What we liked
- + Takes USB, optical and coaxial inputs and drives 16 to 200 ohm headphones, with RCA and 3.5mm outputs.
- + Supports 24-bit/192kHz audio with a full metal shell and an output protection circuit.
- + Plug and play with no driver install, and a USB, optical and PC to Type-B cable set is included.
Trade-offs
- - The listing states there is no microphone input, which the original Fulla E offered.
- - Entry-level power and a 3.5mm headphone output limit it for hard-to-drive headphones.
