I received Fiio BT11 adapter.
The only positive thing is that the device itself looks great. However, there are continuous issues.
I connected the device to my Android phone (Huawei Mate 20) and the pairing indicator started flashing. I took the Mifo Hifidots TWS out of their case and after about a minute, they recognized each other and paired. The indicator turned green, indicating that the connection had been established via aptX Adaptive/lossless.
I tested the sound and it sounded good, but there were some crackles.
Then, I opened Fiio Control app and it didn't recognize the device at all. I checked the version and it was 3.29, which is the latest version.
Okay, so I decided to try connecting to a computer with Windows 10. Immediately, the headphones connected to the adapter but through the SBC codec (the lowest quality and most unsuitable codec!).
When I switched back to the phone, the connection reverted to the SBC codec.
And, since Fiio Control application does not recognize this adapter, there is no way to change this.
I connected Fiio BT11 to my tablet (Lenovo Legion Y700 2023) and the connection with my Mifo HiFi headphones was established via aptX Adaptive / lossless once more. The sound was normal and there was no crackling.
After turning on the Fiio Control app, the image from the Fiio BT11 appears. However, when I try to click on it, I receive a message saying "connection failed."
This also happens with my Xiaomi Redmi Buds 5 Pro TWS. These headphones work perfectly with Fiio BT11 and connected via LDAC (the indicator light is on in pale green). The sound is good, but there is no way to access the settings again.
When I connect the adapter to my computer (Windows 10), the connection still works through LDAC, which is one of the only positive aspects.
And the sound quality is also quite good.
To summarize: I can still use this adapter, but I can't configure it (at least choose the codec).
The connection process is quite complicated: you need to turn off Bluetooth on the phone, connect BT11 adapter, run Fiio Control application, and then turn Bluetooth back on. After that, BT11 device should appear in the app...
(I've tried other options, but they didn't work.)
Another downside is that with this adapter, you get two separate volume controls - for the headphones and for the system. It's not possible to make a single volume control, either. I didn't find that option.
And finally, the "icing on the cake": it's currently only possible to update the adapter firmware through an iPhone. For Android users, the manufacturer promises this will be available "in a few months."
In general, this is a very crude device. It is difficult to understand how a well-known manufacturer could have released it in this state for sale.
