I have an old set of full size sony headphones that give way more than enough audio output for my moderate hearing loss. Most headphones are rated for the level of audio out for power in, and the ones that cover the ears seem to be more comfortable for me and reduce any outside noise.
How you set up the agc effects the audio output level of the k2, and there are resistors that can be changed or eliminated in the headphone circuit, or you could plug the headphones in the ext speaker output. You can also change the tone of the CW to get in a range that you might hear better, I seem to like a much higher CW note than many operators as I am up against the BFO range limit on my K2.
