The FiiO Q7 is a high-performance headphone amplifier with DAC and can be used both portable (with built-in rechargeable battery) and stationary (with supplied power supply). The FiiO Q7 implements the highest quality components: a flagship ES9038Pro digital-to-analogue converter from Sabre, THX AA788+ high-end desktop quality amplifier circuitry, an XMOS XU316 16-core USB chip and a QCC5124 Bluetooth chipset from Qualcomm. This enables the FiiO Q7 to deliver performance and sound quality at the highest level. Thanks to its diverse connectivity options, the FiiO Q7 is versatile: For example, you can use the Q7 to play music from your computer on your stereo system at home or to listen to music from a smartphone on the go with headphones. The connection can be made either by cable coaxial, optical or via USB as well as wirelessly via Bluetooth. When using Bluetooth, the DAC of the iPhone/smartphone is bypassed and the signal is converted by the flagship DAC of the FiiO Q7. This results in wonderfully detailed lifelike sound even when streaming via Bluetooth. Since the power supply plays a decisive role in the sound, a dual power supply system has been implemented in the FiiO Q7. So on the one hand, the Q7 can be used portably via the integrated battery and you get a whopping 1500 mW of power. If you want even more output power, you can plug the Q7 into the mains and it will deliver a massive 3000 mW of power. With the FiiO Q7, you get more power and high-end sound out of your player - whether you're at home or on the go. For easy operation, there are buttons and a volume dial on the housing, and the colour display shows all important information clearly.
