A comprehensive summary of modern custom rechargeable in-ear hearing aid technology.
Rechargeable hearing aids have been around for many years. Leading German manufacturer Siemens Hearing Instruments (now Signia) originally paved the way with behind-the-ear rechargeable models, while Hansaton pioneered the earliest inductive rechargeable custom in-ear hearing aids.
Early iterations relied on battery technologies that degraded rapidly across repeated charge cycles. However, rapid advancements in lithium-ion and custom moulding techniques mean that all leading hearing aid manufacturers now offer high-specification rechargeable custom in-ear hearing aids—a milestone accelerated by Starkey's landmark custom rechargeable release in 2020.
When selecting a modern rechargeable hearing aid, understanding the practical differences between Inductive Charging and Contact Point Charging systems is essential for long-term daily satisfaction.
| Feature | Inductive Charging | Contact Point Charging |
|---|---|---|
| Charging Speed & Efficiency | Slower overall charging times due to less efficient wireless energy transfer across the magnetic field. | Faster charging times driven by direct, highly efficient metal-to-metal energy transfer. |
| Ease of Placement | Varies by manufacturer. Some models feature custom-moulded insert trays for precise placement, while others use generic trays. | Features magnetic alignment contacts that snap the hearing aids into place easily, ideal for users with dexterity issues. |
| Visual Identification | Smooth outer casing with zero exposed charging pins or metal contacts. | Clearly visible gold or bronze metal contact points on the hearing aid shell. |
Our clinical choice varies across individual makes and models because specific pros and cons apply depending on the manufacturer's charger architecture.
For instance, certain ReSound inductive charging units can lead to unexpected service delays. Similarly, Signia SILK and Active rechargeable in-ear devices can be fiddly to seat correctly and may involve a more convoluted repair process if dock alignment issues occur.
At Crystal Hearing, we generally favor contact point charging systems for their consistent ease of placement and straightforward ongoing serviceability.

The lithium-ion battery inside the hearing aid and the portable charger is engineered to last approximately 4 years, by which time cells typically retain around 80% of original operating capacity. When required, the internal battery is replaced directly by the manufacturer and is fully covered during the device warranty period.
