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

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! 👍👍

Simple to setup. Easy connection. No issues.

I was hoping to control our older but excellent Bose system speakers with subwoofer without manually plugging my smart phone via AUX jack. This did the job. Simply plug it in, connect via bluetooth. Couldn't be easier! I'm so happy to be able to lay in bed and control the music wirelessly from my phone. AC adapter is about 5 feet long which was plenty for our needs. A couple of small issues: * You have to leave the speakers powered on - so even when music is turned off, there's a barely audible buzz in the air. This is probably a limitation of our speakers, not the controller but something to consider! * Bright status light - we had this on our dresser and you wouldn't believe how much ambient light the status light put out. I don't know why all such devices don't use red or orange lights as they can disrupt sleep patterns and I find them generally annoying. I put dark tape over it, problem solved. * Soft rubber top with large NFC top looks nice when you get it but collects dust and looks grimy. None of these issues have anything to do with the function, which was pretty great and reliable (for a bluetooth device). I'm totally happy I got it.

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.

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…

Easy install into aux port of amplifier/mixer. We power off sound system after each meeting and needed a BlueTooth receiver with good range that would power up in ready to connect state. This Esinkin model A201 works great throughout our meeting hall.

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!
