How about just two types of cases, with and without clip, you can still keep ring for lanyard on both?
Because honestly this industrial strength thick velcro solution while ingenious is very unattractive and bulky.

I just received my BTR7 today, I bought it to give it a try. Can anyone please tell me the meaning of what is showing in the main screen? Right now it shows LDAC 96K/24B.
Why does it show that when I have set the Bluetooth audio sample rate to 44.1kHz, in the Developer settings of my Android phone? @FiiO ?

My very initial impressions: comparing it with my Qudelix-5K, they both sound very close/similar = amazing! The BTR7 feels more powerful. The only downside for me is that the BTR7 needs to be in the same room with my phone to function properly. With the Qudelix-5K, I can leave my phone downstairs and go in all the rooms, upstairs, without losing connection, ever! Both set to LDAC 990/909 kbps.

I saw this on the Fiio website, not sure if it helps answer your ? -

When connecting the BTR7 to a mobile phone via Bluetooth, and switching the bit depth in the developer options of the mobile phone to other bit depth options, why would the BTR7still show 24bit?

You will find that it will also display 24bit under SBC encoding. In fact, this 24bit refers to the audio processing bit depth after decoding through Bluetooth. It is not the same indicator as the bit depth in the developer option of the mobile phone, nor is it the same one as the track itself.

This is related to the internal DSP of the Bluetooth chip QCC5124. To exert the maximum performance and audio processing capability of the DSP, we have adopted the highest 24bit specification. All decoded Bluetooth audio will be processed in 24bit before sending to the ES9219 DAC.

Thank you for the correct reminder. Sorry we neglected to introduce how to use it. Please refer to the two pictures I added.BTR7 CLIP2.jpgBTR7 CLIP1.jpg
No, don't do it this way! The case will be damaged on the first day of use. And the velcro does not look good at all. It's abrasive, let alone it will damage the case after a couple of swapping attempts. There are lots of elegant designs, including this https://www.aliexpress.com/item/1005002537902984.html. Another design: https://www.amazon.com.au/Cellet-Replacement-Removable-Spring-Clip/dp/B0012NVPTO?th=1

Make a socket for the clip at the back of the case. Or simply make a plain BLACK LEATHER case without any clip and we'll attach a third-party clip to it. Whoever does need it. Because some people have to permanently attach a clip to the back of the device itself. Some people attach it to the gray case instead in order to save the wireless charging functionality but for me it's an ugly case that I personally would never use at all.

This design with the velcro is trying to be too many things for too many people and as such looks hideous. Velcro adds too much bulk, for those that want a lanyard Miter already make something for you in multiple colours (Black, Red, Blue). For those that want to retain wireless charging the existing included case as well as the after market case Miter case already does that. Please @FiiO just make a genuine leather case with a clip (like your first design) in multiple colours including black with the clip slightly higher up.

Thank you :)
The same answer is also posted in the beginning of this thread, I just didn't have time to read it.

So, what do you guys suggest as the optimal settings for Bluetooth on an Android phone? Leave everything at the default? Just forcing LDAC to 990/909 kbps, maybe? My phone defaults to Adaptive LDAC bitrate.

For best results use LDAC, go to developer options and force LDAC 990/909 kbps optimised for audio quality :relaxed:

Thank you, I will do that for when I will keep my phone in the same room. For now, I've set it to aptX Adaptive and I gained some more connectivity range. I can leave my phone to another room and still listen. But it cannot catch up with the Qudelix-5K, I can listen to that in any room or spot on my property, LDAC 990/909kbps. I appreciate the longer battery life and more power, though! Do you think that the BTR7 is capable to drive the HiFI Man Sundara or other planar magnetic headphones?

I don't own either of those headphones so I'm not qualified to answer that question, all I can suggest is to try powering them from the BTR7 and see how you go 🙂
