Below are excerpts from the review:
We have learnt that the ddHifi MFi09S Lightning to USB-C cable is just one piece in the noise puzzle, sandwiched between a potentially noisy phone and a USB noise filter and a reclocker. That’s when the less imaginative audio linguist pulls out the phrase “your mileage will vary”. It is not a black and white affair. If the signal incoming from the phone is clean (just switch the Wifi and cell connection off), all a poor cable can do is deteriorate the signal, whereas a good cable has a high data integrity.
