How to use

The use of such a device directly depends on its type. There are only two of them:

From USB. In this case, the power comes through this port and you need to additionally connect it to the cigarette lighter through another adapter or to another power source./wpsm_numbox] No USB. Here you just need to connect the device to the radio via a standard 3.5 mm input (for headphones)./wpsm_numbox]

Otherwise, the connection for both types looks the same. First you need to connect it to the radio (via AUX and or only via the 3.5 mm input).

Then on your phone or other device on which music is stored, and find an adapter there.

When the connection is established, you can completely calmly turn on the music and listen to it through the car speakers.

The procedure for connecting to a TV is clearly shown in the video below. If you use a radio in a car, everything will be done exactly the same.

But this is only relevant for the USB model. If this output is not available, it is sufficient to use only the headphone input.

What can it be used for?

Its capabilities, in addition to listening to music from a smartphone or tablet connected via Bluetooth, are as follows:

This is the main thing that can do. Depending on the model, this list can expand, but the vast majority of them can only do so much.

What can be connected

Advantages and disadvantages

As for the advantages, it’s worth saying right away that such devices are very easy to use. In addition, many users like them for the following reasons:

Connects to almost all equipment that has Bluetooth. These can be various, even the oldest phones, tablets, navigators and the like. The adapter is completely undemanding.
Automatic connection with previously connected ones (not available in all models, but in most of them).
To connect, you can use any cables other than those included in the kit.
Easy installation. There is a magnetic base, so the device attaches very easily to metal surfaces.
Most of them have a function for voicing the state of the device, although only .
Small dimensions - does not take up much space. You can put it in your pocket.
Work without any glitches and other similar phenomena.

There are not many disadvantages of such adapters, but they still exist. The main one is that many drivers simply do not like the appearance of such a device.

Some people simply cannot stand the way it dangles when connected to the radio. However, considering all the advantages, this is a small minus.

Also, not everyone is satisfied with its cost. But all this is also subjective.

How much does it cost

As mentioned above, the price is about 5 US dollars.

To many, this amount seems too high for the simple reason that alternative options cost about 2 bucks.

We are talking, first of all, about, as well as a flash drive with Bluetooth. But, judging by the reviews, the adapter with AUX can last for many years.

Considering this factor and all the functionality described above, we can safely say that this device is worth the money.

Although, of course, if you don’t like its appearance and connection method, it’s better to look for other options. So the only question is where can you buy such a useful thing.

Where can I buy

Let's say right away that the best option is aliexpress.com and other similar sites.

Of course, the same equipment is also available in ordinary electronics stores, but it is still better to choose famous Chinese and other large foreign sites.

The reason for this is very simple - price. The same model in a regular store can cost $21, but on AliExpress it can cost $3.

The difference is quite noticeable!

Yes, but I don’t really want to pay that much money for a store.

Above we mentioned the EDUP EP-B3512 stereo receiver.

In Figure 5 on the left you can see it in a regular online store at a price of 589 hryvnia, that is, 22.5 dollars, and on the right - on AliExpress at a price of 185 rubles, which is equal to 2.7 dollars.

And the quality in both there and there, judging by the reviews, is completely the same. So feel free to buy adapters on large trading platforms.
