Oraimo Spacebuds Air Otw-324s *38 Hours* Smart Finder

Uses Bluetooth 5.4, giving a stable, modern wireless connection. Battery life is very good: up to 6.5 hours on a single charge of the earbuds, and up to 38 hours total when using the charging case. The earbuds are lightweight (~4 g each) and designed for a half-in-ear fit, which many people find comfortable for long listening sessions. Extra features: “Smart Earbud Finder” — you can use the companion app to make the earbuds emit sound so you can find them if you misplace them. “Sound360 Spatial Sound” — a surround-sound / spatial-audio mode (via the ORAIMO app) for a more immersive listening experience. “AI Call Noise Cancellation” — dual microphones with AI-based noise filtering aim to improve clarity of calls even in noisy environments. Fast-charge: a 10-minute quick charge reportedly gives ~2 hours playback.
