esinkin Bluetooth Audio Adapter for Music Streaming Sound System, Wireless Audio Adapter Works with Smartphones and Tablets, Wireless Adapter for Speakers

Extremely Useful
Well worth buying if you are looking to make non-wireless audio equipment wireless, using Bluetooth technology. As long as the equipment you want to make wireless has either a 3.5mm audio port, or RCA type Left & Right audio ports you are all set. In my case I wanted to improve connectivity to an excellent (but out-of-date) Bose CD/Radio player. I used the included RCA connections for the radio, and this wireless adapter’s corresponding female connections. Then I finished it by using the included power adapter required to power this Bluetooth adapter. When placing my Samsung S5 phone into Bluetooth mode, and after pairing the two devices, it connected immediately to this adapter, transferring all sound to the Bose radio. Both the phone and Bose radio had control over the volume range, although the stereo will have the greatest control, as expected. The resulting audio sound output is excellent – better than I would ever get from the Samsung phone. Obviously, the broadcast quality from a radio station is simply passing through to the audio equipment (and the resulting sound quality is now solely dependent on the quality of the audio equipment you are using). Note: If the sound origin is from your phone, double check the Bluetooth settings for this device, AFTER you have connected to the adapter (select the settings icon adjacent to the name of this adapter to make sure, at a minimum, that Audio is active, and Calls [if available] is deactivated). While you are at it, you have the opportunity to rename the device – especially if you plan to install more of them. With this unit, don’t bother to look for an On/Off feature on the unit itself. There isn’t one. It’s just a small circuit board and it won’t put you in the poor-house if it runs 24/7. However – should you be obsessed with only having it on when you use it, just unplug it from the unit itself, instead of unplugging it from an outlet. But a word of caution – No Circuit board likes power surges, brown-outs, or lightening strikes. If you temporarily have electrical supply issues due to an approaching storm, I would immediately unplug it from the wall outlet ASAP, thereby protecting the adapter and the power supply unit. Several folks have, in their review, mentioned that when turning on Bluetooth with their device, it would immediately connect to the adapter (after it’s been paired for the first time, of course) rather than let you pick what Bluetooth device you wanted to connect with, as most other Bluetooth devices do. This is true. However, I don’t find that to be troublesome at all. First it shows great Reliability and Repeatability (two good Quality Assurance characteristics), and secondly, you can always select another Bluetooth choice displayed, and it will connect to it, and disconnect this adapter. Speaking of Reliability, I have run this Bluetooth adapter for hours at a time, and it has never dropped out, sought re-connection, or displayed any other anomaly.Now, a couple of extra notes about this adapter: Pairing the unit to your originating source is simple. Press and hold the square button in the middle of the unit until the unit has a blinking blue light. Go to your phone/computer/other device that has Bluetooth on, and select this adapter. After it is paired, it will always connect in future use. The power adapter cord measures about 71 inches long. Very generous to reach a wall outlet without using extension cords. However , a multiple outlet extender with surge protection would not be a bad idea. The RCA cord from the adapter to your attached system measures about 61 inches – plenty to do the job. The included pictorial instructions show a variety of connection choices and is very good. The box that everything comes in is very strong & sturdy (a keeper), but I found the slide-on outer “description-advertising” cover to be very tight to the box and wouldn’t come off without tearing it, which I didn’t want to do. So, I used a thin knife and slid it along the glue line of the overlapping paper (where the bar-code is printed), and it came right off. Afterwords, I used one run of adhesive tape to rejoin them with just a little more separation so that the slide-on cover would be easier for on/off use.The unit does provide a 3.5mm cable connector, but I did not try it. I used the RCA cable instead, which works as I expected it to. Before I discovered and bought this adapter, I had connected a 3.5mm connector directly from my phone to the same type connection on the Bose radio, and although it played, the volume was next to nothing, even with everything turned up, both on the phone and the Bose radio. Not acceptable. On top of that, it would force the phone to be hardwire tethered to the Bose radio. Again, not acceptable. The only solution was to buy and use this great adapter as described earlier. This also gives me freedom to go into any other room and still be connected, and listen to audio (locally from the phone, or via a streaming internet connection ) broadcast through the Bose radio!I love it when a plan comes together! I plan to buy two more of these, one to connect to my TV, and one for a spare backup. Enjoy one of these! You won’t be disappointed!

Simple, basic, just right for pre-amp audio signal
This unit has a lot going for it. It works exactly as it should, it’s not fussy and does not require an app to set it up, etc. Set up was simple and uncomplicated. Phone connects to it automatically and begins playing as soon as connected. No need to fuss around with phone settings each time. Note: initial volume on phone connection was turned all the way down, so if no sound, check that first. My phone remembers the volume setting for each device so it’s a set-it-and-forget-it connection.It comes with two different options for power supply, a 120v plug and a separate USB-A plug. It also comes with an audio cable that has RCA on one end, and 1/8″ stereo jack on the other, so it works with just about whatever you’re connecting to. It has RCA-out as well as 1/8″ stereo-out, so just turn the cable around for whatever your application is.We have a 30-year old Kenwood amplifier in our home gym that obviously does not have any wireless abilities despite being a really good driver for the gym speakers. Our last bluetooth adapter that we used on this had an internal battery that died after a couple years and rendered it useless. This does not have an internal battery (so it’s not portable) and should likely have a longer life. This amplifier has accessory outlets on the back for other components that come alive when the amp is turned on so all we have to do is turn the amp on, and bee-doop, audio connects and starts playing. Two small strips of double sided tape keep it in place.It would be handy if it came with some double-sided tape. It has a “non-skid” rubber bottom, but it’s so light that just the weight of the cables makes it do a wheelie if not held down somehow.

This Bluetooth audio adapter is a fantastic product that makes it easy to add Bluetooth connectivity to any non-Bluetooth device. The connection process is straightforward, and the sound quality is excellent. It’s a great way to enjoy wireless audio streaming from your smartphone or other Bluetooth-enabled devices. Highly recommended!

This Bluetooth adapter works great! No fuss and quickly connections to my phone every time. I was pleasantly surprised since it was so inexpensive.

Excellent product .

Branché sur un ampli Yamaha d’ancienne génération mais fonctionnant parfaitement, le voila remis au gout du jour. ce petit appareil est facile a connecter et a appairer. la qualité audio est bonne pour du streaming et sur mon ampli il y a deux sortie 240v dont une libre il est branché dessus comme cela il s’allume et c’éteint en même temps que l’ampli.Nickel surtout pour le prix
