Bluetooth receiver: models, specifications, purpose. Bluetooth receiver: models, specifications, purpose Let's take a closer look

Hi all!

At home, the music center LG FB166 has been working properly for several years now. In terms of sound quality, it suits me perfectly. The only thing that upsets is the support of audio formats (MP3, WMA, AudioCD). A similar situation with the car radio, unpretentious Sony. Since there are several good portable players available, my entire music collection is mostly in lossless FLAC format. You have to convert music for both sources, which is not very convenient and takes a lot of time. There was a need for a small, portable intermediate device that could be connected to a music center or car radio and transfer music through it in any audio format, without the need for conversion. For this purpose, this device was purchased. Let's take a closer look at it together with you, and at the same time connect it to the music center and car radio.

Specifications

Box

Small cardboard box.

Unboxing

Inside the box there are two inserts, one of which contains the receiver itself, the other contains accessories.

Equipment

The kit includes a USB - MicroUSB cable for charging the device and a 3.5 mm AUX cable.

There is also a voluminous manual in Chinese and English.

Appearance

The device looks very simple. The top and back parts are made of tactilely pleasing rough plastic. End edging made of ordinary plastic with notches. The assembly is good. There are no backlashes, cracks and creaking during compression.

On the front side there is a button for connecting and disconnecting, a microphone hole and an LED indicator.

The back side is empty.

On the bottom, there is also nothing.

On top are two 3.5 mm audio outputs and a microUSB connector for connecting a charger. You can connect two devices at the same time.

Dimensions

The receiver is quite small.

Pairing with an audio source

To pair with a source, you need to activate the Bluetooth connection on the source, and on the receiver, hold down the button for a few seconds (about 5 seconds) until the color indication. The connection happens automatically.

When the device is connected, the blue LED on the front panel flashes.

Communication is secure. No interruptions or stutters. The radius in a straight line, without obstacles, is about 15 meters (the receiver is in the car).

When the connection is broken or the Bluetooth connection is turned off on the source, in order to save battery, after a while the receiver automatically switches to standby mode. It works as follows. If the lack of connection is not too long, 30 minutes, then when both devices fall into range, the connection occurs automatically. If the lack of connection is long, about an hour, then the receiver needs to be “woken up” by pressing the button.

Battery

Full charge, charger 5V, 1.5A about an hour. During charging, the indicator lights up red. Turns off when charging is complete. You can listen to music while charging.

Playback time (according to the car BC, travel time) 9 hours, which is close to the declared manufacturer.

Connecting to devices

A short video showing the work.

car radio

Connecting to the car radio through the AUX input. Car audio is pretty basic. In the car, the music for me is more for the background. Sound source, ASUS ZenFone 2 smartphone. I like the sound, even with budget speakers and the same head. The sound in my opinion is even better than MP3 from a flash drive.
In music mode, pressing the button - Pause / Play. Tried in two players TTPOD and Poweramp, switching tracks by double or triple pressing the tracks does not work.
In addition, there was a speakerphone for calls and navigation. In the talk mode, pressing the button - Answer / Hang up.
On a smartphone, using standard tools, you can separately adjust the volume for music, system notifications and incoming calls. With incoming calls and notifications, the music pauses.

From an old bluetooth headset for a 3.5mm jack audio jack.

I think it's no secret to anyone how a bluetooth headset works.
This article describes how to make a more versatile device for wireless music playback while maintaining the functionality of a headset.

This homemade product will be useful for drivers (for making and receiving calls through the standard audio system), for listening to music through an AUX connection or on headphones.

We will need:
1. Bluetooth headset
2. Audio connector 3.5mm jack
3. Pair of wires
4. Heat shrink
5. Super glue

From tools:
1. Soldering iron

Step 1.
We need a 3.5mm audio jack. You can get it from old equipment, as I did, or buy it at any radio store.

Step 2
We carefully remove the speaker from the headset and solder the wires from it.

Step 3
We place our 3.5mm jack audio connector in the most convenient way and solder the wires according to the pinout and glue it with super glue.

Pinout

Since the headset gives out a mono signal (on one channel), we will combine the right and left channels into one, soldering them together with wires. The photo shows that two red wires are soldered to one channel. One goes to the headset, and the second connects the right and left channels. Now the mono signal from the headset will go to both channels. If this is not done, then only one side will play when listening to headphones, as with any audio system.

Step 4
Now we put on heat shrink to isolate contacts and aesthetics of appearance.

This completes the upgrade. Connect headphones or AUX cable and check.

The built-in battery will allow you to work not for a long time. Therefore, take care of the additional power supply of the receiver for its continuous operation.

Video recording of step-by-step assembly and operation of the device for review.

Hi all!

I want to write my review about the receiver, which allows you to transfer sound from your phone to wired headphones. It can also be used with speakers, and the sound can be transmitted from a computer or laptop.

This product has already appeared here, but I had little information, so I am writing my review.

The reason for the purchase is simple, the 3.5 audio port on my phone loosened up, self-repair helped, but not for long, for a full repair you need a soldering iron, which is not there, and I don’t want to pay a lot of money to the masters for repairs, since I know that repairs are cheap , but the prices are breaking everywhere.

On 10/14/2015 the goods were sent to me, the cost is 174.95 rubles, on 11/02/2015 I found the parcel in the mailbox.

How it works? We insert headphones or speakers (3.5 jack) into the receiver, we insert the receiver into a USB port that provides power, I powered it from the phone via OTG, it can be from USB speakers if any, or from a computer, in general it depends on the situation. In my case, I want to find a portable battery.
On the phone, turn on BT and look for the YET-M1 device, contact it, if necessary, enter the code 0000.

We turn on the music, and we are glad that everything works.

When the receiver is connected to power, a female voice broadcasts something from the headphones, sort of like pute use mode.

Alas, there are drawbacks. It's noise in the headphones. While listening to music, nothing is noticeable, but when nothing is playing or the beginning of the track is empty, then noise is heard, like a record or an old cassette tape, and sometimes all sorts of clicks and dials, like on old telephone lines. But it's not too loud, it doesn't bother me, now I can watch movies on the train, tk. my BT Logitech open type lose all sound.

The declared 10 meters do not reflect reality, when connected to a laptop, and moving the phone 4 meters forward, the sound was interrupted, the phone was flickering and barely worked. 1-2 meters, everything is fine, even more so in a pants pocket.

It is possible to turn wired headphones or speakers into wireless ones, to varying degrees.
+ No problems with pairing, everything picked up and worked right away.
+ No massive drop in sound quality. Movies look the same as before, perhaps a little more noticeable deterioration in music.
+ So far I have not noticed a sound lag when watching a video.

They do, but not terribly much. It is noticeable mainly when there is no sound, or everyone is silent in the film, in general, from scratch.
- Still, the sound quality is a little lower, I have Sennheiser IE4 headphones, the native sound is better. Maybe it's all about the same background. However, in general terms, everything is not bad.
- This receiver model is not the most compact, I'm waiting for another, smaller one. This one is about the size of a fat flash drive.
- In conjunction with OTG, there is a danger of damaging the phone's microUSB port. And the design is not the smallest.
- You can connect with a portable battery, but you need to look for a small and suitable option. The fact is that I have a 2-cell battery, but it does not charge either my BT headphones or power the receiver. Apparently the fact is that they consume less than the phone when charging, the battery thinks that it is not charging anything and decides to cut off so as not to work idle.

And yet, those who have a situation like mine will most likely be happy and they will not be stopped by all these minuses.

Later there will be two more reviews for analogues, a smaller receiver and a receiver with a battery.

UPD. 03.11.2015
- On the train, sometimes there is a sound, like when a mobile phone rings next to an old music column. I didn’t observe this on the street, apparently there are too many different devices around with different networks, and the receiver catches something left. However
