Yes, I can certainly help you master music for headphones. Mastering is the process of ensuring the mix is well balanced and ready for release. When mastering for headphones, there are a few things to keep in mind:

1. **Frequency Response**: Headphones typically have a different frequency response compared to speakers. They tend to be more accurate and less boomy, so you might want to adjust the EQ slightly to compensate for this. Some headphones can also boost the lower mids, so you might want to cut a bit around 300-400 Hz.

2. **Stereo Image**: The stereo image can be more pronounced on headphones, so be careful with panning and stereo width. It’s also worth noting that headphones can sometimes create a “hole in the middle” effect, where the center seems empty, so make sure there’s enough going on in the middle frequencies.
