Are dongles for audio actually noticeably more power-hungry than a wired connection?

The device is still a digital audio device, requiring a DAC for output and an ADC for input to connect to your analog headphones and microphone. I don't see why putting the DAC and/or ADC in a dongle would use more power than putting them in the device.

I'd argue that the DAC and/or ADC are best placed as close to the headphones and mic as possible. If I'm using very high quality headphones or mics I'm going to want a very high quality DAC/ADC. If I'm using low quality headphones or mics I'm fine with a lower quality DAC/ADC.

With the DAC/ADC built into the device I'm either limited by the quality the device maker chose or am paying for more than I need.

In practice a good phone amp and DAC such as those in the LG V series is the best audio quality you can get without massive boondoggles.

A good amp/DAC combo in the phone is much cheaper than an external amp/DAC of similar quality.
