Key features

Shark fin ear wings — ultra-thin low-profile design

The LY9 use a shark fin ear wing structure designed to hold the earbud securely and low-profile against the ear — intended to reduce discomfort during side sleeping. The earbud profile is described in the source as mini and ultra-thin. Specific earbud dimensions and weight are not individually stated in the source specification. Ear wing and earbud materials are not individually specified in the source.

Bluetooth 5.4 — 10mm driver — gesture control — up to 10m

The LY9 uses Bluetooth 5.4 with a 10mm dynamic driver. Range is up to 10m as stated in the source. Gesture control on the earbud surface manages music playback, call answering, and volume — specific gesture mappings are not individually detailed in the source specification. Bluetooth profiles and latency are not individually specified in the source beyond the BT 5.4 version described.

Physical noise isolation — no ANC

Noise isolation on the LY9 is achieved through the physical fit of the earbuds in the ear canal. The LY9 does not have active noise cancellation (ANC). No ANC or ENC is mentioned or confirmed in the source specification. The physical fit is described in the source as providing a passive seal. This means ambient sound attenuation depends on earbud fit rather than electronic processing.

Each earbud contains a 25mAh battery providing 4–5 hours of use per charge as stated in the source specification.
