Customer Q&A

5 questions already asked

What is the difference between this unit and having an amplifier that has Bluetooth? I want to play the songs on my iPhone at their best quality. Should I be buying this and hooking it up to my Bluetooth 2-channel amp?
[ John  Dec 31, 2020 ]

The B-Fi unit receives your digital music over your wi-fi system that you have already in your house probably from your router. It is uncompressed and does not use bluetooth at all . When working it does sound slightly better than bluetooth 5.0 by my ears. My windows 10 will NOT play FLAC files but will play WMA lossless. My Galaxy 20S and Galaxy S9 will play both files with ease. The B-fi connects to the preamp section of your receiver via RCA cables. It also has to be plugged into a power source.
[ WAYNE  Jan 15, 2021 ]
Bluetooth is a one-to-one communication technology. The Streaming anchor-point (often an application on an iPhone which is connected to the music source, or iPhone equivalent) uses Bluetooth to connect to one speaker. As long as the anchor-point stays in Bluetooth range of the speaker, life is good. Connecting to a "powered (amplified) speaker", the Audioengine B-Fi device acts as an anchor-point and communicates through Wi-Fi from the music source. You use the free Audioengine iPhone app to connect and tie the music source to the B-Fi device. You are no longer limited to the Bluetooth range - you are now using WiFi. My reason for buying the B-Fi is that I wanted to connect more than one speaker together. With two B-Fi devices (up to eight are supported) you can group B-Fi's and their speakers together and they will will play the same music, synchronized. Hope this helps . . .

Can "YouTube Music" be streamed to the B-Fi using an Android phone!?
[ Michael  Dec 18, 2020 ]

No, You Tube music cannot be streamed using the Audioengine B-FI That's the reason why I'm returning the product. Hector
[ HECTOR  Dec 18, 2020 ]
The specs on the AudioEngine site say 16bit/44.1kHz, but here on Crutchfield it says 24bit/192kHz. What is the maximum resolution of this device?

Got this from an Audioengine engineer: Good afternoon from Audioengine, thanks for reaching out to us! When we were in the initial planning and development stages for the B-Fi, we investigated building it to be 24-Bit. What we found though, is that building it to work reliably as a multi-room solution wasn't feasible at 24-bit, and after fully exploring our options, we decided that multi-room functionality with great lossless CD quality playback was a more valuable solution overall. We know that some of the audiophiles out there may consider this egregious, but we're okay with that. To most, this is a reasonable trade-off.
[ Freddie  Dec 02, 2020 ]
We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.
