Product Description

Grassot copper sound unit

Liquid crystal polymer thin film diaphragm, high standard disphragm and light weight drive unit can deliver the vigorous strong bass and elongated treble, use the Imported neodymium boron, High performance magnetic circuit system design, Collocation's tone chamber design allows you to feel the original sound field.                              
                                        

Real noise reduction headphones

After 360 degree full range accurate pickup of environmental noise, by fully enclosed double loop noise reduction guide chip, and advanced algorithms for analysis and processing, the product can reduce low frequency noise of 50-500HZ up to by 16-20DB, especially good for optimized noise reduction and debugging for airplane engine noise.

The wireless Bluetooth headset is foldable noise reduction headphones

portable which lets you fold it into a compact bundle for storage or take it with you when travellingt. Configuration of exclusive noise reduction circuit, including customed high sensitive microphone and professonal noise reduction chip, by receiving and analyzing the outside noise spectrum, producing the opposite phase of the signal to counteract it, so as to achieve the purpose of shielding the external noise, then give users a comfortable and quiet private space.
