Oticon Dynamo BTE UP hearing aid accessories & compatibility guide
If you’re looking for Oticon Dynamo BTE UP accessories, the most important question is compatibility: which parts fit your exact Dynamo BTE UP setup, and which won’t. This guide explains the key accessory types used with Oticon Dynamo BTE UP behind-the-ear hearing aids (especially high-power fittings), how to identify what you currently have, and how to choose the right replacement so you can order confidently.
What kind of hearing aid is Oticon Dynamo BTE UP?
Oticon Dynamo BTE UP is a power/ultra-power BTE hearing aid. Most Dynamo BTE UP fittings use either:
An earmould (custom mould in an earhook + tube setup), or
A power dome (in some fittings), depending on your acoustic needs and local configuration.
Because power BTE fittings often rely on a secure, low-leakage fit, many users will have an earmould + tubing rather than open-fit parts.
Accessory compatibility: what matters for Oticon Dynamo BTE UP
For Oticon Dynamo BTE UP, compatibility is usually determined by the physical coupling between the hearing aid and your ear (earhook, tubing, mould/dome), not by software. Use these checkpoints before you buy:
Earhook type: the elbow-shaped hook attached to the hearing aid. Power models often use a sturdier hook and specific tube sizes.
Tube thickness: common options include thinner standard tubing and thicker power tubing. The wrong tubing won’t seal well or may not fit the hook/mould.
Earmould vs dome: earmould fittings typically use standard earmould tubing; dome fittings depend on the specific adapter and dome system used.
Left/right: many parts are universal, but some fittings (or moulds) are ear-specific.
Most common Oticon Dynamo BTE UP accessory types
1) Earhooks (BTE hooks)
The earhook is the hard plastic piece that routes sound from the hearing aid into the tube. If yours is cracked, loose, yellowed, or whistling suddenly increased, replacing the earhook can restore a tight connection.
Tip: remove and compare your current earhook visually before ordering. Small differences (angle, locking style, tube outlet size) can matter.
2) Tubing (standard or power)
Tubing connects the earhook to your earmould (or to certain domes/adapters). Over time tubing hardens, discolours, or shrinks, which can cause:
Whistling/feedback
Poor sound (thin or “leaky”)
Discomfort from pulling
If you have an earmould, check whether you use standard or power tubing. Power fittings commonly need a tighter seal, so tubing size and stiffness matter more.
3) Earmould accessories
With Oticon Dynamo BTE UP, an earmould is often the core of the fitting. While the mould itself is custom-made by a clinic, you can usually replace the tubing and sometimes the tube lock/retainer (depending on mould design). If your earmould feels loose, hurts, or suddenly whistles a lot, the mould may need re-making rather than just new tubing.
4) Domes (only if your Dynamo fitting uses them)
Some Dynamo BTE UP users may have a dome-based coupling. If you wear domes, the correct choice depends on:
Dome family/system used on your fitting
Size (typically measured in mm)
Vent/opening level (open vs closed vs power) based on your feedback control and bass needs
If you’re unsure whether your Dynamo BTE UP uses domes or an earmould, check for a custom mould shape in your ear. A mould typically fills the concha more and attaches to tubing; a dome is a small silicone tip at the end.
5) Cleaning & maintenance items
Even when the “main” parts are correct, sound can drop if the sound path is blocked. For BTE UP fittings, typical maintenance accessories include:
Cleaning brushes for the earmould and microphones
Tube cleaners / air blowers for moisture in tubing
Drying solutions to reduce moisture-related issues
How to choose the right Oticon Dynamo BTE UP replacements
Use this simple process to reduce mistakes:
Identify your coupling: earmould + tube (most common) or dome-based setup.
Match what you already have: compare earhook shape and tube thickness to your current parts.
Prioritise seal for UP fittings: if you have feedback or weak bass, you likely need the same (or tighter) acoustic setup—not a more open one.
Replace “wear” parts first: tubing and earhooks are frequent culprits before assuming the hearing aid is faulty.
If possible, note any markings on your current tubing/earhook or take a clear photo for comparison before ordering.
Common problems (and what the right accessory fixes)
Whistling/feedback suddenly started: hardened tubing, cracked earhook, loose earmould fit, or blocked sound path. Start with new tubing and check the hook connection.
Sound is weak or muffled: moisture or blockage in tubing/earmould, or tubing is collapsed/hardened.
Fit feels tight or pulling: tubing shrank over time; replace tubing with correct length.
Frequent moisture issues: add drying routine and consider tube cleaning tools.

FAQ: Oticon Dynamo BTE UP accessories
Are Oticon Dynamo BTE UP accessories universal across Oticon BTE models?
Not always. Some items (like certain cleaning tools) are universal, but earhooks and tubing sizes can vary by model and fitting style. Match the physical part you already use.
How often should I replace tubing on a Dynamo BTE UP?
Replace when it hardens, discolours, shrinks, or you notice feedback or poorer sound. Many users replace tubing regularly as part of maintenance, but the exact interval depends on wear, skin oils, and moisture exposure.
I have an earmould—do I need domes?
No. If you use an earmould, you typically replace tubing (and occasionally the earhook), not domes. Domes are used in different coupling setups.
What should I do if I’m unsure which part fits my Dynamo BTE UP?
Check whether you have an earmould or domes, then compare your current earhook and tubing thickness to the replacement options. If you can’t confirm, use a photo of your current parts to match shape and connection style before buying.
