If you're used to work with headphones or need a dry sound, use “Phones”.
This is a headphone sound with frequency correction but without spatial emulations. The mode is perfect for editing before mixing and focuses on details: clicks, noise, and other artifacts.
You can take it as an alternative spatial perspective and check the mix using headphones. The dSONIQ Balanced target curve creates a natural frequency balance.
The dry headphone sound is clear, detailed, and wide. However, it doesn't let you understand how your track sounds in real rooms.
