OlaFriend Wireless Earphones, Ear-Hook Type, AI-Equipped Model Functionality confirmed. It connects via Bluetooth with the seller's own devices. It seems AI features can be used with the dedicated app. I haven't used any functions other than listening to audio, so I cannot answer questions about the features. Please understand. Since it's a Chinese manufacturer's product, the guide voice is in Chinese. It's also unknown whether there is a language switching function. #WirelessEarphones #WirelessEarphonesAlwaysOn #WirelessEarphonesLongTime #ChineseGadgets
