I bought since 4 Days from Amazon.de.
I make directly nen Firmware Upgrade to Version 01.22 over the iOS SoundCore-App.
My Wife ( 38 years ) and Me ( 40 years ) can’t here any hiss / white noise. When I hear music low / mid / max volume ( no hiss in silence parts of the music ).
pause the track ( low / mid / max volume ), also no hiss.
With the check in the SoundCore-App ( HearID ) I can hear all checked frequencies in all volumes with both ears.
perhaps the fix is only works with iOS devices or so.
The max volume is very loud ( loud enough ) and much more then the Limitation from the EU.
A little bit more infos to the Setup:
iPhone 11 256GB iOS13.3
Anker Soundcore Liberty 2 Pro FW 01.22
iPhone uses the AAC Codec, because it’s an iPhone.
can it be, that the problem is at a moment only with the aptX Codec and will be fixed in a few days…
A little bit to my person:
I’m 40 years old and hear often music over my HiFi Setup since years. I’m an IT Spezialist.
HiFi / Surround Sound / Home-Cinema / Video-Filming is an big hobby since 25 years.
