Project Name: High-End Earphone

Client Location: Shenzhen

Project Scope: PCB Cloning, BOM Compilation, Reverse Engineering of Schematics, Prototype Purchase of Components, Welding and Debugging

This client found our website online and initially chatted with us via QQ. They mentioned it was about an earphone project, and we didn't pay much attention, assuming it was a simple product that few clients usually pursued. However, when the client brought the physical sample to us, we realized that the earphone was far from being simple. Below is an image of the earphone.

With the BGA, a four-layer board, and the lines and dense feature comparison powerful and cabling requirements. We first carefully removed the components of the board above, and then scan and polished, especially the polished part, we are particularly careful documentation, we have carefully checked, the best welding debugging when debugging or found incomplete functions, followed by turned out to be a transistor purchase wrong. Behind the re-purchase on the transistor, OK, after debugging, we had welded a total of three panels, the back of the test through two, one did not pass, the latter to find the problem turned out to be welded. The last customer to see the prototype of our test, took the documents to produce. Here is introduced the function on the headset:
A main support for Bluetooth and noise reduction. When listening to music, you can press to turn off the music, not take off the headphones and outsiders talk. Next to the person's voice through a microphone to restore release; active noise reduction function is turned on, the outside noise immediately disappear.
Advanced DSP processing technology, to more effectively filter and noise reduction to create a clear call;, built-in EQ equalizer, no matter what the music can make you enjoy the most perfect sound quality performance.
