The device
From JCALLY's spec images unless markedThe last detail image (12) on the JM7L page is the spec table of a different product: product name JM10 PRO portable DAC headphone amp (original: 产品名称 JM10 PRO 便携解码耳放), DAC CS43131, 31.25mW@32Ω, 3.27mW@600Ω, Native DSD64/128/256. None of it is used for JM7L.
Image 04 and product gallery, image 5, say the product does not support calls / in-line control; image 08 bottom bar still shows in-line control, portable (original: 线控 便携), likely from the JM7 template. The record follows the explicit special reminder (original: 特别提醒) notice.
The socket housing on the JM7L images is printed JM7 CX31993 Amplifier (the JM7 model name), while the page and plug say JM7L.
