Samsung’s flagship products are usually very good at media playback, and with the introduction of the new Galaxy S9 series, the situation is even better, because both phones have AKG-tuned stereo speakers. The main speaker is located at the bottom and emits outwards, while the second speaker is actually a headset and is also used when playing media files. It’s not that loud, and the speakers on the bottom are obviously more powerful. However, this is still better than using mono audio from only one side of the phone. There is a Dolby Atmos toggle in the Settings app that slightly increases the treble and midrange frequencies, making the sound more crisp. Samsung claims to have a 3D surround sound experience on the Galaxy S9 Duo, but in our tests we did not find the surround sound effect to be very noticeable. Like the previous generation headphones, the bundled headphones are also tuned by AKG, which provide balanced sound and good passive noise cancellation.
