Spark Ring Debuts AI-Powered Wearable for Instant Voice Capture

The device, a zirconia ceramic band weighing just 2.8 grams, operates on a simple premise: recording should not require a screen. By double-tapping the ring, users trigger a noise-reducing microphone capable of picking up speech from up to five meters away. The audio is sent via Bluetooth to a paired iOS or Android device, where it is transcribed and organized into notes or tasks.

Designed for all-day wear, the ring features an IP68 waterproof rating and a battery that charges in 30 minutes, providing eight hours of continuous recording. Founder and CEO Charley Tang emphasizes that the hardware is built to bridge the gap between intent and action without tethering the user to a digital display. To address data security, the company utilizes a local transcription process, ensuring audio files remain on the user's device in compliance with GDPR and CCPA standards. Early backers can secure the device through the crowdfunding campaign at a starting price of $159, with global shipping scheduled for December 2026.
