Seems like most phones actually default to 660kbps, with only LG V30 going to full 990.
On my phone, the Xiaomi POCO F2 Pro, leaving LDAC to best effect (adaptive bit rate) can get the bit rate up to 990 kbps. I've checked this using my Qudelix-5K, I am listening to it right now. On the Qudelix, I've set it like this: sample rate 96kHz, bits per sample 24 bit. As long as the phone is next to me, the bit rate stays constant at 990 kbps. Sometimes it fluctuates for a second but then returns back to 990.

The amazing thing with my Qudelix is that I can leave the phone downstairs and be upstairs listening to music or move all around inside my property. With LDAC best effect, I am not getting any disconnections and the bit rate fluctuation is completely inaudible, nothing changes to the sound I am listening. With the BTR7, I need to have my phone with me or be in the same room with it. Why is this happening when the BTR7 has the same Bluetooth chip (Qualcomm QCC5124 Bluetooth System-on-Chip) as the Qudelix-5K?

One question, guys. Let's say that I forget the BTR7 charging overnight. Does it have any safety mechanism to stop charging after it will reach 100% battery level?

Anyone?
@FiiO ?

This is entirely my assumption.

Although the BTR7 does not get particularly hot during charging, it seems to me that when it gets to 100% the device gets cold, when plugged in.

My guess is that at that point it is no longer drawing current so the likelihood is that it is designed to stop charging when it gets to 100% charge.

When I charge the BTR7 with a 2500mha external battery pack -> it stops charging when BTR7 is full (battery pack turns off) or even if the BTR7 is on connected by BlueTooth but not playing any music ! ..
It's becoming cold .. It's hot when it's playing music that's all.

Thank you, guys! I appreciate it! So, it automatically stops charging when the battery is full. I am charging it via USB.

Question - when you listen to MQA, does the unit display the correct unfolded bit rate? Mine (from Android phone) shows MQA, but always 48K, not the actual unfolded bit rate. I am on the latest FW.
Sorry for late respond, but I didn't see the notification.

I dont usually play via usb, but recently try with cable + uapp/tidal and found the same issue. Always appear OFS when tries MQA

Hey guys,
My BTR7 makes a noise and reboots it's self when used in conjunction with BTA30 Pro. I assumed this was a defect and swapped it out today with a new one.
Unfortunately, same issue on the replacement. :anguished: Has anyone experienced this and know of a fix?

I neither have the BTA30 nor the Pro version (yet.....temptation in check for the moment) but my question is, does the reboot occur after a particular event or during some process, such as changing codecs?

Hi, even though I own the BTA30 Pro for a few months now, I very rarely use it because I am waiting to buy a desktop computer and permanently connect it. Today, I've connected it to one of my laptops and for the few hours I am now listening (LDAC), I have not observed anything unusual. I know it is very little time to test, though.

What I have observed is that skipping to next/previous track on the BTR7 does not work. Volume up/down and pausing the track, work. Next/previous track does not work.
I am listening to Amazon Music Unlimited using the App on my laptop. I am also using SounDevil (player) using local .WAV files. Next/previous works fine when connected to my phone, of course.

@FiiO , why is Next/Previous track not working, when BTR7 is connected to the BTA 30 Pro?

In any case, the sound is amazing and, more importantly for me, the combination BTA 30 Pro + BTR7 appears to have a bit more Bluetooth connectivity strength, compared to my BTR7 + my phone. This is important for me as I am using all these devices to listen to music in the best possible quality, while moving around the house doing various things.

PS: to be honest, my BTR7 stopped playing one time, in the few days I have it. I am always using it with my phone on me or in the same room. It just stopped playing. I rebooted and it worked again. This happened one time.

It just happens randomly but each and every time I use it.
I have been using LDAC exclusively because it sounds the best to my ears. Tried factory reseting both devices, turning off "Boost mode". Nothing seems to work.

@Chibs , does Next/Previous song work for you on your BTR7, when paired to your BTA30 Pro? Mine does not work.
