Its adaptive design allows seamless integration with both iOS and Android devices, offering plug-and-play simplicity. However, while it improves the audio experience significantly, prospective buyers should consider the investment compared to competitors, especially since the Cobalt lacks an internal battery, relying instead on the power from the connected device.
This trade-off results in a slight hit on battery life during extended sessions, though it's mitigated by the improved efficiency of the device. Overall, the DragonFly Cobalt stands out as a premium choice for those seeking high-quality audio enhancement in a portable form.
