    5.0 out of 5 stars Simple, easy to set up and works great!
    Reviewed in the United States on November 14, 2024
    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.

    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 adapter

    Cons: 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.) I pay for Amazon Prime so I get any of the perks that come with my Prime membership.

    5.0 out of 5 stars Simple, basic, just right for pre-amp audio signal
    Reviewed in the United States on August 30, 2024
    This unit has a lot going for it. It works exactly as it should, it's not fussy and does not require an app to set it up, etc. Set up was simple and uncomplicated. Phone connects to it automatically and begins playing as soon as connected. No need to fuss around with phone settings each time. Note: initial volume on phone connection was turned all the way down, so if no sound, check that first. My phone remembers the volume setting for each device so it's a set-it-and-forget-it connection.

    It comes with two different options for power supply, a 120v plug and a separate USB-A plug. It also comes with an audio cable that has RCA on one end, and 1/8" stereo jack on the other, so it works with just about whatever you're connecting to. It has RCA-out as well as 1/8" stereo-out, so just turn the cable around for whatever your application is.

    We have a 30-year old Kenwood amplifier in our home gym that obviously does not have any wireless abilities despite being a really good driver for the gym speakers. Our last bluetooth adapter that we used on this had an internal battery that died after a couple years and rendered it useless. This does not have an internal battery (so it's not portable) and should likely have a longer life. This amplifier has accessory outlets on the back for other components that come alive when the amp is turned on so all we have to do is turn the amp on, and bee-doop, audio connects and starts playing. Two small strips of double sided tape keep it in place.

    It would be handy if it came with some double-sided tape. It has a "non-skid" rubber bottom, but it's so light that just the weight of the cables makes it do a wheelie if not held down somehow.

    4.0 out of 5 stars Bluetooth Bully
    Reviewed in the United States on November 22, 2024
    This adapter works great, is very easy to use, sounds great and has a very persistent connection. That last point is both good and bad. If you only have one Bluetooth device in your home, or want an adapter that will prevent any other adapter from connecting to your paired device, then this is your unit. Otherwise, you may need to turn it off to allow any other adapters to connect. That's been my experience, and I find it annoying. AF.
