Is it enough for your headphones?

JCALLY rates the JM9 at 25 mW into 32 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 product intro says the JM9 is equipped with the ES9280AC PRO from ESS Technology, and product gallery, image 5, says upgraded flagship chip ESS ES9280AC PRO (original: 升级旗舰芯片 ESS ES9280AC PRO). The spec table, product details, images 3, 6, 7 and 8, and the print on the housing all say Cirrus Logic CS46L41. The catalog uses the spec table value; the page may describe two hardware revisions.
