With Bluetooth 5.2 connectivity, hybrid ANC, and a sleek charging case, the Spirit S3 aims to satisfy commuters, gym users, and audiophiles seeking convenience without compromising audio quality.

Key Features of the Edifier Stax Spirit S3

1. 40 mm Dynamic Drivers
   Delivers balanced bass, clear mids, and detailed highs for a rich, full-range listening experience.

2. Hybrid Active Noise Cancellation
   Combines feedforward and feedback microphones to reduce up to 35 dB of ambient noise, perfect for noisy environments.

3. Bluetooth 5.2 with aptX Adaptive
   Ensures stable, low-latency wireless streaming and high-resolution audio when paired with compatible devices.

4. Transparency and Ambient Modes
   Toggle modes to let in environmental sound when you need to stay aware—ideal for street crossings or office chatter.

5. Comfort-Focused Design
   Lightweight earbud housings, three sizes of silicone tips, and IPX5 water resistance make the Spirit S3 suitable for long sessions and workouts.

6. Touch Controls and Voice Assistant
   Intuitive tap gestures on the earbud surfaces let you play/pause, skip tracks, adjust volume, answer calls, and summon your phone’s voice assistant.

7. Compact Charging Case
   Provides up to 24 hours of total playback (6 hours per charge in the buds plus 18 hours reserve in the case) and supports USB-C fast charging.

Performance and Efficiency

In listening tests, the Spirit S3 produced punchy yet controlled bass that never overpowered vocals or midrange detail. The Hybrid ANC effectively silenced background chatter and transport noise without introducing noticeable hiss. Bluetooth pairing was seamless, maintaining a stable connection through walls and across rooms. Call quality remained clear, thanks to beamforming mics that focused on voice and rejected wind and ambient noise.

Battery Life and Charging

Each earbud runs for about 6 hours on a single charge with ANC enabled, and up to 8 hours with ANC off. The pocket-sized charging case carries enough power for three full recharges, delivering a total of 24 hours of use. A 15-minute quick charge yields roughly 2 hours of playback, while a full case recharge takes about 1 hour via the USB-C port.
