esinkin Bluetooth Audio Adapter for Music Streaming Sound System, Wireless Audio Adapter Works with Smartphones and Tablets, Bluetooth Receiver for Home Stereo

I've bought 2 of these, over a year apart, since I gave my first one to my wife to use on an old Bose wave system. This is a simple, small and flexible little adapter. Note that it only works in one direction - It's designed specifically to allow using a Bluetooth device, like a cell phone with an audio device that doesn't support Bluetooth. I use the eSinkin to let me listen to my music collection from my iPhone on my old Pioneer receiver - It comes with a 3.5mm to RCA connector adapter cable that works perfectly to connect to the RCA jacks for Aux in. You can reverse this cable and plug it into the RCA jacks on the adapter if your device has a 3.5mm jack for input, which is what I did with the one I gave my wife.Audio quality is outstanding - certainly as good as my old stereo and speakers can reproduce. Range is good as well - I can walk around the house with my phone and the audio still plays without interruption.Others have noted that it is pretty determined to grab my phone's Bluetooth connection regardless of my desires, but I fixed that by plugging it into the 'switched' outlet on my receiver so it only comes on when I turn on the receiver.I would whole-heartedly recommend the eSinkin Bluetooth adapter if you're looking to add Bluetooth to an older device. You won't be disappointed.

I have been dissapointed with some versions of Bluetooth audio receivers. I use this to play music from my Macbook to a classic hifi system. The unit is small, so great for desktops, and the method of pairing and turning on and off is very simple. An on, and pairing light is very helpful to have, Also, I much prefer using real RCA connectors rather than a mini plug with splitter, as I think the overall quality is better that way. This unit set up in minutes and restated the next day when I turned it on. The instructions, almost wordless, are excellent.

The media could not be loaded. If this review helps in any way Positive or Negative Please hit HELPFUL!!! It will help encourage me to continue my real reviews of products I've purchased.Pros: $Priced under $25 / Synced fast to my phone/ Nice soft tone on speakers while syncing to let you know BT is discoverable (Note if you don't want then just synch device before turning on your speaker system/ Small/ Blue light is a nice touch/ Comes with cable and power adapterCons: BT is not new standard (That said I think new standard was designed for more than just audio and since this is purely audio system does not appear to be much of a limitation), Cable provided works but if you want high end sound you need better connectors (will cost you maybe $10 to $20 on up depending on how high quality connectors you want to get for hoking to this system), I can understand the power adapter, but since it is 5 volts and low amperage I think a USB cord option would be nice. Lastly no battery powered option although it would not be hard to rig up to a power bank.Okay... I've had this a day now and as you can guess I love this device. The range for the Bluetooth is awesome in that I can bring my phone all over the house and not loose BT connection to my stereo. Only thing I don't like about writing a review like this is that it also makes a good reason to raise the price.. Okay I guess with that said if the price gets above $27 for this great device I would look at my other options if I were to get some for friends.UPDATE: 9/27/2018 Yes there was a lot of background noise at the beginning of my review as my neighbor is having an underground pool installed in his yard; it was not noise from this device.Thank you for reading my review:Again Please give this review a thumbs up. It is real. I've been on Amazon as a customer for over twenty years. I don't get compensated for my reviews. (Not that I wouldn't like to be.)

Only four because perfect should be impossible. Most hassle free Bluetooth experience I’ve ever had. Got one in spring of 2023 to use some super high quality PC speakers for home stereo since we don’t have a PC any more. Worked so well I got another one when I found a pair high quality Bose self powered speakers for super cheap. Now I don’t have to miss out on super high sound quality from _slightly_ older stereo speakers. And this Esinkin Bluetooth adapter connects more hassle free than any other Bluetooth product I own whether it’s car or portable speakers.

This is my first Amazon product review where there are not enough stars to give. I'd give this BT adapter 6 if I could. The Bluetooth connection for audio is maybe the best BT device I've every used. If you've used Bluetooth before, you know pairing can be a hassle. And when you disconnect and come back later, reconnecting sometimes takes extra effort. Occasionally with some BT devices, the best remedy for connecting is to "forget the device" and then pair and reconect. I'm mentioning all of this because of what I've experienced all too often with BT before -- and what I HAVE NOT experienced at all with this Esinkin BT audio adapter. The BT connection is almost instant. I never have any issues at all. In fact, two people here have connected at once. I have an older but excellent audio amplifier and this adapter easily connects to one of the audio inputs. Then I effortlessly connect my smart phone, tablet or computer via esiinkiin Bluetooth to play songs and podcasts through my studio speakers. I just hope it lasts forever. I highly, highly recommend this product.
