No. HEAVYS Snap-On Shells are designed for visual customization and should not change the normal audio performance of compatible H1H headphones when properly installed.
Make sure each shell is:
- Compatible with your headphones
- Correctly aligned
- Securely seated
- Free from visible damage
Still Need Help?
If you notice an audio issue after installing the shells, remove them and test the headphones again. If the issue continues, email support@heavys.com.
