AudioQuest DragonFly Cobalt
The DragonFly Cobalt is AudioQuest’s newest USB DAC. It comes with a USB-C adapter so it’ll work well with Apple’s newest notebooks which only have USB-C ports. It features an ESS ES9038Q2M DAC chip and supports playback up to 24-bit/96kHz. Its 3.5mm output provides 2.1 volts of drive which is sufficient for all but the most powerhungry headphones. You could also connect it to an amplifier or powered speakers.
