Know before you buy
The J-Mount system allows you to swap between titanium, brass, and stainless steel nozzles. Each material subtly alters the acoustic characteristics, letting you fine-tune the sound profile to better match your personal preferences.
The full stainless steel construction is designed to minimize unwanted resonance and vibration. By creating a rigid housing, it helps the drivers produce cleaner, more precise audio with tighter bass response.
Yes, these headphones use standard MMCX connectors. This makes it easy to replace the included high-grade OFC cable if it becomes damaged or if you wish to upgrade to a balanced cable.
No, the HA-FD01 relies on passive noise isolation. By using the included Spiral Dot Plus earpieces to create a proper seal in your ear canal, the physical design blocks out ambient noise without the need for electronic processing.
Yes, they feature a standard 3.5mm gold-plated plug, making them compatible with any device that has a headphone jack. If your phone lacks a jack, you will simply need a standard USB-C or Lightning to 3.5mm adapter.
The Fine Adjust Mechanism allows you to rotate the nozzle position within the housing. This adjustment helps you achieve a more comfortable fit and can subtly change the angle of the sound delivery to your ear canal.
