The Qudelix-5K thread

I have this one by Meenova from Amazon. Works great.
Unfortunately my experience using a meenova cable is not so great. after few weeks during which it worked flawlessly, the cable started to show issues due to a faulty contact…I now have to rely to bluetooth to use the 5K with my iphone. The pairing is rock solid and the sound enjoyable

Others here have had consistent success with this one.

Hi all,

I just got the new Samsung S22 Ultra. Going to developer options and selecting 990kbps, it still shows 660kbps in the Qudelix app. Any ideas on what could be the cause?

Check to see if you have any settings to select on the S22 as you make the bluetooth connection there. (Something like "best quality" , on the Qudelix 5K "tab" somewhere...) Can you get 990 when the phone and the Q5K are next to each other? When the bluetooth signal gets weaker, due to distance or obstacles, etc, the bit rate of LDAC will/may reduce to 660, and then as low as 330, before totally breaking connection. FYI, water absorbs bluetooth signals, so if phone is in back pocket, it's signal strength make be reduced, especially if the Q5K is clipped your shirt color, or shirt pocket. (As your body is 90% water and so, can block bluetooth signals,)

I selected the highest quality in developer mode on my phone (see the screenshot). and placed the phone and Qudelix 5K side-by-side. It really stays mostly at 330kbps in Qudelix app whereas in the phone option it's selected as 990kpbs (optimized for audio quality). I've done the same with other phones without any issues.

All you need to make sure is your S22 Ultra is using a 5G WIFI connection and not a 2.4Ghz. When I switched from 2.4Ghz to 5Ghz Wifi, I can get steady 990kbps on my S21 and A52 G5 galaxy phones using LDAC.

I turned off wifi, and got 660kbps.... this is really weird.... I can't manually change the to 5G from 2.4G as my router (Netgear R7800) intelligently manages both under a single SSID. As soon as I turned on wifi, it immediately switched back to 330kbps! Thanks for the help!

For what it's worth, my phone does not remember the settings, either. I have a POCO F2 Pro and my Wi-Fi is 5G from Virgin Media. I am on Android 11. In the past, like a year ago, I remember going into Developer once, forcing LDAC 909/990kbps there, and it was remembering it, even after shutting down my 5K. Now, not only it defaults back to Best effect (adaptive bit rate) after shutting down the 5K, but even during playback, if I will get away from the phone, it switches to adaptive before starting dropping the connection.

All this LDAC bitrate nonsense has me just using my Qudelix wired instead of Bluetooth. I actually switched from the POS Pixel 6Pro to an iPhone 13Pro. I use a lightning to USBC cable with the Qudelix, and now the only thing I use Bluetooth is just the AirPods Pro. I had really high hopes and expectations for the Pixel 6Pro, but that did not work out, especially when it came to LDAC.

How big is the difference between LDAC and APT-X adaptive; from a human perspective?
It is as big as it was tuned to be. Several people involved in the development of BT gear told me that each codec’s output is, or should be, tuned by an audio professional.
This is, I suspect, the main reason why people perceive LDAC as more detailed or higher-fidelity, it’s the audiophile codec by default and the devs tune it as such but you can actually do a good impersonation of it with vanilla aptX.

do you have to adjust anything on the 5K or just use the cable and plug it in?
