About TRN company

The TRN brand belongs to Dongguan Zuodu Acoustic Technology Co., Ltd. A high-tech enterprise engaged in Hi-Fi (High Fidelity) headsets, sports Bluetooth earphones, TWS Bluetooth earphones, and related fields. Now it integrates self-owned brand products, ODM and OEM. Each TRN product has earphone enthusiasts involved in the development process to ensure that it has the best performance and durability.

Each TRN earphone has a different focus. However, to please the ears' obsession with heavy bass, TRN deliberately enhanced the excitement of this part of the low-frequency area! The overall style is relatively deep, efficiently controlling the omnivorous balanced earphones of rock, pop, symphony, and large weaving styles.

Today's flagship product is TRN BAX Pro. The product matures step by step, but the most important thing is the sound. While the plug-in cable method is not new, TRN earphones also have a Bluetooth upgrade cable, silver-plated upgrade cable, balanced cable, and other options.
