For K240 K141 K271 K702 Q701 K712 Headphone Cable Mini Cartoon Head Upgrade Line 1. Twisted pair: twisting the hot and cold signal wires against each other can offset the magnetic flux caused by the current and reduce the signal transmission loss. At the same time, the effect of current noise caused by the external magnetic flux passing through the connection line can be reduced. Therefore, high-resolution sound with a sense of presence can be realized 2. Multi-gauge conductor: Using multi-gauge strands on the same wire can minimize and control the transmission loss in each power range. Realizes high transparency and clear sound from low frequency to high frequency 3. Pure copper OFC: Using a 2-layer conductor composed of pure copper OFC (oxygen-free copper), it can minimize signal transmission loss and distortion, and reproduce treble frequencies smoothly 4. LR independent grounding: Independently grounded 4-conductor structure can obtain a wide sense of acoustic space and tight bass, and improve the separation of left and right channels 5. The effect of the cable on the sound quality: From the perspective of fidelity, the audio signal passing through the cable should be exactly the same as the input signal, and the audio signal transmission will be different due to the purity of the cable, which will affect the change of the sound quality. 6. Wire core: OFC copper wire has good electrical conductivity, bright and shiny surface, and the silver layer has high corrosion resistance 7. It can improve the resolution and separation of the earphones, eliminate the feeling of the dull bass of the earphones, and make the sound more transparent, natural and beautiful 8. 3MM thick multi-core wire diameter, super strong 9. Applicable products: The playback audio source interface is the national standard 3.5mm, which can be compatible with mainstream equipment in the market 10. Wire diameter: outer diameter about 3.0mm 11. Product plug: 3.5MM stereo distribution with 6.35MM conversion head 12. Applicable models: suitabl
