#s 1 and 4 and the last one (same as #1) are the best.
When referring to one headphone or one headset, you say "a headset." When referring to headphones, you don't need an article (except maybe "the" if you just want variety!).
1. He is listening to music with headphones.
2. He is listening to music with a headphone.
3. He is listening to music with headsets.
4. He is listening to music with a headset.
5. He is listening to music with headset.
(Which expressions are correct? Would you let me know how to use the articles in these sentences?)
He is listening to music with headphones.
