Purchased in January 2020. I opened the box once, but I bought it by mistake, so it's almost unused. I don't know how to use it, so I haven't confirmed its operation. Please understand this. -------Quoted from the purchase site below----- 【Aspherical Optical Lens】 This product uses an aspherical optical lens and has functions to cut blue light and protect against electromagnetic radiation, reducing eye pain, preventing glare, and alleviating eye strain. 【Pupil/Focal Distance Adjustment】 Since pupil distance and focal distance vary from person to person, you can freely adjust the focus on the goggles to set it to the most comfortable viewing state. People with nearsightedness can also experience VR with the naked eye through adjustment. (It may not work for those with extreme nearsightedness.) 【Accessories】 Bluetooth controller & earphones. If you purchase this product, you will receive a Bluetooth controller & earphones as a bonus. The earphones are 3.5mm plug-type earbuds, and the Bluetooth controller uses 2 AA batteries (batteries not included). Note: Due to the closed nature of the iOS system on iPhones, compatibility with the Bluetooth controller is not good. When connected, you can only adjust the volume; please understand that this is not a defect. 【Reliable Service】 Includes a Japanese instruction manual, 24-hour after-sales service, and a 365-day warranty.
