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

This little thing is absolutely amazing!! It works soooo well. I have an older (late 90s) NAD receiver that is incredibly clean power, but obviously no wireless capabilities. I mainly listen to records or CDs, but my 18 year old son loves to show me new music he likes and sometimes we sit for hours in the living room just going back and forth playing songs for each other from our phones.I saw this and figured, for $22 why not give it a try? It really is amazing, simply plugged in the included RCAs to a TAPE 1 aux (since i don't use a cassette deck) and plugged in power. Hit power button, turned on phone Bluetooth, and boom...started playing music.The range is great, I didn't scientifically test it out or anything but even walking 20 or 30 feet away it was functioning perfectly. IF you plan on doing 80+% streaming, a Wiim Mini or Pro would definitely be better and worth the investment. However, if you aren't strictly streaming and want to add streaming capability to an older receiver....this is DEFINITELY the way to go in both performance, ease of setup/use, and value. I can't recommend it enough!!

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 In my case I wanted to improve connectivity to an excellent (but out-of-date) Bose CD/Radio player.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!

Only four because perfect should be impossible. Most hassle free Bluetooth experience I’ve ever had. Got one in spring of 2023 to use some super high quality PC speakers for home stereo since we don’t have a PC any more. Worked so well I got another one when I found a pair high quality Bose self powered speakers for super cheap. Now I don’t have to miss out on super high sound quality from _slightly_ older stereo speakers. And this Esinkin Bluetooth adapter connects more hassle free than any other Bluetooth product I own whether it’s car or portable speakers.
