Audio Performance: The Open-Ear Revolution
The core USP of the Fire Boltt Fire Lens Dune Smart Glasses is the Open-Ear Audio Technology. Instead of plugging buds into your ear canal, the sound is directed toward your ears from the temples.
- Situational Awareness: This is a game-changer for Indian roads. You can listen to your favourite Bollywood tracks or podcasts while still hearing the honking of a car or the announcement at a railway station.
- Sound Quality: While they won’t replace high-end audiophile headphones for deep bass, the 360° acoustic design provides surprisingly clear mids and highs. It is perfect for casual listening and crystal-clear voice calls.
- Privacy: Thanks to directional audio, the person sitting next to you won’t hear your conversation unless you have the volume at the absolute maximum in a very quiet room.
Connectivity and Smart Features of Fire Boltt Fire Lens Dune Smart Glasses
Equipped with Bluetooth 5.3, the Fire Boltt Fire Lens Dune Smart Glasses offer a stable connection with both Android and iOS devices. The pairing process is instantaneous.
The smart touch controls located on the temples allow you to:
- Play/Pause Music: A simple tap on the side.
- Take Calls: Answer or reject calls without touching your phone.
- Summon AI: Whether you want to “Hey Siri” or “Okay Google,” a quick gesture activates your voice assistant, allowing you to send WhatsApp messages or get navigation directions hands-free.
