1. Core Hardware
Audio: Open-ear mini speakers (similar to those on inexpensive bone conduction headphones) that allow the user to hear ambient sounds while listening to brief audio clips.
Battery: Minimal power, around 100-200 mAh (1-2 hours of standby, enough for very short active use).
Processor: Lightweight, low-power processor (ARM Cortex-M0 or similar) adequate for Bluetooth audio handling.
2. Connectivity
Bluetooth: Bluetooth 5.0 for simple and reliable pairing with iOS devices to deliver audio instantly and with minimal delay.
3. User Interaction
Controls:
Single button for start/pause audio, with no need for volume control if the volume is preset to an ambient-friendly level.
Voice Activation: Not necessary but could add convenience if very basic (e. G., simple "start" command).
4. Form Factor
Frame: Lightweight, durable plastic frame with minimal adjustments, given the short-duration use.
