I have Bose Frames bone conduction sunglasses, but they won't turn on even after charging. The light seemed to flash at one point, but it doesn't work when I try to turn it on. Please understand that this is a junk item before purchasing. If you can fix it, please do! You can use it as sunglasses, but the lenses and frame have minor scratches and dirt. Retail Price: ¥71,500 Accessories: Genuine charging cable (I bought a new one thinking the cable was the problem, used it a few times) Product Description: Sunglasses with built-in Bluetooth and speakers. A key feature is its compatibility with "Bose AR," the world's first voice-based AR (augmented reality) function. With AR using sound as an interface, you can have new experiences hands-free without looking down at your face. By updating the device via the Bose Connect smartphone app, you will be able to use third-party AR functions that will be released in the future. It is expected to be used in fields such as music, games, fitness, travel, and communication. The Bluetooth profiles supported are A2DP/HFP. Small speakers are built into the rear of the temples, and the speakers are positioned to deliver sound directly to the ears. You can listen to music and voice guidance without blocking your ears. The waterproof performance is IPX2, so it is not suitable for use in water sports. The temples have a multi-function button that can be used to turn the power on/off, answer/reject incoming calls, play/pause music, and activate your smartphone's Siri/Google Assistant. The sunglasses lenses block 99% of ultraviolet rays (UVA/UVB). They are scratch-resistant. The hinge of the temples is made of stainless steel with a gold finish. Continuous use time varies depending on the function used, but it is up to 3.5 hours for music playback and up to 12 hours on standby. Weight is approximately 45g.
