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

Works as described. Must be plugged in as it has no onboard battery. Quick connection to iPhone with a pleasant confirmation tone that doesn’t wake up the neighbors. Great way to get more life out of a sound bar that has a non-functioning bluetooth. Now I can listen to my playlist on great speakers with no hassle.

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.

Recieved a week before promised. Came with all the nessasary cords, pluged it in, connected my phone and wallah worked! I haven't used it enough to check reliability. Hence 4 star review.

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.

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! 👍👍

I have a Bose Lifestyle 48 system in our master bedroom. I have an Apple Music subscription on my iPhone. This Bluetooth device is incredibly easy to set up and has worked flawlessly. You basically connect the auxiliary cable of the Esinkin device to the Bose unit and power on. Go to the Bluetooth settings on the iPhone and find the Esinkin adapter, then connect. Simple as that. I haven’t had a connection failure once and the sound is great. An easy, cost effective solution to access the thousands of songs in my iTunes library thru my Bose system. Could not have worked out better. Highly recommended.

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!
