Fiio X5 III, new portable audio player.

X5 3rd gen
Portable player without loss and mastering quality, based on Android

Sound quality, double or nothing

Dual DAC for silky smooth sound
The X5 3rd gen comes equipped with two excellent AKM AK4490ENs, one for each channel. The AK4490EN is part of a new generation of high-quality 32-bit DACs that support PCM and DSD formats. Thanks to the dual-channel implementation of AKM’s low-distortion VELVET SOUND architecture that includes digital filtering with 32-bit processing, the X5 3rd gen DAC chips have the ability to reproduce music with complete accuracy.

Double crystal oscillator for faithful music reproduction
The X5 3rd gen employs two independent crystal oscillators – one for DSD/ 44.1/ 88.2/ 176.4/ 352.8 sampling rates and the other for 48/ 96/ 192/ 384 kHz. This ensures that, at all sampling rates, jitter is significantly reduced, clock accuracy is improved, performance is more stable, and there are virtually no artifacts in sample rate conversion.

Four-way LPF for first-class amplification
The 3rd gen ) and a greater ability to manage capacitive loads. The outstanding sound quality of the final sound architecture used in this model is the result of having beta users very close to us working tirelessly with the FiiO team in the quest to improve this new X5 sound to the maximum.

Two headphone outputs for double the fun
The X5 3rd gen model has two headphone outputs – one RCA and one balanced. This allows the new X5 to cater to supporters of either type of headphone output.

Highly customized Android 5.1 operating service for more efficient music playback
To solve the problem of third-party Android apps automatically converting the music sampling rate, the FiiO software team developed a completely new audio architecture for its own version of the Android 5.1 operating system. . The result is improved sound quality and better overall device performance and also gives you 90 minutes more battery life compared to running Android 4.4.

Two operating modes for greater satisfaction
The X5 3rd gen, following in the footsteps of the best FiiO player, also offers two operating modes: Pure Music mode and Android mode. In Pure Music mode, you can only access the main music player – no other music player apps can be accessed for smoother operation and better sound. In Android mode, the user can install and use other Android applications, according to their needs. By offering these two modes, the X5 3rd gen can satisfy the most purist users and those who require greater versatility.

WiFi and Bluetooth (aptX) for the connected era
The X5 3rd gen introduces a number of new features for wireless connection – 2.4 GHz WiFi allows users to listen to their favorite online streaming services; aptX enables the highest quality wireless Bluetooth connection; and DLNA offers more ways to connect wirelessly. With the X5 3rd gen model, you can listen to music anytime, anywhere.

New user interface, completely revised
The X5 3rd gen model features a new user interface, reshaped down to the last pixel – for example, many of the icons have been redesigned, such as those for equalization and system settings. The new interface has a black cover, with very well thought out touches of color so that the presentation is clean and modern.

Hidden Micro SD cards
To make the chassis more modern and durable, the X5 3rd gen design team had to reconsider the design of the Micro SD card slots. In this new design made of elegant stainless steel powder based on new metallurgical methods, the separation between the micro SD slot and the rest of the chassis is only 0.2 mm, making the design even more attractive.

Two micro SD card slots
The X5 3rd gen has 32GB of internal storage and two external micro SD card slots. Since each slot allows the insertion of a 256GB card, the X5 3rd gen is capable of storing a staggering 544GB of music – enough to store up to 130,000 songs.

Side volume button
New to the X5 3rd gen is the side volume button, slightly hidden within the protection to prevent the volume from being accidentally raised or lowered, but still comfortable to manipulate. The volume button contains several characteristic FiiO design features, such as 45º grooves or rigid lines and soft circular elements that complement each other to achieve a surprising and unique look.

Two charging modes to get up and running quickly
The X5 3rd gen incorporates a 3.8mV 3400MAh battery that provides more than 10 hours of playback. But when it runs out, the new . When charged at the maximum current rate of 1.2V, the X5’s battery can be charged in just an hour and a half.

Meticulously detailed, inside and out
The improvement in the feel and grip of the body of the X5 3rd gen compared to the previous X5 is evident. To achieve a smoother finish, the body of the X5 3rd gen is made of specially selected No. 180 zirconium sand. The front panel features a subtle dot matrix pattern, while the back is elegantly adorned with an attractive star pattern. Anodized titanium and gold paint harmonize perfectly with each other, giving the X5 3rd gen a luxurious but restrained look. The molded plastic chassis and stainless steel corners come together seamlessly on the new X5, creating a very clean look. With this, even the headphone jack is more durable and integrates better into the rest of the body.

A very versatile player
The X5 3rd gen can be used in various ways according to the user’s needs. With a special cable, the X5 3rd gen can be used in the car thanks to its In-Vehicle mode. It can be connected to a computer as a USB DAC. It can also act as a transport, outputting digital audio signals to an external USB DAC. And finally, it can also connect to a FiiO K5 charging base, through which it can be charged and connected in various ways.

Practical but beautiful accessories
Available for the X5 3rd gen screen we have a 7H tempered glass screen protector, which is hard enough to resist most scratches, but allows approximately 90% of light to pass through, so you will be able to look at the screen comfortably for many years. years. We also offer leather and polyurethane cases for the new X5, which will not only protect your valuable investment, but will make it easier to use thanks to a more comfortable grip.
