SOULWIT Headband Hinge Replacement for Sony WH-CH720N — Pink swivel pivot, easy DIY repair

Replacement swivel hinge and pivot joint designed to restore folding, rotation, and secure headband attachment on Sony WH-CH720N wireless noise-canceling headphones.

If your Sony WH-CH720N headphones have a broken or loose hinge that prevents proper folding or causes wobble, this SOULWIT pink plastic hanger bracket is made to bring them back to normal. Specifically engineered for the WH-CH720N model, the part replaces the headband hinge assembly and returns smooth swivel action and structural stability without having to buy a whole new headset.

Will this hinge fit my Sony WH-CH720N headphones?

Yes — the part is manufactured to match the WH-CH720N’s original hinge geometry and mounting points. It is not compatible with other models such as WH-CH700N or WH-CH710N, so confirming your headphone model is important before purchase.

• Exact fit for Sony WH-CH720N only.
• Same screw locations and pivot pin alignment as OEM.
• Sold as replacement hinge pieces for left or right side.

How difficult is installation and what tools do I need?

Installation is intended for at-home repair and comes with step-by-step instructions in the packaging. Basic hand tools are typically all that’s needed and the process focuses on removing a few screws, replacing the hinge, and reassembling the headset.

• Includes illustrated instructions for clarity.
• Simple screwdriver set and steady hands recommended.
• Average repair time: 10–30 minutes depending on experience.

Will this part make my headphones as durable as new?

The SOULWIT hinge is produced from durable plastic designed to withstand repeated folding and swivel motions found in everyday use. While replacement restores mechanical function and stability, overall longevity will also depend on handling and strain on the headband.

• High-quality plastic improves resistance to routine wear.
• Restores correct rotation and folding action.
• Recommended to avoid excessive bending or force after repair.

What comes in the package and does SOULWIT offer support?

Each package includes the hinge/pivot replacement pieces and clear installation guidance so you can complete the repair quickly. SOULWIT provides customer support for installation questions and ongoing development of ergonomic accessories.

• Replacement hinge components in pink color.
• Installation guide with step-by-step visuals.
• Customer service for fit or installation issues.

Who is this for? The SOULWIT hinge replacement is ideal for WH-CH720N owners who prefer repairing over replacing their headphones, DIYers who want an affordable fix, and anyone needing a matching pink hinge to restore proper folding and swivel action. If you own a different Sony model, please verify compatibility before ordering to ensure correct fit and performance.
