Is it enough for your headphones?

JCALLY rates the JM45 at 35.15 mW into 16 Ω. Below is how much of that is left to spare for each kind of headphones when you listen loud, with peaks at 110 dB. A figure marked est. is worked out from that rating.

The spec table names the product 'JM45C audio adapter cable' (original: JM45C音频转接线); the page title, headings and body print say JM45.

Product details, image 6, places the label 'CS43198' under the ESS logo while the same panel and every other panel name ESS ES9318; the intro and product gallery, image 5, write ES9318C. The catalog takes the spec table value ES9318.

Product details, images 7 and 9, say pure-silver core (original: 纯银线芯); Product gallery, image 5, says 8-strand silver-plated cable (original: 八股镀银线).

Product details, image 2, on this USB-C page shows a device printed 'JM45L' with the caption 'JCALLY JM45L Lightning portable decoder headphone amp' (original: JCALLY JM45L Lightning 便携解码耳放); it is the Lightning sibling's panel, so nothing from it except the shared call warning is used here.
