The QCY brand was founded in 2009, with the core product concept of "Pleasure in it", aiming to create comfortable and trendy wireless products, where Q stands for Quality, C stands for Creative creation, and Y stands for Young. Its head office, Hele Electronics, provides foundry services for Xiaomi True Wireless Headphones.

The price of QCY products is concentrated within 200 yuan, and the hardware configuration of the products is similar. It has achieved good reputation and sales with higher cost performance: like the QCY T5S true wireless Bluetooth headset and QCY T5 true that I have disassembled before. The wireless bluetooth headset and QCY T4 TWS true wireless bluetooth headset are basically this upgrade idea, with distinctions in appearance, wireless charging function, internal components and software functions.

Today we are going to disassemble the QCY T6 true wireless sports earphones, which come with silicone anti-slip earhooks, suitable for sports wear; the earphones newly use a 12mm large-size dynamic unit, and other hardware configurations are basically the same as T5S, such as a built-in charging box 600mAh large-capacity battery; the headset uses the original Bluetooth 5.0 chip, supports low-latency game mode, supports touch, supports call noise reduction, IPX5 waterproof, etc.; Android phones can download APP to unlock more settings. Let's take a look at the internal changes through disassembly~

I have also disassembled QCY T1S TWS Bluetooth headset (wireless charging version), QCY T1 youth version true wireless Bluetooth headset, QCY Q29 TWS true wireless Bluetooth headset, QCY-L2 active noise reduction wireless neck headset.
