Xiaodu Du Smart Buds, Bluetooth wireless earbuds in white. Includes earbuds and instruction manual. Purchased on Amazon in November 2021. The dedicated connection app has a transcription function. The main unit battery has deteriorated over time, and the battery drains faster from a full charge, but it can still be used for several hours, so it's fine for casual listening. - Brand: Xiaodu - Model Name: Du Smart Buds - Color: White - Bluetooth: Yes Thank you for viewing.
