Many audiophiles who prefer their music on-the-go use their iPhones as their audio content source, connecting their DAC directly to the phone or iPad. The role and quality of the cable are important with noticeable improvements in sound quality when using superior cables.
With ddHiFi’s new Nyx Silver series 2.0 OTG cable, you’ll definitely hear the difference.
The original Nyx MFi09S series used a 1st generation silver shielded wire which used a relatively complex structure of separate shielding for its power supply and data transmission. This greatly helped to reduce noise in devices whose power supplies were susceptible to interference.
The new version 2 Nyx 07 series uses the 2nd generation of silver shielded wire which distributes the power supply and data wires at equal intervals. It also uses imported insulation material with an adjusted-density shielding net with black and white spacing along with an outer insulation layer in accordance with impedance matching. Compared to the 1st gen, the newer 2.0 wire is smaller and more compact.
The narrow-waisted and wide-mouthed plugs are a further extension of the 2023 ddHiFi design language. The advantage of this unique design is to make the plug holdings firmer when plugging in and pulling out. Moreover, the arched-edge will aid in reducing wire creasing, and the bi-color front and rear cavity structure contributes to a more integrated shielding of the plug.
When using an iPhone with audio decoding devices and high current, it’s common to get a pop-up reminder warning that the device cannot be used due to excessive power requirements. The MFi07S uses Lightning 2.0 which allows more audio dongles to be compatible with iPhone.

Excellent quality however when used with my iPhone 12 max when I’m walking over time the length of the lightning connector exerts unwanted leverage force on the connection causing it to come loose. It’s built so strong and a bit oversized that it becomes a serious force multiplier when pressure is exerted on one end. I think this cable is best used for desktop situations where it isn’t being jostled back and forth. In that use case it will probably outlast your phone.
It seems to be built well and has a chance to last longer. I have gone through many dongles that failed after two or three months. So far, its great.
Excellent quality, much more flexibility than expected.
This cable is top notch quality without the sticker shock. Build quality you can feel in your hands. Although I am new to the hi fi audio scene I am glad I chose ddHifi a product as an introduction. Bloom audio has excellent brands at great prices and the customer service is second to none. They really want to help you find what you need and make sure you’re satisfied with your purchase. Shout out to Steven for helping me find a solution that worked for me.
