Smart Noise Cancellation

These wireless earbuds use active noise cancellation and four microphones with AI-powered noise reduction to suppress ambient sound during music playback and calls. They are intended for commuters, office workers and travellers who want a quieter listening experience without bulky over-ear headphones.

Bluetooth 5.4 Practical Limits

The earbuds connect via Bluetooth 5.4 and require a source device that supports this version for full feature operation. Battery life is rated at five hours per charge with the case providing a total of 24 hours, so users planning longer sessions away from power will need to recharge the case periodically.

Build Quality and Daily Use

Each bud weighs 41 grams and uses an in-ear design with silicone tips for a secure fit during exercise or extended wear. The charging case includes an LED display that shows remaining power for both the case and the earbuds, removing guesswork about when to recharge. Touch controls handle playback and calls without reaching for the phone.

Questions about this item

How do I choose between the AUT211 and AUT211N versions?

What does 5 hours of earbud playtime mean for daily use?

What does Bluetooth 5.4 cap in real-world performance?

It limits the link to the Bluetooth 5.4 specification, governing range, latency and audio codec support for iPhone, Android, tablet or laptop connections.
