- Origin - KOSO was officially established due to the necessity of an independent brand for future market marketing. In 1989, KOSO was registered as a trademark for Tong Ya. The name KOSO is derived from the Japanese words for "conception" and "high speed"; conception represents creativity, while high speed represents high-performance expression. Combined, it reflects the company's desire to use creativity to create high-performance products! - Spirit - The brand spirit KOSO pursues is based on quality, technology, and service, built on a foundation of integrity and mutual trust. We persistently uphold this attitude, not only manufacturing high-quality products but also pursuing product innovation and quality improvement, hoping to bring more excellent products to everyone. - Brand Journey - Pursuing perfect product design and quality has always been our goal. Therefore, KOSO constantly pushes itself by improving its own technology. We firmly believe that brand image and product quality are synonymous! Thus, the company is strict with product development, production processes, and quality control, hoping to reach the goal of high quality while stepping onto the world stage. In the future, KOSO will continue to develop more user-friendly and innovative products, aspiring to become the next world-leading brand from Taiwan within ten years, another pride of Taiwan. - Exhibitions and Certifications - Tong Ya Electronics began exhibiting in Italy in 2001, gradually stepping onto the international stage, bringing KOSO's dedication and professionalism to the world, and striving to convey an image of high quality and innovation. It obtained TS16949 international certification in 2007, and ISO 14001 and ISO 45001 international certifications in 2024. In the future, it will continue to create more compelling products. Every product launch requires actual installation testing, which is the strictest form of quality inspection. No matter how well a product is designed, its quality is tested once it is actually installed and used. To further improve quality and actual product testing, we participate in international competitions. Every award is an affirmation of our products because they are modifications that do not allow for errors; we are that rigorous about quality. Test reports and product measurement charts are also our demonstration of the results of customer installations. It is because of this caution that our products are able to show better quality time after time. - Equipment and Checkpoints - Our pre-inspection for every product uses the most advanced technical machinery, setting different conditions to simulate and conduct tests, such as vibration tests, waterproof tests, etc. All partner manufacturers who have participated in the inspection process agree with our principles of quality control and trust the test results. It is valuable that as products undergo tests like passing checkpoints, we also add different conditions and make adjustments based on actual environments, combined with user-friendly operation, to present the most realistic tests for products and the improved quality after corrections.

[Pre-order Notice] Before ordering, please double-check the color, size, and other information you wish to purchase. Most products have delivery times provided after the order is placed, so there may be situations where products are discontinued or require a long wait for shipment. If an order cannot be fulfilled due to manufacturer stock shortages or temporary unavailability, it will not be processed; no fees will be charged if the order is not processed. Please understand that manufacturers may unilaterally change specifications or exterior designs, which may result in the packaging or the product itself looking different from the images on the product page. If a manufacturer's unilateral change in product design or specifications prevents the product from performing as expected at the time of order, please consult our customer service for further processing. Products go through multiple shipping processes from order to delivery, so packaging may be deformed or damaged during transit, but the product itself remains intact and usable.

Upon receiving your return request, we will arrange for a logistics provider to collect the goods as soon as possible.
