Wireless Earbuds

A basic Bluetooth speaker (China, 300–500 unit run) lands around $8–15; over-ear headphones run $12–25; true wireless earbuds with a charging case run $15–30, driven by the chip and battery in each earbud plus the case.

Closed-back for noise isolation and use in shared or noisy environments; open-back for a more natural, spacious sound in quiet home listening, accepting that sound leaks out and background noise leaks in.

IPX4 for light splash resistance suited to kitchen or patio use; IPX7 for full submersion resistance suited to pool or beach use. Confirm the rating explicitly, since "water-resistant" alone doesn't specify the level.

Typically 300–500 units per model and color, since the internal electronics (chipset, driver, battery) are sourced in batches that need volume to be cost-effective.

Each earbud is a self-contained device with limited internal battery space, so charge lasts only a few hours; the case recharges them between uses and extends total usage to a full day or more.

Newer versions (5.0+) offer better range, lower power consumption, and lower latency than older versions; specify at least 5.0 for a modern product, since older chipsets are being phased out by component suppliers.

Bluetooth speakers and headphones generally fall under HS 8518. Confirm the specific subheading based on whether the device includes a battery, as that can affect classification and shipping documentation.
