Bluetooth Audio Transmitter and Splitter is rated 4.0 out of 5 by 11.
Rated 5 out of 5 by from Works well, does split signal to two devicesBought this to connect two Bluetooth devices from one source for backyard parties. Works well, seems to have decent range, I got 40 plus feet line of sight, though your mileage may vary. I keep the source/ transmitter within 30 feet of each speaker to ensure a good connection.Requires a certain technique to get the transmitter to connect to both devices:First, you need to pair each device separately. Follow the instructions for paring.Turn on the first speaker (or whatever it might be) and pair.Turn off the first speaker and then turn on the second speaker and pair.Turn everything off, then turn on the two speakers (or whatever it might be) that you wish to pair with. Make sure the transmitter is off before you turn on the speakers.Turn on the transmitter and keep pushing the button until it flashes the Red and Blue LED's which indicates pairing mode. If you only hold the button down till the Blue LED flashes, it will only connect to one of the two speakers. If this happens, turn off the transmitter and then turn the transmitter back on holding continually until the Red and Blue LED's start flashing.Give it a few of seconds and both speakers will connect. It sometimes takes the second speaker a little longer to finally connect but it does. Again, if it blips, turn the transmitter back off and then back on holding the button down on the transmitter until you see the Red (and Blue) LED's flashing. Does not seem to be any lag of music between the two speakers.I tried it with several Bluetooth devices and as long as the two devices I wanted to connect too were turned on, they paired with the transmitter. Instructions state will keep 8 paired devices in memory UNLESS you hit the transmitter button twice while it is on, then it erases all paired devices and you have to start over.Enjoy!

Rated 4 out of 5 by from Good deviceAfter using the Bluetooth transmitter for a while, I have come to like it. It found my Bluetooth speaker upstairs in my living room quickly. The only aspect of this device that I think could be improved upon is the head room. I have to watch how much input signal I am putting into it or when the Bluetooth speaker sync's up, I get blown away until I can turn down the volume.

Rated 5 out of 5 by from Blue Tooth XmitterI purchased the Blue tooth xmitter to use with my Blinc M1 Motorcycle/Scooter communicator. The device was paired in seconds. Audio quality was really good. I may by another to use with the audio from my GPS device. A big thumbs up!

Rated 2 out of 5 by from Not a splitterThere are very poor instructions as to how to use it. There are no instructions at all as to how to use it as a splitter. If you turn it off, you have to pair it from Start

Rated 3 out of 5 by from Has Slight DelayThis product does work as stated, but took a minute to pair with my headphones. On a side note: I bought this to work with my Yamaha DGX-505 but upon using, would not recommend it for such, as it has a slight delay from when you press the keys to when it hits your ears. Great for prerecorded music and video though. Would not recommend for live performances.

Rated 4 out of 5 by from Works Awesome!!!Small light weight little gizmo that will tie any non-BlueTooth device to any BlueTooth reciever with speakers. Start your BlueTooth receiver device scanning then hold the button until it flashes red-blue and boom hooked up. I use it with my BlueTooth headphones to hook up to my TV. I use the RCA out from the TV with a RCA to 3.5mm male cable (couldn't find a Female), 3.5mm coupler (changes Male end to Female) and plug this Transmitter into the coupler. The RCA out from the TV does not have volume adjustment, since it designed to hook up to a A/V receiver for processing, but my BT headphones have volume adjustment so I am good to go. 4 stars because I am a little concerned with the wire/jack as it seems a little delicate so i will take care not to stress it.

Bluetooth Audio Transmitter and Splitter

Will this transmit am/ fm radio to bluetooth speakers ?

Asked by: Spencer l

I want to add BlueTooth streaming into my BMW X3 witch already has an AUX input from the factory. What is my best option, this, model #MB-CM15112B, or something else?

Asked by: DBookatay
This is actually a transmitter, so the MB-CM15112B would be the best option for this application. You will just need a short 3.5mm male to male cable to plug into the AUX port on the stock radio.

If this is a transmitter does it transmit the signal out through the cord to a imput on a preamp for a home stereo?

Asked by: Cl3atus
No, this device plugs into the source you want to send a wireless signal from, then transmits via Bluetooth wirelessly to a Bluetooth receiver.
