4smarts SoundGlasses Sport glasses
The 4smarts SoundGlasses Sport in black are a modern combination of functional sunglasses with Bluetooth audio technology, designed for active individuals. They provide full freedom of movement and comfort, allowing users to listen to music, make phone calls, and use voice assistants without the need for traditional headphones. Thanks to the open-ear design, the user can hear sound from the built-in speakers while still being aware of their surroundings, which enhances safety during sports activities or cycling. The glasses utilize Bluetooth 5.3 technology, ensuring a fast and stable connection to mobile devices within a range of 10-12 meters.
The Sport model is equipped with TAC photochromic lenses with UV400 filter, which automatically adjust the level of tint to lighting conditions, protecting the eyes from harmful UV radiation. The IP65 rated housing ensures resistance to dust, splashes, and sweat, making the glasses an ideal choice for running, cycling, and other outdoor activities.
The built-in battery with a capacity of 105 mAh provides up to 4 hours of operation on a single charge at average volume, and a full charge via the magnetic USB-C connector takes about 1.5 to 2 hours. Intuitive touch panels on the ear hooks allow for convenient control of music playback, answering calls, adjusting volume, and activating the voice assistant.
4smarts SoundGlasses Sport are the perfect solution for those who want to combine style, safety, and modern technology in one device — ideal for everyday use as well as during sports activities.
