Astell&Kern Launches KANN Ultra DAP and AK HB1 Bluetooth Amp/DAC

Battery dropped 5% in 3 minutes via LDAC. Not great...

EDIT: the app is showing a battery level 7% higher after I connected via USB-C- seems like battery life estimates are a random number generator at present. I am disappointed that A&K did not consider it a necessity to include a case.

While the device is almost entirely made out of plastic, this doesn't mean that it doesn't need to be better protected.
A belt clip would have been appreciated, much like what the Qudelix-5K had.

This is a known issue and will be fixed in a future update.

After a number of requests, AK will produce a case for the HB1. It will be available as a separate purchase and be available in January. More info will be available next week.

Would also be good to add some sort of volume indicator. I nearly blew my eardrums out- the iOS app doesn't have a notification bar status window like the Android app and I did not suspect volume would be at nearly the maximum level.

There are plenty of lights available that can be used for the purpose..

EDIT: great to hear about the case, what is not great is that it will cost more on top of the RRP of £259.
Again, in my opinion a case should have been in the box, not a chargeable extra.

Will add this to the feedback list I am submitting to the team today.

The easiest thing to do would be to update the iOS app to be in line with the Android version.
The issue occurred as I moved from bluetooth playback to USB-C playback- the volume automatically went to 100% (I was playing through Roon Arc)

Hi, anyone did a battery test on Kann Ultra? my community praised this DAP so highly that even one who is not easy to please praised it. I have not had the chance to visit a local store for a listening test though.

According to manufacturer's specifications:
  • Capacity
    8,400mAh 3.8V Li-Polymer
  • Charge Time
    about 3.5hours (PD 3.0 Charger)
  • Playback Time
    about 11hours (Standard: FLAC, 16bit, 44.1kHz, Vol.50, LCD Off, Low Gain)
Yes, I confirm these battery life times.
With higher gain it is about 9 hours
If you use Kann Ultra in LineOut mode on a balanced output with BT enabled to control song switching, e.g. A&K PA10 - operating time 11 hours
When you use Kann Ultra only via BT on TWS headphones, the working time is about 11 hours
With the DAR function turned on, approximately 7 hours

There is 1.5 reviews online and no real comparisons against similarly priced DAPs, that must mean something. I was very interested in one against M17 as Fiio is less expensive and best DAP I have ever heard but no luck.

Our review was delayed because we received a preproduction demo and we were unable to run the firmware update, but once we received a replacement demo, I was able to give it a good evaluation. Regrettably I don't have a Fiio M17 on hand to test it, but hopefully it's helpful: https://bloomaudio.com/blogs/articles/ultimate-portable-audio-astell-kern-kann-ultra-review

@JasonNYC Talking about the HB1:
Please add a "Volume Lock" Function in the App. Especially in USB Mode and sometimes in my Pocket the Volume Wheel is suddenly moving and changes the Volume. Thank you!

Will it come with a Clip or will it be only a protective Case? Approximately how much will it cost?
