One for all - the FiiO M9 is a music player with many applications and is very simple and practical to use. Music files can be stored on the internal memory or on an optional MicroSD card, allowing you to enjoy your music in excellent audio quality. It supports all common lossless audio formats for a full-range music playback experience. If your personal music collection becomes too small, you can use a streaming service like Tidal, Qobuz, or Spotify via WiFi, which offers a vast selection of music and audiobook titles. The FiiO M9 works well with almost all headphones and earphones between 16 and 300 Ohms with a 3.5 mm standard or 2.5 mm balanced connection. For those who prefer wireless, the FiiO M9 can be connected to a Bluetooth headphone or a Bluetooth speaker. It also performs well with a laptop or PC when connected to a USB port, enhancing sound quality as an external sound card.

The two AK4490EN DACs provide a precise, natural sound signature with plenty of dynamics. Even when using Bluetooth, excellent sound quality is ensured: the FiiO M9 supports high-resolution Bluetooth codecs aptX HD and LDAC. The operating system of the FiiO M9 is based on Android and has been optimized by FiiO for music playback. The operation is correspondingly simple and is done via the touchscreen or the buttons on the side of the FiiO M9. The housing of the FiiO M9 is made entirely of aluminum, giving it a premium look and making it very durable.
