Wireless Freedom With aptX HD

We’d all like to improve the sound quality coming from our smartphones, but with traditional portable DAC/amps come additional cables that get in the way. Not so with the Astell&Kern XB10: a small circular device that wirelessly transmits audio data from your smartphone via Bluetooth. This DAC/amp supports the Qualcomm aptX HD Bluetooth codec, allowing for high-resolution 24-bit/48-kHz audio that’s faithful to the original file. Compatible with Android, iOS, and many other Bluetooth devices, the XB10 boasts both a standard 3.5-millimeter output and a balanced 2.5-millimeter TRRS output. It's especially great for newer iPhones without a 3.5-millimeter jack, as it can bypass the need for a dongle. It has a built-in microphone for hands-free calls, and comes with a clip for convenient attachment to your clothing.

Driving High-Impedance Headphones

Rather than simply amplifying the audio signal, the amplifier was designed with a "driving" concept to amplify weak signals and power difficult-to-drive high-impedance headphones. A strong signal is required to drive headphones with a high impedance. The XB10’s analog amplifier is more than capable of handling the task.

Sorry but my phone decides the spelling.It makes a mockery of its life's work of proper spelling.My review gets distorted by all of the above.The Xb10 lives in a land of its very own where a very small bit of black plastic is so powerful that it's 1 oz weight shouldn't even drive any but the low hanging devices with virtualy no impedance yet this one drives bones that prompts the owner to buy some high cost Dragon slayer amp to do what an Xb10 somehow defies the visual it has and it is tuned by the engineers at Astell who have such high standards that if they dare give the market anything less than a mind blowing ride and makes all they come out a best in class-a class of their own.When hearing the unmistakeable Ak sound pouring out of this little near invisible dac amp and are stunned by the apt x codec that makes this blue tooth device sound as good as virtually all other wired alternatives-more often way better-you just know that this little thing makes a mockery of what is seemingly near impossible to a forever sense of awe that you must give in to it and know that anything named Xb and then 10 is. a name suitable to rocket ships that make their living putting out such overwhelming power and gets super sonic in seconds and blows straight through all forces he'll bent on taming all comers.This is a rocket ship for all items that will and does blow past virtually all others and does so with style and finesse though capable to blow out an eardrum if you wish it to be such a brute.Also phone calls are are crystal clear and the the easily mastered way it does it inspires a quick confidence.It immediately was a go to amp without peer and may always remain in that spot for reasons that defy and blow past any reasoned logic and designed to watch you watching it and be no less than an unlikely very elegant bunch of power wither finesse of a thoroughbred always on call to do the job of pushing the envelope with uncanny style grace and a visual unlike any other now as well as back to 2016 and we'll beyond 2026.
Ok Drop asked me to write about the Ak Xb10.Its always been amazing and as usual Ak comes up with a hyper cool featherweigjt(about 1 oz) black orb rhat unlike Ak players feels like it could break anytime.Ive had the same one since they were over $200 at launch.Its a black amazingly well designed apt x rrady dac,powe4ing all iems to very high clear crisp volumes and having used it woth only Ak120ii and all the other Ak70's etc makes the Ak player even better which is a bit unusual(very unusual for almost any amp especially this one from way back in time.I have no need for any otjer amp when this very small black flying saucer can and does fit into and can if youre not aware dissapear because its black ,very small and even though it obviuosly is jam packed with all needed features-no gimmicks and almost immediately you intuitively know all about it.Anyway $50 is a tiny price for what amounts to a wonderfully even now fururistic amp +++ that even has a balanced option rhat actually makes hearing rhis rhing run wirh most any wored,much bigger gear on the same level as an ea4 studio which is the only one rhat i would now buy if all now 3 Xb10's deacided ro dly off and go inter galactic ro be a good ambassodor and show whatever's out there that we are much more advanced rhan we appear.This is the first maybe last "review"i may ever .I now have 2 new Xb10's sealed and if you understandibly skeptixql i will sell the community only 1 new one for $80 because unless you're very reckless and somehow need some crazy feature like a designated app for an iem/headphone amp-then with almost zero thought or care this is one for the ages.Only 1 little caution it's easy for it to go hide and be lost,.A 1oz baby black orb may seek a break sometime from you and may hope you biy another amp becauae its no fun being the only game in your little.musical world..If tou dont beieve this revoew shoot for the moon and spend $80 and probably not beloeve this lotlle black saucer wasnt created by some Nasa engineers who designed it and gave to the boys and girls who need rheir musix fix to look like and function like all the rest of their space cowboy toys..Thx!
