Questions about this item

What Bluetooth version do the U9-001 earbuds use, and what does it limit in practice?

They use Bluetooth 5.4 for a stable wireless link to your phone; the standard caps audio quality at the codec level, so high-resolution formats are downsampled during transmission.

What physical items are needed to wear and charge the U9-001 earbuds?

The box includes two earbuds, three pairs of silicone tips in small, medium and large sizes, a wireless charging case and one charging cable for the case.

How do I pair the U9-001 earbuds for the first time, and what step do people often miss?

Open the charging case to activate pairing mode, then select the earbuds on your device; many users forget to remove the protective film from the earbud contacts before the first charge.
