)
If your model uses disposable batteries, the correct battery size is essential. If you’re unsure, check the labeling inside the battery door or your original battery packaging.
How to choose the right Rexton BiCore BTE accessory
Use the steps below to avoid ordering the wrong part:
Identify your setup: Do you have an earmold with thicker tubing, or a thin tube with a dome?
Match the connection: Compare the end that attaches to the hearing aid and the end that sits in/near the ear.
Match size and style: For domes, choose the same size and type you already wear (or the size recommended by your hearing care professional).
Check any markings/packaging: Product names and codes are the most reliable compatibility indicator.
If you don’t have the old packaging, you can often still identify the correct option by comparing the shape and connection to your current part.
Common problems (and what accessory usually fixes them)
The sound is weak or muffled
This is often caused by blockage at the end of the tube/dome or general wear. Replacing the dome and/or tube and cleaning the sound outlet can typically restore normal sound.
Whistling / feedback
Feedback can happen when the fit is too loose or the dome/earmold seal is not right. Switching to a better-fitting dome size or replacing worn tubing can help.
The tube keeps slipping off or feels loose
Tubing can stretch or harden over time. Replacing the tube (and ensuring the correct connector type) is usually the solution.
Discomfort or the dome falls out
Try a different dome size or style (only within the options compatible with your thin tube). Comfort and retention are strongly linked to correct sizing.

FAQ – Rexton BiCore BTE series compatibility
Are all Rexton BiCore BTE accessories interchangeable?
No. Compatibility depends on your exact BTE fitting (earmold vs. thin tube) and the specific connector/type used. Always match the part to your current setup.
How often should I replace domes or tubes?
It depends on wear, earwax, and daily use. Replace them when you notice reduced sound, discoloration, stiffness, poor fit, or hygiene concerns.
How do I know if I use an earmold or a dome?
A dome is a soft silicone tip at the end of a thin tube. An earmold is a custom-shaped piece that fills more of the outer ear and connects to thicker tubing.
What if I order the wrong accessory?
If you’re unsure before ordering, compare connection type and size to your current part. If you’ve already received the item, keep packaging and contact customer service with your model information and photos for the quickest resolution.
