Headphones are a popular accessory for your phone. Almost all smartphone users have headphones. A wired headset is the most common, however, there is a wireless option. This article talks about how the wireless bluetooth headphones for your phone.
What it is
Wireless headphones are a headset in which communication with a smartphone is via bluetooth. There are bluetooth headphones with wires connecting the ears. Such models have one module that provides simultaneous sound in two headphones.
Another variety has no wires at all. Two headphones do not interconnect externally. And there are two separate parts. Such bluetooth headphones work separately, but if you connect them to the same network, they will work as a whole.
There are many options. For example, large bluetooth headphones are on the market. Such a headset is very comfortable worn on the ears due to its soft pads. Basically, this kind of headphones are designed for games, but can be used for ordinary purposes. Due to the large size, they are not very comfortable to wear in public places.
Destination
Before you figure out how bluetooth headphones work, let's consider what they are for and in what cases they are used.
Wireless is very convenient for busy people. You can listen to music or other recordings without fear that the wires will become tangled or the phone will drop out of your pocket. This can be useful for athletes or other outdoor activities where wires can just get messy.
Talking on headphones that work through bluetooth will also be comfortable, as you can insert one into your ear and hear both the interlocutor and the sounds of the environment.
Of course, such a headset is suitable for ordinary people, because wireless devices are superior to conventional ones with wires.
Device principle
Now let's see how bluetooth headphones work with a phone.
Wireless communication is such that signals are transmitted from the source to the receiver. In this case, the source is a smartphone. And the receiver is headphones.
When connecting the device for the first time, pairing between two devices is required. During this process, data is exchanged between the phone and the headset. They exchange unique codes that identify this device. Thus, the headphones are connected specifically to this smartphone.
Re-pairing does not occur, therefore, subsequent synchronization of devices occurs automatically, since the devices already have each other's data.
Signal Limitations
The question of how bluetooth headphones work is considered. However, this is not all you need to know about wireless. There are factors that affect this relationship and limit it:
- Distance. Obviously, bluetooth cannot work to pair devices if they are far apart. The devices can have different ranges, but basically the maximum distance is 8-10 meters.
- Barriers. It can be a concrete wall or radio emission. For example, the signal will be much weaker if there is a wall between the two devices. Also, for example, communication will be constantly interrupted if one of the devices is near the microwave. It emits radio waves that affect the synchronization of bluetooth.
Sound quality
How do wireless bluetooth headphones compare to regular ones? Here the differences can be significant.
For example, if the characteristics of the wired and bluetooth headphones are the same, then the sound will still be better for the former. The reason for this is just the bluetooth connection, which requires compression of sound for its best transmission. However, this difference is not too significant, so this can not be considered a big minus of wireless headphones.
Safety of use
Many people care about whether it is harmful to listen to music wirelessly. You should understand how strong the bluetooth signal is, and how it can affect a person.
Bluetooth communication cannot be carried out at a distance of more than 10-12 meters. From this we can conclude that the signal for such a connection is rather weak. For comparison, you can bring an ordinary cell phone. Its signal can spread up to several kilometers, but is also considered weak. Thus, the safety of using bluetooth headphones can be no doubt. Their signal is absolutely harmless at any time of use.
Connection Rules
How do bluetooth headphones work when connecting them to a device? You can connect your wireless headset to your phone, tablet, laptop, and even computer. But only if there is a bluetooth module. It can be purchased as a separate device and connected to the desired device.
When buying, first of all, you need to pay attention to the bluetooth version and check whether it works with a phone or tablet. If so, there will be no pairing problems.
The first step is to read the instructions for use, as important information can be written there.
You need to turn on the headphones with the corresponding button. Perhaps you should click another one so that the bluetooth signal for connection appears. Now on the device you also need to enable communication and click "Search for device." If the headset is broadcasting a signal, the name of the headphone to which you want to connect will appear on the phone. As already mentioned, the first connection requires pairing and may take some time. The word “connected” on a smartphone or tablet indicates that the wireless headphones are ready for use. Now it remains to turn on the audio recording and enjoy the music.
For individual headphones that are not wired, the actions will be slightly different. You need to start the signal on both headphones and connect to them from the phone. In this case, there will be two connections.
How to choose
What not to be mistaken with the choice, we recommend that you adhere to the tips:
- As already mentioned, the main factor is the bluetooth version, which should be suitable for connecting with this device. If the communication version is new, then the headset will be able to save battery power longer, since less power is required for synchronization.
- If you want, in addition to the wireless connection, the usual one is also required, then there are those models that have a cable connector, and there is the possibility of a wired connection.
- Type of headphone. There is a small headset, but there is a large one. The choice depends on the purpose for which the device is needed. If for ordinary listening at home or on the road, then it will be enough small. If headphones are needed for work or for games, then you can buy large ones.
- Battery capacity. It is clear that the larger the capacity, the longer you can listen to recordings and the better.
- The presence of a microphone. To talk on the phone with the headset connected, you will need a microphone through which sound will be transmitted. If conversations are excluded, then headphones without a microphone will do.
- Frequency. This parameter determines how many different sounds the headphones can play. To achieve maximum comfort, you need to choose a headset with a frequency range of 20,000 Hz.
- Sensitivity. This is the usual volume. The higher the sensitivity, the higher the sound volume can be adjusted.
- Resistance. This quality determines how the bluetooth headphones work and their overall sound quality. Those with a resistance value above 32 ohms will sound good.
Now you know the features of the fashion device.
