Short answer: the Audio Pro C3 ranks #1 of 1 powered desktop speakers by sound quality at $330; the Audio Pro C5 MkII ranks #1 at $300. With prices this close, go by the sound-quality ranking rather than the cost.
On the Audio Pro C3 side: Set treble to max and increase bass a little to get it neutral. Has a battery. Set against that: A bit muffled and missing midrange detail.
What the Audio Pro C5 MkII offers: Pretty neutral sound. Wifi. The tradeoff: No battery.
Buy the Audio Pro C3 when the price outweighs sound quality for you, and the Audio Pro C5 MkII when the price outweighs sound quality instead.
