Works as expected

I couldn't find an adapter to connect my iPhone to my DAC. This one did it! Haven't had it long enough to know its longevity, but no issues in the first couple weeks

Sturdy and functional

Works great with my USB dac, and just as important, it fits snug in the lightning port unlike some adapters I’ve tried.

An Elegant Solution

This compact ddHiFi adapter allows me to place my iPhone in a belt holster while using a Creative Labs BT-W3. The design and attractive anodized finish is top notch. Audio46 was really helpful and made the entire buying experience very pleasant.
