The charging case is a fidget spinner - a genuine one, not a gimmick moulded into the lid. TravelerAI Spin is a pair of open-ear Bluetooth earbuds with real-time translation across 164 languages: hand the second earbud over and both sides follow the conversation live. The open-ear fit rests outside your ear canal, so you still hear the airport, the street and the person in front of you. Bluetooth 5.4, around seven hours a bud, and a 380 mAh spinner case that charges over USB-C. Translation runs in the free Ear Dance app, included for the life of the product, and needs mobile data or Wi-Fi. | Harmonix | | TravelerAI Spin Open-Ear Translator Earbuds | Fidget Spinner Case, Bluetooth 5.4 | Black | Best Buy
