3.5mm to USB-C Adapter For those of you who find the lack of an audio jack on the newest phones annoying. You can enjoy Hi-Res sound by connecting your phone to wired headphones, headsets, speakers, or even your car stereo using this Type-C to 3.5mm adapter. DAC In comparison to an adapter without a chip, the USB-C to 3.mm audio adapter has better compatibility and can preserve the original stereo sound quality of your headphones thanks to its built-in independent DAC chip, which converts digital audio signals into analog audio signals and achieves up to 95dB noise reduction and 0% frequency range loss. Broad Compatibility Widely compatible with USB-C devices that do not have a 3.5mm port, including the 2018 iPad Pro 11" and 12.9", MacBook Pro 2018/2019, and MacBook Air 2018/2019
