Esinkin Bluetooth Receiver Wireless Audio Adapter 4.0（NFC-Enabled） for HD Music Stereo Sound System

Simple to setup. Easy connection. No issues.

Works Great! It receives bluetooth signal from my iPhone and plays the music on my old Bose stereo with great high and low range with good volume. Sounds wonderful! 👍👍

If you are one of those old farts like me who just could not bear parting with those bulky speakers and amp to landfill when they became obsolete 15+ years ago, it is your time to rejoice. Buy an inexpensive Bluetooth receiver like this and enjoy a true s-t-e-r-e-o. These days you can even bypass the phone and broadcast Spotify signal direct (works with Spotify Premium account only) which will give you even higher audio fidelity than signal from mobile phone. OK it is not portable like Bluetooth speakers but the audio quality is way better. You can talk to it and it does not talk back to you like Alexa. How refreshing is that? As far as the Esinkin product itself, it installs in minutes and works flawlessly. Go to your mobile phone, select Settings and Bluetooth and it will find this device in 15 seconds. Then you are good to go.

I was a little apprehensive buying this from a no-name Chinese trademark, but I'm satisfied with the purchase. The price is good, and the added convenience this gives my home audio setup is worth it. Pros: * Works great for freeing up my phone while listening to music or podcasts on my home stereo. * Audio quality streaming on my phone is good. There are a couple of reviews here talking about "high fidelity" and I don't know if I'd go that far, but I wasn't looking for an audiophile experience at 24 dollars, so I'm not counting that against it. * Doesn't fight for Bluetooth connectivity if you disconnect. * NFC is a nice add-on and it works well enough, though I don't know if it's that much more convenient than just connecting manually. Cons: * The reception doesn't seem super strong. The signal will occasionally fuzz out, sometimes even in close range. Annoying, but with how I'm using this, it's not frequent or severe enough to be a deal-breaker. * The LED indicator isn't overly bright, but when no devices are connected, it will flash non-stop (I ended up putting a piece of tape on mine).

Works as adveritised. I have this connected to my home amplifier using the included rca to 3.5 mm cable to listen to my computer audio library (in other room with a distance of 20 feet and 2 walls). No problem pairing, or connecting. Audio quality is excellent and as good as direct corded connection to amp. Once this unit powers on, it is ready to connect each time once initial pairing was performed with sending device. It will work and keep pairing with multiple devices but of course not simultaneously. I also use 1 or 2 phones to connect to amp. If you plug this into the switched outlets on the back of your amp, this unit will power up with amp and be ready to connect. I reserved writing a review until after few months use. All good on purchase. All good now.

This works very well with my Echo Dot. I am using it at a range of about 15 feet but I have taken the Dot out to the garage and the pairing still worked (range about 25 feet and two walls in the way). The output (and the output from the TV headphone jack) feed into a Behringer Xenyx 502 mixer and then a pair of Mackie MR-5 speakers. I cannot hear any difference between symphonic music from the Echo via Bluetooth and the same music via the Fire TV stick through the TV (I admit that have haven't blind-tested it). There is more detail about the setup in my review of the Echo Dot. Update: I've modified the setup and now have my Echo Dot hardwired into the mixer. I didn't try that sooner because I thought that the speakers would be too close to the Echo Dot for the voice commands to work but there is no problem. This seems to be the best sound. The stereo image is very well-defined. But I still give the Esinkin five stars - the sound is good and there are no flaws in performance like dropouts or inadequate range.

Loving it finally able to turn my old stereo into a new one Thanks Amazon…

I have this plugged into an amplifier to stream Bluetooth in a medium sized apartment. I have used four different devices, and they sync easily. I have to manually disconnect a device in order to connect to another one. The one that is in the memory will reconnect automatically when it is turned on and within range. This unit always needs to be plugged in. One thing that stands out to me is the pad underneath, which hasn't left marks and stuck to things after awhile like some electronics do. It beeps to let you know your device has connected. The blue LED light is small enough that you can put it behind something and it won't annoy anyone, even at night. The range is more than 20' (very reliable) and less than 30' (don't move) through 3 or more walls, and my particular unit seems to like it when I use my own RCA jacks instead of the 1/8" plug which was included. You can experiment with placement. Moving it over slightly could make a bigger difference than you might think in some applications. Sound quality is notable for a 20 dollar device, and consistent within its intended range. I was hoping that it wouldn't cut quality as you get farther away like some are designed to do, and that seems to be the case for me. For reference, you would be able to discern which of your recordings are better than others and which formats are "lossless" or compressed. It's not as detailed as my CD player, but might be comparable to a cheaper one. When I am streaming Bluetooth, chances are that nobody cares. I haven't noticed a noise floor coming through the unit, or any other sort of distortion. Designed in California, Made in China

Product meet my expectations. Would be good if it had a button to disconnect the current paired device. This would make it easier to connect a new device. Currently you have to open each device individually to find out which is paired. Can be a problem in a home where everyone has an iPad and iPhone

Easy to set up. Requires source (phone or iPad) to be close by or it jumps around a bit. If source is nearby it’s faultless.

Remarkably simple and easy to use.

Connected this unit via RCA to my old NAD 3020B amp with B&W DM220 speakers. Really quick and easy to setup and pair with my iPhone. Sound quality is surprisingly good. Only downside I've noticed so far is when I'm carrying the phone and walk out of range of the receiver, the phone disconnects from the receiver (as expected), however it doesn't reconnect automatically when I move back in range. But at this price, you can't have all the bells and whistles. Good value for money!

Easy set up and worked straight away without issue, where as previously more expensive Comisol adapter failed completely. Happy customer!
