Outputs and power
Not stated: gain, supply voltage.
The table gives output drive (original: 输出推力) 1.05Vrms @300Ω (a voltage) and names neither socket nor model; no mW figure is stated, so power[] stays empty.
Image 05 callout says gold-plated 3.5 mm socket (original: 3.5 mm母座采用镀金材质), while the product has 2.5 mm or 4.4 mm balanced sockets per the table; likely a template carry-over, not used.
The device
From JCALLY's spec images unless markedImage 02 writes CX31988 in the first line and CX31998 in the second; the spec table says Conexant CX31988 (original: 科胜讯CX31988). The record uses the table.
