ReSound Key BTE Series Accessories & Compatibility Guide | Japebo
Looking for the right accessories for your ReSound Key BTE series hearing aids? This guide helps you identify what fits, how to choose the correct parts, and how to solve common fit and sound issues. ReSound Key BTE models can be used with different ear-coupling setups (such as thin tubes with domes or custom earmolds), so compatibility depends on your exact configuration—not just the hearing aid name.
What “ReSound Key BTE” means for accessories
BTE means “behind-the-ear.” With ReSound Key BTE hearing aids, the accessories you replace most often are typically the parts that sit in or near the ear: domes, thin tubes (if your model uses them), and wax protection (varies by receiver/tube setup).

The key to choosing correctly is understanding whether your ReSound Key BTE is fitted as:
1) Thin-tube + dome (open fit), or
2) Earmold + hook + tubing (more closed fit), or
3) RIE/RIC-style receiver setup (less common for pages labeled “BTE,” but sometimes mixed in depending on naming or retailer listings).
