Fiio Control app hangs forever trying to connect to BTR7 - the read loading circle never goes away after i click on the BTR7 to add the device. Samsung Z Flip 3. I tried restarting both devices, no luck. Any pointers @FiiO?

Update: I didn't realise it was connected to both my IOS and Android device (IOS was control) so a new control couldn't be added on Android. Schoolboy error
Dear friend,

Yes, the FiiO Control app may not work fine when BTR7 connecting to two device at the same time. So you need to disconnect it from one of the device first.

Best regards

@FiiO @FiiO Willson Track ff and rew works in Bluetooth mode using volume controls on BTR7 but not in dongle mode on Android, can you please confirm if this is the case?
Dear friend,

Yes, the remote control in BTR7 is not available in USB DAC mode.

Best regards

What is retail price in Europe for the BTR7 ? Zococity is selling the M17 1999€ for a retailing price in Europe of 1799€…
Dear friend,

You could try to confirm this with the seller. Thank you!

Best regards

I noticed the BTR7 was warm still in the morning after full night wireless charging - it should have some battery care mechanism: charge full, then turn off charging and wait until less than 80% before charging again.. otherwise it's constantly topping off 1-2% and is constantly hot, can damage battery

Dear friend,

When the BTR7 is fully charged by the wireless charger, if it is still placed on the wireless charger seat, the BTR7 will be warm still, which is a normal phenomenon. And other products which support wireless charging will also have the same phenomenon. Currently, the BTR7 will not show a fully charged icon when charged via wireless charger. This issue will be fixed in the later update.

As for the battery protection function, we will report to the engineer for assessing. Thanks for your kind feedback.

Best regards

How do you get LDAC with 44khz? My BTR7 always displays 96khz, even if i change LDAC on my device to 44khz
One way is to force 44khz in developer settings for android devices.

Yes I did that - when the initial connection is made it defaults to 96khz ldac, I then go to developer settings and change it to 44khz but BTR7 keeps saying 96khz. I can see that on my device 44khz sticks (it also works with Qudelix which shows 44khz).. it's as if the btr gets stuck on 96khz

I tested the BTR7 with iUSB Micro 3.0 feeding it USB signal - significant improvements; obviously the Fiio has room to grow with quality sources. Something like the Qudelix has it's limits with scaling up, but the BTR7 sounds like a little desktop setup when fed good signal (reclocked etc) - it scales up more than the Cayin RU6/Qudelix ever did.

Essentially with the iUSB it gains:

* More warmth and bloom
* More smoothness, less grain
* Bigger soundstage, more depth.
* More dynamics and bazz
* Everything is better defined, previously unheard details emerge but in a relaxed manner.
* Still retains it's sabre/thx perkiness, it's not warmpoo but just calmer/smoother.
* Still keeps that slight thx restraint, like it wants to keep full control of everything - it's a general thx thing. I would love to see Fiio in the future tackle discrete class A amplification.

I would love to have this sound over LDAC - but such thing doesn't exist in this universe.

Anyway - good stuff. I've mostly been testing it with IEMs. I will try some overhead Sennheisers soon.

If BTR7 does not explicitly support 44.1khz LDAC, I did not see it advertised in spec as in case of Qudelix, the bandwidth will be negotiated based on what both transmitter and receiver can support, 96khz.
Just a guess, FiiO can confirm.

I saw on the pictures shared here, BTR7 displaying LDAC 44khz on it's lcd.

Any reason why you want 44.1kHz instead of 96kHz?
