BT, AK XB10 of high quality

It is now possible to use aptX ™ HD, Qualcomm's latest BT codec, to transmit high-quality (24-bit) data wirelessly, now optimized using Astell & Kern audio technology.

Music via BT without compromise

AK XB10 offers a palpable difference in sound compared to conventional BT products. The moment you hear it, you ask yourself, "Is this sound really coming from Bluetooth?"

Astell & Kern’s exceptional technologies are implemented in aptX ™ HD to support 24bit / 48kHz BT performance, along with the DAC section and built-in amplifier, essential components for quality audio.

Qualcomm® aptX ™ HD

AK XB10 is a device that receives audio data wirelessly from smartphones via BT, and is very different from conventional BT devices, as it supports the aptX ™ HD BT codec.

Just as with television display resolutions that have evolved from high definition standard to 4K ultra-HD for ever better picture quality, we are also in the era where BT supports 24-bit resolutions that can be fully enjoyed with aptX ™ HD.

Typically used in professional broadcasting, the original aptX ™ audio codec is widely used for near-CD-quality 16-bit sound. Advantages of the aptX ™ codec include higher quality compression and low transmission delay.

Launched in early 2016, the latest generation aptX ™ HD codec is capable of transmitting audio up to 24-bit / 48kHz, faithful to the original audio file.

* Devices connected to the AK XB10 must support the aptX ™ and aptX ™ HD codecs for 24-bit audio playback.

SBC versus aptX ™ versus aptX ™ HD

BT codecs can easily be compared with the efficiency of data packets.

By comparing the capacity of data packets in a BT transmission to the passengers of a bus, the SBC codec is able to accommodate only one passenger per bus. The aptX ™ codec seats three passengers, while the aptX ™ HD codec seats five.

Just like the ability to accommodate multiple people on a bus, aptX ™ HD is much more efficient than other audio codecs.

It is in fact possible to transmit more information and data while managing to lose less information.

Perfect sound

AK XB10 is equipped with a Hi-Fi DAC capable of reproducing high quality sound up to 24 bit / 192 kHz. Its analog amplifier was fine-tuned using Astell & Kern sound technologies.

A digital-to-analog converter (DAC) converts digital data into analog signals, and the AK XB10 features a dedicated DAC for error-free conversion that significantly improves signal-to-noise ratio (SNR) and total harmonic distortion (THD) ).

While a typical analog system simply amplifies and outputs low-level audio signals, the Astell & Kern AK XB10 internal amplifier does much more.

Instead of simply amplifying the audio signal, it has been designed with a “driving” concept, so that even high impedance headphones, for which a strong signal is required, can be played. The AK XB10's analog amplifier is more than capable of doing this.

For example: when comparing an amplifier to a camera, comparing the zoom function to magnify small objects in the viewfinder corresponds to the function that a common amplifier does. The one of the AK XB10 is different, it behaves like the panoramic focus function, which clearly focuses on even the smallest details.

Put simply, the Astell & Kern amplifier focuses on every detail, even the smallest.

Double audio output

“Oh no! My headphones are not compatible!

Have you ever seen a tiny headphone jack where regular headphones can't be plugged in?

It is known as a 2.5mm “sub-mini” audio connector, or as balanced. The ways of transmitting an analog signal can be divided into balanced and unbalanced. An unbalanced connection is typically made up of a signal (L + R) and ground. The ground is supposed to prevent external noise, but it can still be introduced into the signal and affect the music, causing level changes and noise.

The balanced connection was developed to reduce ground induced noise. This connection adds a reversed phase signal (-L + -R) to an unbalanced signal (+ L + + R) to decrease the noise.

The balanced connection has several advantages over the unbalanced one. The same noise (common-mode noise) that occurs in the positive pair of a stereo signal (+ L + + R) is found, in the opposite phase (-L + -R) in the other pair of signals, and therefore can be eliminated, resulting in an increase in the total output level, as two separate signals are transmitted.

It was therefore natural for A&K to add a 2.5mm jack on the AK XB10 for audio enthusiasts. Enjoy deeper, more detailed sound through the AK XB10's 2.5mm balanced output.

Compatible with iOS and Android

AK XB10 is compatible with all iOS and Android devices.

XB10 supports SBC, aptX ™ and aptX ™ HD codecs for Android devices and AAC codec for iOS.

Forget about compatibility problems: turn on the BT of your smartphone and connect AK XB10.

You can also connect any laptop / notebook that supports BT.

You will be transported to a new world of sound the moment the AK XB10 is connected to your smartphone.

Hands-free function

When receiving a call while listening to music with the AK XB10, do I have to turn off the BT function before answering?

Is it necessary to disconnect the earphones from the AK XB10 and connect them to the phone?

NO! Of course not!

For maximum convenience, the AK XB10 supports voice calls and is equipped with a built-in microphone, so you can receive calls when using headphones without a microphone.

Press the button once to receive a call while connected via BT and press and hold the button to reject a call. Easy to use.
