Review from AmazonBicast – XLR & USB-C Bluetooth 5.2 Audio Transmitter January 24, 2026
Works as Described. Easy Connections for USB C and XLR Direct Out.
I was able to set this up without reading the directions. That’s how easy the setup was.
Starting with the Bicast USB-C connection to my Dell G16 laptop (Win11 Pro), I paired with an Anker Sound Core 2, and then a FVYAO wearable BT speaker. Both are great products and support TWS (True Wireless Stereo) technology. Unfortunately, from the manual, the Bicast doesn’t support TWS even though two speakers can be paired. The same signal will be sent to both speakers, according to the manual. Not a deal breaker.
The RUFUS AI on the web page says it streams stereo to headphones. I got out a pair of older Altec Lansing BT headphones. My G16 connected to the BT headphones flawlessly. I was unable to pair my headphones to the Bicast even thought the LED’s indicated pairing. All other BT devices were turned off. Probably a Codex problem. Your BT headphones may work.
I didn’t have a sound board handy, so I used a Line 6 Catalyst 200 (2x12 200 watts) guitar amplifier that has a Direct Output. I paired it with the Anker, and it correctly sent the amp signal to the BT Anker. See pix.
While this might not be the way you would use this device as most computers have BT signals, the XLR/USB-C is designed to send a signal from Mixers to PA systems and 2 BT speakers and 2 BT headphones.
For me, I will occasionally use the BT speaker connection with my Catalyst amp so Mrs. Cool can listen to me make noise in the music room without having her eardrums assaulted.
One of the kids does sound mixing and gigging with signals sent to the PA systems. I’m sure he would like another tool in his toolbox.

Review from AmazonWell, I thought that connecting this into one of my speakers would make the speaker bluetooth. Funny right! You need to connect this to a speaker that has bluetooth. As a result, I can not test this because I do not have any bluetooth speakers.
That said, before I ordered it I saw a video review of this unit and I was really impressed by it's performance. It is easy to connect just by plugging it in. I saw that it functions really well. And it is a well built compact unit.
It did come in uncharged, so I had to charge it, but then found that I needed to connect to a bluetooth speaker.
I don't know it there are any similar units on the market or what they cost, but for the money, I think this is fairly priced. I just can't currently use it.
