esinkin Wireless Audio Receiver for Music Streaming Sound System Works with Smart Phones, Tablets and Car, Wireless Adapter for Speakers

Good little adapter/receiver. This product worked great. We were looking to have a way to play music from across the room to an older receiver and this device worked perfectly.It has great range on connection, easily 50-75 feet. Installation couldn't have been easier and there's nothing to operate it. Great buy for the price and utility.

Every year I help run sound for a holiday party. I bring a small PA for the jazz combo and in between sets I play songs off of my phone via Spotify. I've always connected my phone to the PA mixer via an RCA/lightning adaptor cable, but that left me tethered to the mixer if I wanted to change songs manually as opposed to just letting the playlist play continuously while I mingle. Finally this year, I realized, duh, I should probably get a bluetooth transmitter so I can move around the party. (Yes, I am slow to pick up on things.) I reached out Sweetwater and told them I wanted to spend $40 and they suggested an item for $110 and then an item for $60. I looked on Amazon and found this device for $23. I ordered it and it arrived on time, but the PA was already packed and ready to go. With fingers crossed, I arrived at the party, set everything up and with 2 minutes before doors opened, I opened up the box, hoping it would be easy, I even forgot my glasses so couldn't read any small print! I quickly plugged in the small AC adaptor to the device. I remembered reading that the logo was the bluetooth pairing button so I pressed it, it lit up and my phone paired within just a few seconds. I then took the RCA cable plugged it into the PA with the other end - the round 1/8" (3.5 mm) male end - going into an obvious and easy to spot female end on the esinkin device. Turned up the volume on the phone and the PA a little louder than before, and it was on!The entire set up time from opening up the box to hearing sound, all without looking at instructions, was about 90 seconds. The sound quality was totally great for this price point and I walked about 75 feet away to go to the bathroom without any loss or breaking up before I realized I better leave my phone inside the room.So, long story short, this device was a fantastic lifesaver! Gonna buy one for my car too!

This device functions as expected and was took nearly no effort to set up.I bought this because Apple play with Roku was be very spotty and would continuously drop the connection while playing music.This is also great because it feeds analog audio to my receiver and I am able to use the multi zone feature. I love being able to have sports on inside and music playing outside at the same time.

I had no issues getting this connected whatsoever. Plugged in the power, plugged an AUX cord from my receiver, my phone's Bluetooth recognized it immediately and it started pumping out music.My ears are not audiophile level, but the sound quality was acceptable for me, there is some quality loss, but I think only the most discerning ears would care. Honestly I noticed it most with phone notifications.Range-wise, we had mixed results. Sometimes, we take it outside the house by the pool and it works great, then you move it a foot and it starts to lose signal. The difference can literally be inches, one spot cuts out, turn move the phone an inch or turn it, and it connects fine. Within a certain range (I think they say 35', but no specifics were tested), you have no issues at all.We were thinking of buying a Bluetooth receiver, but for a fraction of the cost, and a lot less hassle, this Esinkin wireless audio adapter met our needs just fine.

The Esinkin Bluetooth device was incredibly easy to install. While it can be powered using a separate wall outlet, I opted to use the electrical plug on the back of my Yamaha receiver. This way, the Bluetooth device powers on and off along with the receiver, which is very convenient.Pairing with phones and iPads was simple and seamless. Switching between devices is also straightforward: the current device playing music needs to stop playback and close the app, allowing another device to take over by starting its music app.It’s hard to believe this tiny Bluetooth device has replaced my massive 300-CD player. Its footprint is just a fraction of the size, yet it offers unlimited music with streaming services. It’s a perfect upgrade for older audio systems.Overall, this device works great and adds reliable Bluetooth functionality to older receivers. Highly recommended for anyone looking to upgrade their audio setup effortlessly.

Great product. Does just what it should. Never misses linking itself when it is in the vicinity of a bluetooth device.
