However, to use it with iOS devices, you'll need an additional Apple Lightning-to-USB adaptor, and similarly, an adaptor is required for Android devices, which might be a slight inconvenience for some users. Despite its small size (57mm x 19mm x 12mm) and light weight (4.2 ounces), it features a robust build, ensuring durability. Connectivity is straightforward with its USB Type A connector, but it's worth noting that it's a wired device, which may not be as convenient for users who prefer wireless solutions.

The Dragonfly Cobalt is powered directly from the connected device, so there's no need for an external power source, which enhances its portability.
