The M11 can be set to Bluetooth Receiver Mode, which allows you to transmit wireless signals through the M11's advanced audio circuitry to provide improved frequency response and to decrease distortion, noise floor, and crosstalk. The incoming signal can even be sent out to external devices via the built-in coaxial output.
FiiO's engineers have incorporated balanced 2.5mm and 4.4mm headphone jacks, as well as your standard 3.5mm single-ended output. With this kind of versatility, you can use your favorite headphones without the need of cumbersome adapters.
The M11 has been outfitted with a large 3800mAh battery that can provide up to 13 hours of continuous playback, and up to 50 days of deep-sleep standby time when not in use. To help alleviate the wait to get back to the music, FiiO incorporated Quick Charge 2.0 and MediaTek Pump Express quick-charging technologies, which allow the M11 to fully recharge in as little as 2.5 hours.
FiiO Link allows you to connect your Bluetooth-compatible Android smartphone with your M11, letting you remotely control the M11 with your phone and display what the M11 is currently playing.
Wirelessly transmit audio through your M11 from your PC or NAS library via DLNA, or from your iOS devices via AirPlay. You can also stream audio right from your computer's browser via Wi-Fi.
The M11 features a 10-band dynamic EQ with the ability to adjust up to plus or minus 12 dB. Built-in presets include pop, blues, classical, jazz, rock, dance, metal, and vocal. You can also dial in your own customized EQ settings to get your audio sounding the way you want it to.
