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

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.

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.

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).

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.

This unit works great with my echo dot and my yamaha RX v673 receiver. My 2nd zone speakers are built into my kitchen and dining room. This bluetooth receiver is plugged into the aux1 connectors on the back of my receiver...which by the way is in the basement, one floor down from my echo dot, AND horizontally 25 feet away.I have to say, I'm impressed. I was skeptical the echo dot and this bluetooth receiver would stay connected at this distance with the stone fireplace obstructing it. I should note that we otherwise have a very open floor plan so the signal may be working around the fireplace...still it's on a separate floor.The bluetooth audio sounds great, the pairing with the echo went smoothly and it actually stays connected to the echo dot. I've yet to hear a "reconnect tone" like what has been reported in reviews of other competing products.If you've got an echo dot and you want to use your receiver with it this one works well with it. With the audio coming out of the ceiling now, it feels like Alexa is sort of "built in" to my house now.

This little thing enabled me to connect my Bose radio with my Pandora and I love it! Beautiful sound with my Bose, and no commercials.

I have no affiliation with this manufacturer but now I ONLY BUY ESINKIN WIRELES BLUETOOTH RECEIVERS! I have 3 of them in my home at this point and I was initially trying out products from different manufacturers but I kept running into the same issue with the others. The other devices were significantly limiting the volume of the device that they were attached to. I would have the volume turned up and the device was not loud at all. I have not encountered this problem with an Esinkin Bluetooth audio adapter. Save yourself the hassle of making a return and just buy Esinkin first. They have different models to choose from if you are concerned about competing connectivity issues among the devices in your home. Thanks, Esinkin!
