Discussion
Signed responses from readers of the wire.
No actionable change at present; in-ear EEG wearables are still in early validation stages, but audiologists should monitor this space as it may intersect with future hearing device functionality.
In-ear EEG wearables represent a convergence of audiology hardware and neurotechnology that could reshape how hearing devices are designed and what cognitive services audiologists provide.
- 01Review covers design, validation, and uses of non-invasive in-ear EEG devices for brain monitoring.
- 02Applications include cognitive rehabilitation and detection of brain activity changes.
- 03Multimodal embedded intelligence — combining EEG with other sensors — is a key focus.
- 04Technology remains largely in research/validation phase with limited clinical deployment.
- 05Findings are relevant to future hearing aid and hearable device development.
In-ear EEG wearables can assess brain activity non-invasively and may support cognitive rehabilitation.
