2.5mm
Balanced Output
Multi-point Connection
Bluetooth multipoint technology was introduced with the release of Bluetooth 4.0, over a decade ago. It’s a feature that allows Amps & DACs to maintain simultaneous connections to at least two source devices like a laptop and smartphone.
Multipoint allows you to seamlessly switch between devices, such as a computer and phone, without touching your devices. Multipoint technology is a great asset to increase productivity and convenience as you go through your daily life - from home to work. The simultaneous playback of audio from two devices is not possible with Multipoint, though.
In simple terms, Multipoint enables you to maintain a connection to two of your favourite, often-used devices at the same time. It is a great functionality allowing you to multitask without the hassle of tweaking the settings of Bluetooth.
DAC Chip
You may not even realise it, but most of us use a digital-to-analogue converter (commonly known as a DAC) daily. Built into your computers, tablets and smartphones, a DAC is fundamental to unlocking the convenience of digital music. Any device that acts as a digital sound source will need a DAC to convert digital audio to analog. A DAC converts the digital information stored in “0s and 1s” into an analog signal that's passed to speakers or headphones and ultimately our ear. In short, DACs play a large part in making digital music hearable.While this technical process is undoubtedly impressive, the DAC embedded into your smartphones or laptops is nowhere good enough to listen to your favourite music recordings in high quality. So, if you want to listen to music in high quality, an external DAC is essential to allow headphones or speakers to perform at their potential. An external DAC, first and foremost, will improve audio quality dramatically.
Upto 1.8Vrms
Power Output
Battery Capacity of
350 mAh
For an Audiophile looking to listen to music on the go with the convenience of their mobile phones, this is an absolutely priceless DAC. For me, the 2.5mm balanced output is what makes this a serious audiophile essential you can't go wrong with.

DESCRIPTION
A DEDICATED DAC/AMP THAT OFFERS 2 AUDIO OUTPUTS
The XB10 features a dedicated DAC that has been tuned using Astell&Kern's latest technologies. The amplifier drives just about any headphone while amplifying even the minutest of details. A standard-sized 3.5mm jack provides connectivity to maximum devices. The 2.5mm jack, on the other hand, is for those audio enthusiasts who are looking to enjoy a deeper level of sound. It eliminates ground noise and provides a balanced connection resulting in increased output.

STREAM HIGH-QUALITY SOUND WIRELESSLY
The Astell&Kern XB10 is very flexible in terms of connectivity. It supports SBC, aptX™ and aptX™ HD codecs for Android devices and the AAC codec for iOS. Just turn on your smartphone, tablet or laptop's Bluetooth and you're good to go. Qualcomm aptX™ HD technology is capable of transmitting up to 24-bit/48 kHz audio that is faithful to the original audio file.




TAKE CALLS WITH EASE
The XB10 is a game-changer providing solutions to all your problems. Along with high-quality music, it also lets you answer calls without having to access your phone. Answering/Declining calls just requires the tap of a button while the inbuilt mic makes for crystal-clear calls.




CARRY IT ANYWHERE

Want to carry your music along? Simply clip the device to your shirt or bag and run along. The clip keeps your hands free and lets you flaunt Astell&Kern's classy light and shadow design.
