Review: Punches Above it Weight - The Wii B03Pro is a fantastic choice if you're looking for a 5.0 Blutooth receiver to stream music. In this review I'll only be speaking to the audio part in relation to a stereo receiver through the use of iTunes only. I have a recapped 1980 Pioneer SX-3800 stereo receiver connected to a set of KEF iQ1 bookshelf speakers. My Pioneer receiver does not have Blutooth which is expected regarding integrated stereo receivers from the '60's though the very early 2000's. The first thing you should know is that like all Wii products, it's lightweight (plastic) and yet, it does not feel cheap. The B06Pro has a built-in ESS Sabre DAC so you're going to get improved sound quality than cheaper blutooth receivers. The top display is easy to read and not overly present with brightness from the LED's. The display provides very basic info regarding the particular connection and nothing more. It will NOT provide song information. You'll have to spend a little more money to buy the B03Pro+ to get a active sophisticated screen display. This unit comes with a 3.5mm to RCA cable, USB Cable, a Toslink cable, and a 5 volt power supply. The setup is straight forward and you'll be up and running in a matter of minutes. You also have the option of using an external DAC if you prefer. Regarding the 3.5mm to RCA cable connection, there is a misconception, in some circles, that such a connection has inferior sound. That's not true at all. That opinion is nothing more than a misinformed audiophile bias toward traditional RCA to RCA connections. If you don't like the included 3.5mm to RCA and/or Toslink cable then you can buy a higher quality cable on desertcart to easily mitigate the issue and you'll be on your way. I have an iPad from 2021 and an iPhone 12 of which to stream from as well as my MacBook Pro all of which connect very well with iTunes. If you have an Android phone or Microsoft tablet/ laptop / or desk top PC with blutooth, you'll also be good to go as the B06Pro has all of the usual codec compatibilities. It's small and I do like that it has an on/off power button and an on-board volume control which is surprisingly not options for the iFi Zen Blue 5.0 receiver that costs roughly $120 more. The big thing to consider is the price point of $79.99 It's considerably cheaper than the above-mentioned iFi Zen Blue, Audioengine, Lavaudio, and Blu Dento 5.0 or 5.1 bluetooth receivers. The audio quality from iTunes has been excellent when used with this device. Instruments are separated and quite detailed. I have not heard any noise or experienced any interference with the signal during playback. Overall everything sounds clean, articulate and full. Keep in mind that your listening experiences may vary. We all listen differently and own different audio equipment in different sized rooms, so reviews regarding sound quality are always quite subjective. I highly recommend getting the added product protection. For roughly $8.00 at the time of this review you get 2 or 3 years of protection in case something goes wrong. Everything is an investment so by all means, get the protection plan for peace of mind. If you're on a tighter budget, in need of adding blutooth to your stereo setup, and still want to get some higher quality sound, then the Wii B06Pro should be on your short list of considerations. Thanks for reading!
Review: Best Bluetooth Transmitter! - This would be my fourth Bluetooth transmitter I've tried for connecting my wireless Bluetooth headsets for watching TV, and it's by far the best one. All the others had various pairing issues, limited features, lag, poor signal range, etc. This one solved all my needs. Pairing and connection--it's fast! My headsets almost instantly reconnect on power up. Other devices usually take a few seconds. Pairing is super-easy, and it identifies the correct mode to use--whether it's atpX, atpX LL, AtpX HD, etc., so you don't need to fuss with any of that. Range - fantastic! Other devices I've used usually start to break up if I walked downstairs in my house (transmitter upstairs). With this, I can not only walk downstairs, I can be on the other side of the house and even in the attached garage without any of the signal breaking up or BT disconnecting. AC powered - don't bother with those other devices that need to be recharged, if you don't need it mobile. Features - every aptX/non-aptx mode you'll need, and it can support one mode for the first headset paired, and another mode for the second, simultaneously. All auto-negotiated. One con, but not unique problem to this device - it auto-pairs to any BT audio device that's in pairing mode and in range, if you don't have two BT devices connected at the time. This can get annoying. Imagine you're watching TV, and your spouse has a BT speaker in another room that goes into auto-pair mode when it turns on--it'll suddenly blast the TV audio! The only workaround is to making sure you have two devices connected when another auto-pairing device is powered on--after that stops pairing, you can disconnect the second device. What a pain.

## Questions & Answers

**Q: Can you change which of your 2 bluetooth devices you're are streaming too?**
A: Not automatically no. It’s quite mechanical. You either connect or disconnect a device. If u want to choose which headphones to connect to, you either have to do it from
The transmitter (which is not so straight forward), or you will to unpair / turn off the headphones that you dont want to use.

**Q: Will this connect to the bose s1, extending the distance? some dj gigs i need a wireless speaker set up.**
A: Two of them as a pair (one in transmit mode and the other in receive mode) have a theoretical line-of-sight transmission distance of 265 ft. So if that is greater than your present Bluetooth limits, and your Bose speakers have standard line-level input jacks, the answer to your question should probably be “yes”.

I’m presently using two across opposite ends of a home theater, and the nearly instantaneous “lip-sync” transmission of extremely high-quality stereo audio is truly impressive.

**Q: will this connect to a radio with a 3.5 mm headphone jack? . The radio in not bluetooth but I want it to transmit BT**
A: You can use AUX3.5mm to connect the radio and B03Pro+, and then use a Bluetooth headset to pair with B03Pro+ via Bluetooth.

**Q: Can this pair with Jabra Elite 75t**
A: Don't know, BUT It will not pair with 4  different bluetooth speakers I own. It will pair with windows laptop and desk top HP.  speakers I bought from Amazon (Doss Soundbox XL)  Will not pair. 1 out of 5  rate score for me. Amazon sent me a Email or I wouldn't waste my time. But fill my in box and you shall receive.  Buy the cheep one, check the Frequency of your device FIRST !!!

### ⭐⭐⭐⭐ Guess it is okay for the price
*by G***R on December 12, 2025*

In a pinch for digital connections, it will do nicely. It looks nice, with a small foot print and elegant gold-colored plating on the switches. For sound quality, it's about what you would expect for any digital setup -- certainly not on par with high-end-analog, but quite serviceable. I haven't listened closely for noise yet. On range, using this unit as a receiver, the connection reaches 30 feet into another room -- line of site, no walls, some furniture. My "phone" is able to play MP3s through my high-end sound system. The downside is the laughably, comically short cable and plug lengths. While this is industry standard for cheap good like this, I cannot let them off the hook. The cable barely reaches from one end of my amplifier to the other, much less out the back and to the unit home next to the turntable. An extension solved this problem, but why should an extension be required? 6' cables would be better.
