  • What is the difference between “S” headphones and “X” headphones?”

    The S-family of headphones (S3m, S4, S4i, S4A) all using dynamic moving-coil drivers (similar to your typical speaker woofers), while the X-family of headphones (X4i, X6i, X7i, XR8i, X11i, X12i and X20i) all use balanced armatures. So how do you decide what’s best for you? If you’re in the mood for a full soundstage and thumping but tight bass, and you’re on somewhat of a budget, we recommend the S-family. If you’re looking for clear, crisp, impeccable detail with warmth in the lower octaves like you’ve never heard before, the X-family might be more your cup of tea.

  • Do you have out of warranty repair options for your headphones?

    Due to the size and nature of our headphones, we unfortunately do not have a non-warranty repair option.
