We've just received our first shipment of the long awaited Fiio Q5. The Q5 is a DAC and Headphone Amp which includes USB and Bluetooth inputs. We've had a quick play with the Q5 and I am thoroughly impressed.
This device will be perfect for people looking for a headphone amp for devices that don't support USB OTG or prefer to disentangle themselves from the slippery slide of extra dongles and connections. The USB input offers the highest quality and with every device we have tested it has done a thoroughly good job.
This is definitely one to audition if you are looking for a boost to your mobile listening experience.
