The FiiO M11S is a portable music player with great Hi-Res sound quality and a wide range of features. The dual DAC design with two ES9038Q2M digital-to-analogue converters ensures pure clear sound with fine detail resolution and vivid playback. The open Android-based operating system allows the use of any apps such as Tidal, Qobuz, Spotify, Apple Music and many more. The Google Play Store is already on the FiiO M11S so that apps can be installed quickly and easily. Audio files and apps can be stored on the 32GB internal memory. The memory can also be optionally expanded with microSD cards via a memory card slot. To ensure that the M11S runs effortlessly, it has been equipped with a particularly powerful processor, an 8-core Snapdragon 660 from Qualcomm. The generous 5-inch touchscreen display clearly shows album covers and is also ideal for watching videos. The M11S can also be used as a USB DAC on a PC for top sound on Windows or Mac computers. The FiiO M11S has a 3.5 mm jack that can be used to connect headphones as well as a line out and even a coaxial output. For connecting balanced headphones and earphones, there is a 2.5 mm jack and a 4.4 mm jack. The latter can also be used as a balanced line out. In addition to WiFi for the use of streaming services, the M11S is equipped with Bluetooth 5.0 for wireless music playback to Bluetooth headphones or speakers. If you want to enjoy music playback in its purest form in between, you can switch off the Android system and listen to a highly authentic, true-to-the-original sound in Pure Music mode.
