Esinkin Bluetooth Audio Adapter for Music Streaming Sound System

Today’s product is the Esinkin Bluetooth Audio Receiver. The package included the bluetooth device, an AC/DC adapter, USB power cord, RCA to AUX cord, and instructions manual. It’s pretty convenient having multiple options for setting up the device. I chose to use the AC/DC adapter since I will have it continuously powered by the outlet. I have a 2003 Pioneer CD player. This unit is pre bluetooth, however it does have an AUX input for an old school CD disk changer. Using a separately purchased, product specific 8-DIN to 3.5mm jack cord, I was able to plug right into the AUX line of the Esinkin receiver. One click pairs the unit with your mobile media player. I have several devices that I can now connect in an instant and play new content on my old school devices. The device comes with several useful attachments, although I need a separate adapter, I actually have had it for years, and have been using it for direct connect audio with this head unit. It is so simple and quick to set up, it almost made me skeptical, like it was too good to be true or something. The overall sound quality is great, capturing all of the details of the lossless audio files. I have my mobile phone and two tablets paired with this device, but my old Fire tablet is the one I use the most. I think that the Esinkin device is amazing at getting the job done. The item does exactly what it should, and I don’t see how it could be better. The price for this device, combined with an amazingly low cost, makes it a superior value that’s hard to beat. If you have some old school equipment that still works but you can’t play modern media players, then this device can solve your problem. I would highly recommend this as it is a great product for a great price. You can’t go wrong.

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 In my case I wanted to improve connectivity to an excellent (but out-of-date) Bose CD/Radio player.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

Both one for myself and it works well. Ended up giving it to my stepmom who wanted to play music from her cellphone to her stereo system. With the easy set-up and good rang / connection, I decided to buy another one for myself. Highly recommend

It works as it should. Seems to be reliable so far. I bought one years ago and it worked pretty good for a while. It’s a simple easy to use and easy to set up device. Can be a little glitchy if more than one phone or device is connected even after you select the one you are wanting it will connect to the other sometimes if you pause and come back in the room from being away from the device call me fussy with that but other than that which is not going to effect most people I would buy this as a budget friendly option to connect your device to a Bluetooth option to have a wireless connection even if your device does not have that option with this device you can make almost anything Bluetooth.!!

I like this! I acquired an awesome sounding, high quality Bose system that I use in my workshop. It's hard to beat the Bose sound quality but the system is old enough that it doesn't have Bluetooth. I have WiFi in the shop so I got this to use my phone for streaming music and audiobooks. The adapter works very well. There was a bit of a learning curve for proper integration and use but now it's very good. I've got Amazon Music, Chirp, Sirius XM, and others on demand in my shop! Now I just need to replace my sketchy WiFi extender to eliminate gaps. One small note: It was very evident when it arrived that it was a returned item. The box had been opened and not carefully re-closed and one of the factory protective plastic film pieces had been removed. I have purchased from Amazon Resale, formerly Amazon Warehouse, in the past and have had very good results so I decided to try it before doing a return. It all worked perfectly so I didn't return it.

If this review helps in any way Positive or Negative Please hit HELPFUL!!! It will help encourage me to continue my real reviews of products I've purchased. Pros: $Priced under $25 / Synced fast to my phone/ Nice soft tone on speakers while syncing to let you know BT is discoverable (Note if you don't want then just synch device before turning on your speaker system/ Small/ Blue light is a nice touch/ Comes with cable and power adapter Cons: BT is not new standard (That said I think new standard was designed for more than just audio and since this is purely audio system does not appear to be much of a limitation), Cable provided works but if you want high end sound you need better connectors (will cost you maybe $10 to $20 on up depending on how high quality connectors you want to get for hoking to this system), I can understand the power adapter, but since it is 5 volts and low amperage I think a USB cord option would be nice. Lastly no battery powered option although it would not be hard to rig up to a power bank. Okay... I've had this a day now and as you can guess I love this device. The range for the Bluetooth is awesome in that I can bring my phone all over the house and not loose BT connection to my stereo. Only thing I don't like about writing a review like this is that it also makes a good reason to raise the price.. Okay I guess with that said if the price gets above $27 for this great device I would look at my other options if I were to get some for friends. UPDATE: 9/27/2018 Yes there was a lot of background noise at the beginning of my review as my neighbor is having an underground pool installed in his yard; it was not noise from this device. Thank you for reading my review: Again Please give this review a thumbs up. It is real. I've been on Amazon as a customer for over twenty years. I don't get compensated for my reviews. (Not that I wouldn't like to be.) I pay for Amazon Prime so I get any of the perks that come with my Prime membership.

This worked perfect for my boathouse. I have an older receiver down there and I wanted to be able to bluetooth my phone to it. It was pretty much plug and play. Hook it up, turn it on, connect and it was working. The range was great too. I have the device inside a cabinet and I can walk over 100 ft away outside and it's still connected

Does it do the job: Yes Does it sound great: No Quick to connect, Setup was very easy. (Just need to power cycle it to get it in pairing mode). Works fine. Audio quality is decent (See negative below). Similar to connecting to a name brand bluetooth speaker such as a JBL boom box. Audio has a bad hiss/wine to it when not playing. Yes it does cut off after 2 seconds. But if you are playing soft music in a quiet environment. Such as an office, or reading nook as background music. You will be very disappointing with the quality and the hissing. This is slightly improved if you use the provided USB power adapter, vs the wall wart. That adds more hiss to the system. For the casual user who want to listen at medium or high volume. No problem, get it. But for those who are looking for quiet, background music. I would avoid.

Great for my home audio speakers that I couldn’t previously Bluetooth to. Super simple set-up, works every time.

No European power supply only US.....

funziona benissimo, piccolo ed elegante, unico difetto è l'essere sempre acceso; per chiuderlo devi staccarlo dalla corrente

Brilliant device, it connects my music library on my iphone to my lovely 15 yr old amplifier and speakers, great range and sound transmission is seamless with great sound quality, very cost effective and small unobtrusive, would recommend highly

Okay. This thing is legit.its easy to hook up. Instructions are literally no words just pictures. I have it into an amp with the rca to small aux. It works awesome. I did a test with a hard wire and coudnt tell the difference. Music clarity is great. It hooked up to my daughters and wifes phones 1st try with ease. ( both newer I-phones) .Mines a samsung s24, no issues. Its 14 feet up in a 16' X 24' insulated shop, inside a 40'x80' covered metal pole shed , and i can walk anywhere in the shop.and about 25 feet strait out the front.The cords do feel cheap and could use an up grade. Im going.to buy a decent double rca male ends like i said earlier and see if that boosts if even more,but best 30$ I've spent in a while.I was getting sick of leaving a ladder 🪜 there so i could change songs, etc. 5 stars pending future reviews But for Now. Its perfect.
