In addition, its rechargeable battery offers up to 13 hours of autonomy to enjoy music all day.

The Fiio Q11 is a versatile model that can decode and amplify all your music. To do this, the Fiio Q11 portable headphone amp incorporates a CS43198 DAC coupled with crystal oscillators to ensure accurate conversion and limit jitter. This DAC then ensures optimal support of the majority of formats up to a very high resolution of 32 bits / 384 kHz, as well as DSD files up to DSD 256.

The DAC of the Fiio Q11 portable headphone amplifier is combined with very low-noise components and high-quality amplification. It offers extremely low distortion and wide frequency response to reproduce the full richness of Hi-Res tracks. It can deliver up to 650 mW under 32 ohms on the balanced 4.4 mm jack output or 165 mW under 32 ohms on the unbalanced 3.5 mm mini-jack output. Enough to ensure the good supply of the majority of headphones and earphones. The 3.5 mm mini-jack output of this portable headphone amplifier can also be used as a coaxial output to connect an external DAC.
