no, nigga, you just put a cap in series with your headphones. it takes care of translating DC to AC all by its lonesome. you also want a series resistor to lower the volume, like 100-300 ohms. (or you could just make the cap smaller to decrease volume.)

you should also add a cap, maybe 10uF, across the speaker coz square waves are harsh to listen to. even more than mom.
