01
Ear interfaces
Ear clips provide localized contacts. Earbuds integrate contacts into an in-ear form. Ear hooks distribute weight or stabilize the interface. Fit, pressure, material, geometry, and placement affect contact.
02
Control architecture
Some systems place session controls on the device; others use a phone or research console. Documentation identifies where stimulation control resides, which functions work offline, and what data are collected.
QUESTIONS
Frequently asked questions
Does device shape determine effectiveness?
No. Form factor alone does not establish delivered dose, safety, or effectiveness.
Are app-connected systems always more capable?
No. Capability depends on the device architecture, controls, software functions, and evidence.
