Overview
A Spanish audio brand serving home and outdoor audio markets in Spain and Southern Europe. The project began with a customized TWS paired speaker system and grew into a long-term ODM relationship.
The Challenge
Two speakers had to connect, synchronize and hold stable left-right timing, resist interference in home and outdoor environments, meet CE-RED and RoHS requirements, and keep identical software versions across repeat production batches.
The Solution
FLS optimized the TWS software and repeatedly tested synchronization and connection stability, extending anti-interference validation beyond lab conditions. Structure and LOGO appearance were customized, CE-RED and RoHS compliance supported, and a dedicated TWS pairing inspection added to production with locked hardware and software versions.
Building a Reliable TWS Stereo Speaker System
True wireless stereo lets brands deliver wider sound and flexible home and outdoor audio. But a reliable TWS paired system is far more demanding than a single speaker: two devices must connect, synchronize and hold stable left-right channel performance.
The Challenge
A Spanish audio brand serving Spain and Southern Europe needed stable TWS interconnection, strong stereo performance, differentiated appearance and European compliance, while keeping software versions consistent across repeat batches.
FLS Solution
FLS optimized the TWS software configuration and repeatedly tested left-right synchronization and connection stability, extending anti-interference testing beyond lab conditions. Structure and LOGO appearance were customized, CE-RED and RoHS documents delivered, and a dedicated TWS pairing inspection added to production with locked hardware and software versions.
Project Results
The first batch reached Spain and the product entered offline retail and e-commerce, later expanding across Southern Europe. TWS pairing and stereo performance stayed stable with no batch-level functional problems, and the customer continued placing repeat orders.
The Result
The first batch was delivered to Spain and the product entered offline retail and e-commerce channels, later expanding across Southern Europe. TWS pairing and stereo performance remained stable with no batch-level functional problems, and repeat orders continued.
