1650 Double Horns

The XO 1650 Double Horn with Geyer wrap was designed and developed in collaboration with highly respected engineers, technicians, and hornists. With a warm focused tone and exceptional slotting, it merges performance and practicality.

"3D" F Side Tube

The reimagined one-piece F tube is produced from a groundbreaking new 3D bending process, allowing notes to slot more easily while providing outstanding overall response.

One-piece Leadpipe

The one-piece leadpipe provides reduced resistance and superior intonation. It produces complex harmonics with a consistent playing feel.

Adjustable Thumb Key Lever

Multi-axis positioning ensures relaxed, stress-free hand position.

Adjustable Finger Hook

The clamping mechanism allows for easy adjustment of the pinky finger hook to best suit the hand and playing style of the performer.

String Lever Action

Traditional string linkage provides smooth and quiet synchronous response of lever and rotor.

Phosphor Bronze Bottom Caps

Advanced metallurgy offers increased resistance to wear and corrosion.
