Use Wirelessly with Bluetooth
I tend to describe Bluetooth audio as wireless freedom with fewer strings attached — literally. When you see Use Wirelessly with Bluetooth, it means you can pair your headphones or IEMs with phones, laptops, or even TVs — all without reaching for a cable 🎶. It’s convenient, clutter-free, and great for everyday listening.
What’s happening behind the scenes is your gear is using Bluetooth codecs like SBC, AAC, LDAC, or aptX to compress and transmit your music wirelessly. Better codecs mean higher quality and lower latency. Of course, there’s a trade-off — Bluetooth won’t match the quality of wired gear, but today’s advancements have made the gap much smaller than before.
When you see '✂️ Use Wirelessly with Bluetooth' products, expect: tangle-free convenience and solid sound quality — great for commuting, workouts, or casual listening.
Battery Life
In my experience, battery life is one of those things that separates a good day from a frustrating one. It's like having a fuel gauge you can rely on — longer battery life means less charging and more uninterrupted music. Whether you're on a flight or just commuting across town, this is one spec you don’t want to overlook 🔋.
Technically, battery life refers to the hours your device can play music on a single charge. Today’s headphones and DACs can range from 4 to 40+ hours, depending on things like Bluetooth codec, volume, and active features like ANC. More battery life also means better travel and portability, though it might come at the cost of size or weight.
When you see '⏳ Battery Life' products, expect: longer listening sessions, fewer charging breaks, and stress-free portability for music that goes the distance.
Battery Capacity
I usually think of battery capacity like the size of your water tank — it determines how long the tap can run before drying up. In audio gear, higher capacity means more playtime, more power for your amp section, and better performance during high-demand usage 🧠. It’s especially important if your gear also powers powerful drivers or amps.
Measured in mAh (milliamp-hours), battery capacity helps you gauge how long your headphones, DAC, or amplifier will last between charges. Devices with higher capacity (like 3500mAh+) are ideal for extended use or when you’re away from a power source. Just know, larger capacity often means longer charging time and a slightly bulkier design.
When you see '🔋 Battery Capacity' products, expect: more power and longer playtimes — ideal for travel, long workdays, or heavy use without worrying about recharging.
Connect With Cable
In my experience, there’s still nothing like the dependability of a wired connection when it comes to audio 🎧. I love describing it as the direct flight of music — no delays, no turbulence. When a product says “Connect with Cable,” it means you’re getting the most reliable signal path, with zero wireless compression and minimal interference.
Here’s what’s actually happening: a physical cable transmits uncompressed analog or digital signals directly from your source to your gear. This results in lower latency, no signal drops, and consistently better sound — especially when paired with a good DAC or amp. It’s ideal for critical listening, gaming, and professional use. The trade-off? You’re tethered — but for a lot of audiophiles, that’s a small price to pay for sonic purity.
When you see '🔗 Connect With Cable' products, expect: pure, uninterrupted sound quality that lets your gear perform at its full potential — perfect for focused, high-fidelity listening.
Why it Sounds Amazing
DAC Chip
I like to say the DAC chip is the heart of any audio device — it’s the part that actually transforms digital files into music you can hear 🎧. Think of it like a chef decoding a recipe to create a delicious meal. The better the DAC chip, the more faithfully it translates your music. And in my experience, a great DAC can completely change how your headphones sound.
Now, here’s what’s actually happening: a Digital-to-Analog Converter (DAC) takes digital signals (your MP3s, FLACs, or streams) and converts them into an analog waveform your ears can enjoy. Different DAC chips — like those from ESS, AKM, or Cirrus Logic — offer their own sound signatures, levels of clarity, and noise performance. A good DAC ensures accurate timing, minimal distortion, and exceptional resolution.
When you see '⚙️ DAC Chip' products, expect: clean, detailed audio and better synergy with high-quality headphones — perfect for anyone upgrading from average sound to audiophile quality.
Power Output
I like to think of power output in audio gear like engine horsepower, it determines how much muscle your setup really has 💪. Whether you’re trying to drive a pair of power-hungry planar headphones or just want headroom for dynamic peaks, power output is the spec you want to check first.
Technically, it refers to the amount of electrical power (measured in mW or Watts) an amp or DAC/Amp combo can deliver to your headphones. More power means better control, improved dynamics, and the ability to handle demanding gear without distortion. But more isn’t always better, too much power with sensitive IEMs can introduce hiss or harshness.
When you see '🚀 Power Output' products, expect: strong driving capability, better dynamics, and optimal performance with headphones that need serious juice to shine.
Balanced Output
I often say balanced output is like using both hands to carry something heavy — it distributes power evenly and keeps things stable. In audio gear, balanced output helps reduce unwanted noise and interference, especially over longer cables. Think of it as a cleaner, more efficient way to transmit your music, ideal for anyone using high-end DACs, amps, or studio-grade headphones 🎧. You’ll typically find it on gear with XLR or 4.4mm connectors, and it's a must-have if you’re chasing that ultra-clean signal path.
Here’s what’s actually happening: a balanced output uses two separate signals, one inverted, so when interference is picked up along the cable, it gets cancelled out when the signals are recombined. The result? Cleaner audio, better dynamic range, and more power output — especially when paired with balanced headphones. The trade-off? You’ll need gear that supports balanced connections on both ends to really enjoy the benefits.
When you see '⚖️ Balanced Output' products, expect: ultra-low noise, more headroom, and better synergy with high-impedance headphones or sensitive IEMs — ideal for serious listening setups.

Additionally, the Q15's coaxial input allows direct connection to digital streamers and CD players, eliminating potential losses associated with indirect connectivity issues.


EXCLUSIVE PHONE MODE OPERATION AND BUILT-IN COMPREHENSIVE PROTECTION MECHANISM
The FiiO Q15 features an exclusive phone mode, easily activated through a standard switch on the device's back. In this mode, the Q15 operates solely on its battery, preserving the smartphone's battery life. This feature ensures prolonged performance and battery longevity for your smartphone. FiiO's engineering incorporates multiple hardware and software protection measures for worry-free sound enjoyment. These include a maximum volume limit to prevent hearing damage, a high-temperature-resistant battery with temperature-based charging control for extended durability, and protection mechanisms against over-heating, over-voltage, and DC issues, ensuring stable power output and headphone safety.
NOTE: If you need to connect to a computer, turn off Phone Mode.


FREEDOM TO CUSTOMISE YOUR SOUND THE WAY YOU WANT WITH A BUILT-IN GLOBAL PEQ
The FiiO Q15 is equipped with seven EQ presets and three customisable PEQ presets that can be applied in both Bluetooth and USB DAC modes. FiiO's self-developed PEQ algorithm and a user-friendly interface allow you to precisely adjust frequencies, gain levels, and bandwidth, enabling fine-tuning for your preferred sound profile. Customisable PEQ, including support for coaxial input, will be available through future firmware updates. USB DAC PEQ supports 192kHz/24bit PCM, with EQ management handled by the XMOS chip. When toggling EQ on and off in USB DAC mode, the USB connection briefly disconnects and automatically reconnects, and tapping "play" restores the output. Furthermore, experience subtle changes in the sound with 7 built-in filters.


15-WAY DIGITAL-ANALOG POWER SUPPLY FUSED WITH HIGH-QUALITY COMPONENTS FOR CLEAN SOUND
Within the FiiO Q15, a sophisticated 15-way digital-analog power supply is incorporated, encompassing systems for the digital segment, analog segment, and headphone amplifiers. The precise regulation involves 21 low-noise LDOS and an ample energy reservoir with 35 low-resistance tantalum capacitors. To minimise crosstalk and shield against external interference, the audio circuit segregates the digital and analog components. FiiO's meticulous selection includes 60 1% precision, low-temperature drift resistors, and 28 wide temperature range NPO capacitors, ensuring the Q15 faithfully reproduces high-quality audio with unparalleled fidelity even in challenging conditions.



PORTABLE DESKTOP-GRADE PERFORMANCE WITH FULL-COLOUR IPS DISPLAY AND VOLUME KNOB
The FiiO Q15 introduces a novel desktop mode, accompanied by a dedicated Type-C power connector. When connected to the PD power adapter, this configuration enables external power, completely bypassing the battery and providing a desktop-like experience on the go. Additionally, the Q15 boasts a 1.3-inch full-colour IPS display, offering a clear view of vital information like working mode, sampling rate, volume level, battery status, gain, and more. The display adapts seamlessly to changes in orientation, ensuring optimal functionality. You can choose when the screen goes to sleep, helping to save power according to your usage habits. Coupled with the versatile volume knob, users can swiftly and accurately perform various functions, including volume adjustment, input switching, and menu settings.


EXPERTLY DESIGNED AND ENGINEERED WITH APP SUPPORT AND AVAILABLE IN TWO COLOURS
The FiiO Q15 introduces AG glass on its back panel, providing anti-scratch and anti-fingerprint properties with a refined touch. Its golden size ratio of 18:9 ensures comfortable handling, whether used on its own or alongside other portable devices. Whether you're on the go or a business trip, maintaining control over your high-quality sound is effortless. The FiiO Control App (for Android, for iOS) facilitates easy management and adjustment of functions. The Q15 is offered in two colours, Black and Titanium Grey, providing options to suit your preference.
