ViView Smart Bluetooth Glasses for Men&Women Ultra Loud Volume,Safety Glasses with Bluetooth Speaker Rechargeable LED Lights,20 Hrs Runtime TR90 Frame ANSI Z87.1

A bold innovation from Viview,our G4C smart Bluetooth safety glasses are the result of two years of in-depth market research.Starting from the foundation of safety glasses, our team has designed a product that merges the functions of safety eyewear,headlamp lighting,and Bluetooth audio playback.Perfect for everyday wear and specially engineered for demanding work environments,the G4C stands out with the following unique advantages:<br> Exceptional battery life: Enjoy up to 20 hours of Bluetooth playback and 13 hours of headlamp illumination—twice the battery capacity of competing products.<br> Powerful sound: At just 60-80% volume, the G4C delivers ample sound for daily use. At maximum volume, it outperforms similar products by at least 25%, making it ideal for extremely noisy settings—all while maintaining tuned, reliable audio quality.<br> Unique offline music mode: Comes with 8GB of built-in storage, expandable up to 128GB, so you can play music anytime, anywhere—no network needed.<br> Ultra-lightweight and durable: Weighing only 0.11 lbs and packed with advanced features, the G4C is crafted with high-quality TR90 material throughout both the frame and temples for maximum strength and comfort.<br><br> The maximum volume of G4C is only recommended for short-term use in specific work scenarios.For daily use,it is sufficient to adjust the volume between 60% and 80% when playing music.When the volume of G4C is set to 100%, the sound output from the speakers on both temple tips will reach approximately 100 decibels each.However,prolonged exposure to environments exceeding 80 decibels may pose risks to human health,particularly to the ears and hearing.Therefore,unless under exceptional circumstances,it is strongly advised not to set G4C to maximum volume for playback.<br> Decent Lighting for Close-up Tasks<br> With three adjustable brightness settings, it's the perfect replacement for bulky headlamps when you don't need intense lighting—plus, enjoy extended runtime of up to 13 hours on a single charge.<br> Unique,shadow-free Lighting Design<br> The G4C focuses the beam directly in your central line of sight for incredibly intuitive and convenient use. Premium LED beads emit a subtle, faint blue light that is gentle and easy on the eyes.<br> Interchangeable lenses<br>
