Minimalist Plug-In Mantra Box

I’m sourcing a manufacturer-developer who can turn my supplied 3- to 5-minute MP3 tracks into a simple, plug-in mantra chanting box. The look I want is clean and minimalist—no ornate casing, just an unobtrusive unit that blends into any small altar or bedside table. Because these will stay permanently connected to mains power, there is no need for batteries.

Key functional points:
• Standard playback quality is fine; clarity matters more than audiophile specs.
• A smooth volume control wheel or slider must be included.
• The track should loop automatically, so a built-in repeat mode is essential.

Scope of this run:
– 200 finished pieces, each loaded with a different mantra that I’ll provide in MP3 format.
– All units must pass a quick burn-in test to confirm continuous looping without glitches.
– Supply power leads compatible with 220 V AC (India). If you typically ship another plug type, let me know so we can discuss adapters.

When you quote, please break down:
1. Tooling or mould cost (if any)
2. Per-unit production cost at 200 pcs
3. Lead time for first article approval and for the full batch

Dispatch should include secure, retail-ready packaging that protects the minimalist aesthetic. Looking forward to your best price and a clear timeline so we can start chanting soon.
