The buyer had already shortlisted three factories before this conversation started. The margin squeeze in the category pushes buyers toward factory-direct programs with test evidence.
Once the field testers logged 200 hours of playback, Robert Sullivan selected MistAirHome as their speaker manufacturing partner. What closed the deal was not the unit price but the test report in the appendix.
The warehouse had a shelf of returned units with dead batteries and two with broken USB ports.
A single customer complaint exposed a pattern the team had not connected. A tour operator counted how many guests asked to borrow a charger after a day of shared music; the number decided the next speaker order.
Field case: A trekking outfitter in Manila ran guided multi-day hikes where guests shared one speaker. A 6-hour unit died on day one; the MS-LB's 42-hour runtime covered the whole route, and the guides now carry it as standard kit rather than a luxury.
Why it matters for global buyers:
MistAirHome runs OEM and ODM programs for buyers who want their own speaker line without building a factory. Customization covers:
Inside, the board layout separates the amplifier from the antenna so pairing stays stable at high volume.

Buyers who ship containers of speakers need more than a price list. The production and QC flow below is what lets a distributor open a carton and trust what is inside:
Lot samples from every production run are measured for playtime, water resistance and distortion before the cartons are sealed, and the numbers are recorded per serial batch. A buyer can request those records with any order.
Put side by side with the alternatives the buyer had been using, the difference showed up in test time, not just features.
