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.

Good...but my review please ':)

Update : I like to mention a serious issue about this product, it's bluetooth range is very poor like you if u r in a 100 sq feet room, if u move out more than 4 to 6 foots
It's lost the signal

Go 4 bundle offer then only it's worth for the money u pay

First of all thanks to headphone zone team , they doing excellent service for Indian audiophiles

Though am not an audiophile, Beginner

Speakers we can't enjoy anytime , but earphones/headphones is a personal thing
My first perfect purchase was audio technica m40x , that's 2017 from Flipkart at that time I don't know about HPZ guys
And just 2 months back bought Fiio FD1 from Amazon

I was pretty happy with m40x & fiio k1 dac
For all these 4 yrs, somewhat I planned to buy a Bluetooth DAC for convenience, though I strongly believe nothing can't compare with WIRED quality
Amazon , Flipkart search didn't fulfilled my Bluetooth DAC purchase , they just having that fiio btr.u & fiio btr5 one is priced 2300 that reviews said they are very average & btr5 got better reviews but it's 9k , am not ready to invest 9k for BT, cuz I believe BT is convenience only ..
At this time Google intro me about HPZ :)
After entering in to this site, I was just like...OMG...I entered a treasure hunt zone :)
Too many brands , too much options
Bought these Ak xb10 after read users
& expert reviews , which is almost flawless
So I bought these

Iam happy with the sound output...
but but but
they claimed 5 hrs battery life actually it's 3 hrs only if Ur volume is about 75%

And the worst part is for these 3 hrs we have to charge this for 2 full hrs (5v 2A)..phew this is really tough nowadays , cuz we using mobile phones with 5000mah battery charged in 30 always with my Mi powerbank ,like iPhone users :)

And the charging port is micro USB, thank God my Jiio WiFi had this :)so using that

Experiencing all these , read lot of reviews I feel I would purchase fiio btr5 or shanling Up4 writing these review after 10 days of my usage

So if Ur priority is BT DAC just spend some more and go 4 fiio btr5 or shanling Up4

Also I like to mention...don't compare WIRED & BT ...this AK xb10 BT sounds just slightly better than Fiio K1 dac ..(it's jus 3k), if anyone priority is quality alone , they should opt for wired.
That's why
In just 10 days I made another purchase , hopefully I'll receive shanling ua2 by today, HPZ tempting like anything :) will update the review soon for that

Once again thanks HPZ team, and the playlist cards are just amazing, keep rocking our ears :)

P s request : please try to provide us JADE AUDIO products

This little powerhouse is a beast!

Getting right down to the meat of it, this little device has so much to offer than what just meets the eye.
1. Gorgeous upgrade sound quality ( I use the AK Billie Jeans)
2. Good portability, and it comes with a neat little clip. And the way in which it is designed allows it to stay put in one place despite rough use with NO rattling to speak of
3. It has a "button locking mechanism" neatly integrated with the power button to prevent accidental key activation

These design consideration make this devices' worth seems more than the value asked for.

Just go for it!

After lots of mixed reviews on YouTube. I still went with the AK XB10 as they were on discount (thanks Headphone Zone) and this was one of my best investment in my audiophile collection.

The size is really compact.
It has Play pause, volume Up/Down and bluetooth controls on top.
You have 2 buttons for changing track, micro USB for charging and power on/off controls on the side.
It comes with the mounting clip as well.

Im using this with v-Moda Forza metallo which is suggested by Headphone Zone. The combination works extremely well. This pair has become my go to gear for audio listening. I have tried this with other headphones too and the sound is really crisp. The bass is punchy and sound is extremely clear. You also have an option to enable and disable DTC I usually keep this in and yes it does make a difference.

I have had my issues with Headphone Zone but I have to say. Thank you for your recommendation and amazing prising. I would never have bought them blindly on the full prise, but discounts makes experiments possible. And ofcourse your recommendation never fails. Super Happy!!!

Additionally, I also received Genre based Audiophile playlist cards which can be scanned on Spotify which was super awesome.

So glad to know that you love them:) We look forward to serving you again. Happy listening!
