Your iPhone, iPod, MP3 players, phone, tablet, or any other device with a 3.5mm aux port can be connected to your headphone, earphone, speaker, car stereo, and more with the UGREEN headphone extension cable. Important Information: The audio will function if you use TRRS headphones with this cable, but the microphone won't shield your aux port. An excellent way to shield your 3.5mm port from frequent plugging and unplugging is with a UGREEN 3.5mm extension cable. Purchasing a new gadget is expensive, but obtaining an aux extension cable is very simple. Amazing Audio Quality: Shielded 3.5mm audio cable extension with double shielding and 24K gold-plated corrosion-resistant connectors offers the best signal transmission and crystal-clear audio.
