alt Hacker News> so shipping with a chunky cable that doesn’t even carry decent data feels like a bizarre oversight.
USB 2.0 can support up to 480 Mbps. It’s more than fast enough for any audio stream you can send to a DAC.
Your headphones don’t need USB 3.0 5 Gbps speeds. USB 3 requires extra wires with different properties that need to be controlled more tightly, which can impact cable flexibility. If your headphones used USB 3 when they didn’t need it that would be one more thing to break and more failure modes for the cable.
A USB 2 cable with fewer conductors was the right choice for this product. The fact that you only got miffed about it when plugging the cable into a tester, not from actually using the product or cable, is good evidence that a USB 3 cable wasn’t needed.
Nobody said the headphones needed USB 3. The point is that the cable is physically thick and rigid (like something you'd expect to carry serious data) but doesn't. Meanwhile Apple ships a thinner, more flexible cable that supports the same USB 2.0 speeds and equivalent power delivery. The cable B&W chose is worse ergonomically for no functional benefit. That's the kind of mismatch the Treedix exposes.
