Thank you for viewing. [VR Goggles & Bluetooth Connection] Compared to other VR goggles, the biggest advantage of these VR goggles is that they are connected via Bluetooth. Although they are much more expensive than other regular VR goggles, they are sold at a lower price. The convenience of VR goggles is that they use Bluetooth connection for iPhones and Android phones. The convenience is greatly improved because there is no need to connect with a 3.5mm headphone jack or Apple Lightning. The built-in battery can be used for up to 15 hours with a 2-hour charge. [Ergonomics & Excellent Heat Dissipation] Because VR glasses need to be worn for a long time, we use a safe cushioning material to protect the nose, face, head, and neck. No marks are left on the face even after wearing it for a long time, and it has strong permeability. Strong and fast heat dissipation, no sweat even in summer. The "three-axis fixed head strap" made with an ergonomic manufacturing method does not cause fatigue even after long use, and has excellent elasticity and adjustability. It fits perfectly on the head, so there is no need to worry about slippage or falling off, and it does not put a burden on the head and neck even after long-term use. The front panel has a magnetic adhesive design with excellent heat dissipation and breathability, allowing heat from the smartphone to escape from the inside and preventing the view from blurring. [Stereo Sound Headset] A stereo headset is installed to achieve a more realistic and immersive 3D environment. With headphones equipped with a 42mm large-diameter driver, you can experience immersive sound quality and clearly hear even the monsters and footsteps of enemies in movies. Furthermore, the angle of the headset can be adjusted up and down/back and forth, allowing you to adjust it to the optimal angle.
