K89 Business Lavalier Single Ear Bluetooth Earphones: Bluetooth version: V5.4
Ever been in the middle of a call when your earphones decide to take an unscheduled break? Not with the Business Lavalier Single Ear Bluetooth Earphones. These little wonders are a game-changer for busy professionals who can't afford to miss a beat. With Bluetooth V5.4, they keep you connected up to 10m away, and just 20 minutes of charging gifts you a whopping 12 hours of talk or music. And get this – they can sit idle for up to 6 months without throwing a tantrum. Talk about reliability!
But wait, there's more (because who doesn't love a good bonus?):
- Juggling work and personal life? The Dual Device Connection lets you switch between two smartphones smoother than a hot knife through butter.
- Ever been caught off-guard by a dead battery? The Battery Level Display keeps you in the know, so you're never left guessing.
- Whether you're team English or team Chinese, the Bilingual Voice Prompts have got your back, making setup a breeze.
- Even if your phone's on silent, the Incoming Call Vibration Alert makes sure you're always in the loop – perfect for when you're pumping iron or stuck in traffic.
- And for the pièce de résistance, the Smart Voice Notifications whisper sweet nothings (well, caller IDs and earphone statuses) into your ear, keeping things hands-free and hassle-free.
