Review: High Grade Heavenly Hi-Fi Inside and Out! - This is an awesome unit that has a beautiful, pure high-grade sound. The background is clean while the bass is both crisp and full. The treble is well separated from the lows. I did have to set the equalizer master gain slider to its lowest setting to get the output to produce that clean, heavenly sound I was looking for. Before I figured that out, the output was muddy and the bass crapped out even at low volume, but it's all good now! The UI works great and does what you want it to if you are willing to dig through the settings and also learn how Android works. I even got it to add a fire breathing dragon to the boot up cycle (see video). I installed an SSD drive in the backside for storage it works great. The large screen is excellent, and I love being able to see the album cover, track info and stats all on one page. The build quality of this device is top notch! Overall, this is a great piece of hi-fi pre-amp equipment in the $1000 price range for those who already have a dedicated amplifier to plug it into (I am using my FiiO K9 AKM for the amp and XLR/balanced cables between the two devices). I am currently using this setup to run my SONY MDR-Z7M2 Headphones, 1MORE Quad Driver Earbuds and powered Edifier bedroom speakers. All sound high-grade! Excellent addition to my Chi-Fi Tower of Power!
Review: Jack of All Trades, Master of None—Held Back by Poor Execution - After a week of use, I’m updating my review and deducting a point. I wanted to love the FiiO S15—it holds so much promise—but the execution is disappointing. Sound Quality: The Saving Grace Let’s start with what FiiO got right: the sound quality. It’s fantastic and is against my Topping D70 Pro, which is impressive for an all-in-one unit. The S15 also supports visual audio effects like VU meters, which I love—but only when using native apps. If you’re using USB or optical input, forget about it. This is unacceptable for a device at this level, especially when competitors like Eversolo got it right from the start. FiiO needs to fix this. Usability: A Series of Missteps Remote Setup The remote isn’t pre-paired, so you need to dig through settings to get it working. That’s a one-time hassle, but it adds unnecessary complexity. Even after pairing, the remote is not intuitive to use from a distance, defeating its entire purpose. FIIO App does not connect and produces a persistent error. UI Design The UI feels entirely out of place for a device of this size. The S15 is massive and belongs in an entertainment center, yet its fonts and menus seem (android OS) designed for a handheld device. Navigating the interface feels clunky and unintuitive, making everyday use frustrating, particularly from a distance. Cable Management & NVMe Support FiiO’s cable placement is baffling. The USB DAC input—my primary use case is front-facing, making cable management sub-optimal. Meanwhile, the device includes two USB host ports (front and back) and NVMe support (kind of). It only works via a USB-to-NVMe dongle, meaning if you bought an expensive high-speed NVMe drive expecting the fast NVME performance you paid for, you’re out of luck—it’s throttled down to USB speeds via a USB-to-NVME enclosure. Poor design choices like this hurt the overall experience. Final Verdict The FiiO S15 is packed with features, but its execution leaves a lot to be desired. It’s not just a firmware update away from greatness—the design choices don’t make sense. Some of the issues I’ve mentioned are fixable, given how flexible the OS is, but I wouldn’t hold my breath. I’m unwilling to pay for something and cross my fingers that it will get fixed later. As it stands, this unit may need to go back to the sender.

## Features

- The S15 is equipped with an open Android 12 operating system combined with a custom horizontal screen interface, allowing seamless installation and smooth use of major streaming music apps. It also supports Roon Ready, AirPlay, DLNA, and Bluetooth network streaming. Additionally, it is compatible with UPNP, SMB, and WebDAV protocols for playing songs from NAS, local area networks, or cloud servers. Furthermore, it supports direct local playback via built-in storage, TF cards, USB drives, or external hard drives.
- The S15 features the highly acclaimed AKM flagship DAC combination—AK4191+AK4499EX. Utilizing a newly designed fully separated digital/analog architecture, it enhances signal-to-noise ratio and minimizes various noise amplitudes. This design further purifies the background, improves resolution, and delivers sound with balanced dynamics, showcasing a relaxed and natural tonal charm.
- For the first time, FiiO players adopt two industry-renowned ACCUSILICON AS318-B series ultra-low phase noise femtosecond oscillators (45.1584MHz and 49.1520MHz), which undergo 100% selection to effectively reduce the impact of phase noise on audio signals. This ensures exceptionally high fidelity in decoding and unparalleled precision in digital output. When paired with power amplifiers or external DACs, the player delivers reference-grade sound performance.
- The S15 is equipped with a comprehensive array of digital and analog interfaces, including the newly added I2S output, AES input/output, coaxial input/output, HDMI input/output/ARC, RCA line output, optical input/output, and XLR balanced line output. With its standard chassis width of 430mm, the S15 seamlessly integrates with larger desktop audio systems, ensuring a more coordinated and aesthetically pleasing setup.
- With a 7.84-inch automotive-grade large color display and the new FiiO OS, the S15 showcases excellent adaptability across various usage scenarios. It supports local operation through dual knobs and dual virtual buttons, Bluetooth remote control, and app-based remote control, offering a versatile and user-friendly experience.

### ⭐⭐⭐⭐⭐ Great sound quality!
*by S***P on June 22, 2026*

Man this thing really sounds good! I have owned almost every Fiio DAP, so the functionality of the Fiio app in the S15 is the same. I can see how it may take a little time to figure it out if this is your first exposure to Fiio, because the owners manual is a little sparse. Once up and running, I’ve had no issues. Love it!
