The Kenwood HS-5 headphones are designed for radio communications and sound very good with the K3. They are mono but it is easy to convert them to stereo. The cord has 3 wires: ground, left speaker, right speaker. Left and right speakers are wired together in the mono plug AND in the earpiece where the cord goes in. Open the earpiece: Use a tool that won't leave scratches on the earpiece. Pry off the perforated metal cover being careful not to damage it. Pry off the plastic cover, it is held in place by 2 clamps. You will feel where they are. Use gentle force. Cut the red wires off the speaker, solder them together then insulate them. Leave the white and black wires in place. I would not solder the red wire off, it is too big a danger to unsolder the very very thin wire going from the PCB to the innards of the speaker. Re-assemble. Replace the Mono-plug with a stereo plug. Solder the black wire to the ground ring. Red wire to tip and white wire to the middle ring, or vice versa, depending on which side you like to have the "right" channel AND on which side you like to have the cord.
You'll be rewarded with plenty of audio and good sound.
