Is it enough for your headphones?

JCALLY rates the JM20 at 31.25 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.

Product details, image 5, says recording uses an HD ADC chip supporting 24bits/48KHz (original: 录音采用高清ADC芯片支持24bits/48KHz采样), while the spec table and images 01 and 07 say HiFi music only, no calls or inline control (original: 仅支持HIFI音乐，不支持通话线控). The catalog follows the spec table: no microphone/call support.
