Bluetooth neckband earphones

The bluetooth neckband earphones is built on a 8mm dynamic driver paired with a small signal processing board that handles noise gating, equalisation presets and codec negotiation. The shell is finished in a matte polymer that resists fingerprints, and the seams are ultrasonically welded rather than glued, which keeps moisture out during the sweat and rain testing the Yiwu bench performs on every batch. Firmware is upgradable through the companion application, so equalisation curves and button mapping can be refreshed after the unit has already shipped to a customer.

On the bench the unit delivered Bluetooth 5.1, SBC and AAC codec, battery 200mAh in the neckband, 18 hours playtime, and magnetic earbud tips that pause playback when joined. Latency in gaming mode where fitted measured under 90 milliseconds, low enough that lip sync drift was not perceptible during video playback. Call clarity was assessed in a simulated street environment at 70dB ambient noise, with the far end reporting intelligible speech throughout the test.

The typical buyer is delivery drivers and warehouse staff needing all day wear without a charging case to lose. Retailers selling into this segment report that shoppers compare battery life and fit above all else, both of which this unit was designed to satisfy, with ipx4 sweat resistance acting as the point of difference that closes the sale against otherwise similar looking imports.
