Custom Molded Fiber Tray Earphone

Earphone trays across a model line

Audio brands rarely launch one earphone. They launch a line of four or five, each with a different case, and each needs a pack. That makes tooling economics the real decision, not tray design.

We quote both routes so the choice is explicit:

• Dedicated tool per model - the cleanest cavity fit and the lowest unit cost, best when a model runs in high volume for years.
• Shared tray plus insert - one outer tray across the line, with a small interchangeable cavity part per model. Lower total tooling, slightly higher unit cost.
• Mixed-size trays for ranges that pair a charging case with ear tips, a cable and a pouch.
• Display variants with an open face, for counter display rather than transit.

As a rule of thumb, below about 20,000 units per model the shared-tray route usually wins on total cost, and above it the dedicated tool does. We will run both numbers against your forecast rather than quoting one.

MOQ 10,000 pieces per design; tooling 7–15 days, production 15–25 days after sample approval. Send the cases in the line plus a volume forecast, or see the consumer electronics range.
