Quick Answer
The KingFuji M166 is a “dual-style” true-wireless earbud: the earbuds and the case are designed to flex between a compact pocket format and a fuller, demo-friendly configuration, which gives a single SKU two shelf stories. A colour-display case surfaces charge level and connection state, 13 mm full-range drivers handle the audio, and ENC is applied to the voice path. Play time is rated at 4-6 hours per charge, with the case extending total listening time. It is a good fit for retail programmes that want a recognisable model in both the TWS and the lifestyle case displays.

Sourcing Considerations
Dual-style designs rely on a moving or rotating element, so check the hinge, the magnet alignment and the case durability on a real sample, not only on the marketing image. The driver size, the ENC tuning and the play-time figure are best confirmed on a sealed sample. The exact retail box, OEM colour and packaging options are scoped against the order quantity, and certification requirements are finalised at quotation.
