What are the Bluetooth headphones with low latency that are suitable for listening to songs and play

Huawei, Xiaomi, Apple can do it.

There may be a certain delay in playing online games while wearing a Bluetooth headset.

Introduction to Bluetooth headset:

It is to apply Bluetooth technology to hands-free headphones, so that users can easily talk in various ways without the entangled wires. Since the advent of Bluetooth headsets, it has been a good tool for mobile business people to improve efficiency.

A Bluetooth laptop is a laptop with Bluetooth wireless communication function. The name Bluetooth has a legendary story. In the 10th century, the Norse princes competed for hegemony, and the King of Denmark stepped forward, and with his tireless efforts, the bloody war was stopped, and all parties sat down at the negotiating table.

Through communication, the princes released their suspicions and became friends.

Because the King of Denmark loves to eat blueberries, so that his teeth are dyed blue, he is known as the King of Bluetooth, so Bluetooth has become synonymous with communication. Now, a thousand years later, when a new wireless communication specification was introduced, people used Bluetooth to name it.

In 1995, Ericsson was the first to propose the concept of Bluetooth. The Bluetooth specification operates in the microwave frequency band, with a transmission rate of 1m bytes per second, a maximum transmission distance of 10 meters, and can reach 100 meters by increasing the transmission power. Bluetooth technology is globally open and has good on a global scale.

Types of Bluetooth headsets:

1. Mono.

Monaural Bluetooth headset is mostly wireless and small style, can be worn directly on the ear, the main function is to answer and hang up the call, can control the volume adjustment, mono ear Bluetooth headset some models also have dual standby, dual microphone, Liyin (can also be called noise reduction, can achieve a better call environment) and other technologies.

2. Stereo sound.

Stereo Bluetooth headset is based on the mobile phone supports the A2DP Bluetooth stereo protocol, only the mobile phone supports the A2DP Bluetooth stereo protocol, you can connect to the stereo Bluetooth headset to enjoy the Bluetooth headset**.

Stereo bluetooth headset has neckhang, headset, clip, glasses and other styles, and the neckhang and clip and other styles are wired bluetooth headset, the main function in addition to answering hang-up calls, you can also enjoy directly**, at the same time, part of the stereo bluetooth headset also has an LCD screen, not only can easily see the caller number, but also has the function of displaying song titles and lyrics.

3. True wireless.

The biggest difference between true wireless Bluetooth earphones and traditional Bluetooth earphones is that they use MultiplexLink multi-point wireless interconnection technology. As a brand-new concept wireless Bluetooth headset, it realizes the wireless connection between the left and right ears.

The external connection of these headphones is completely abandoned, and the left and right earbuds can work separately, so you can make hands-free calls under control. When you need to transform into a two-channel stereo, turn on the other earbud, and you can automatically form a two-channel stereo mode when you get close, so you won't be tied up by wires when sharing**, and it's more convenient to use.

Bluetooth headphones have a certain delay, because in the process of audio transmission on the mobile phone, there will be a delay, so whether it is a mobile phone or a computer, wired headphones are recommended, because there is no delay, but the most important point, if your headphones are good, when I didn't say those words.

It's no problem to listen to songs, there will be a little delay in large games, and I've used imported a few hundred yuan is no exception, and it will be better if your mobile phone is very high. However, Bluetooth is not yet comparable to wired headphones, which are directly connected, and whether the delay is delayed or not has nothing to do with headphones. The advantage of Bluetooth headsets is that they are wireless, and the life is longer, and I have used a few wired headphones, each with its own advantages and disadvantages.

Answer: In the case of noise, the Bluetooth bandwidth is relatively small, so if you transmit high-quality audio, there is a possibility of noise. 1.In terms of latency, all Bluetooth headphones in the world have delays at all times, which is impossible in any case.

Good headphones won't have delays.

Yes, but it didn't matter.

The range that can be used normally.

There is a delay.

Bluetooth still has delays, but due to the optimization of data compression technology and synchronization, the delay is difficult to detect in daily use.

In addition, the version of Bluetooth is more aimed at the improvement of connection speed, signal range and Bluetooth data broadcast range, etc., and does not have much improvement in the signal compression, latency and energy consumption of audio.

If you just use Bluetooth headphones to listen to songs and watch movies, then the latency is negligible, and if you need a Bluetooth headset to play games, there will be noticeable delays when the amount of audio data is large or the optimization technology of the product is not very good.

If you want to completely solve the delay of Bluetooth headsets, you can only wait for the continuous improvement of technology in the future.

Key features: Bluetooth is targeted at low-power devices, with a wider range and a four-fold speed increase.

Bluetooth will add indoor positioning assistance functions, and combined with Wi-Fi, indoor positioning with an accuracy of less than 1 meter can be realized.

The low-power mode has a maximum transfer speed of 2Mbps, which is twice as fast as the previous version.

The effective working distance is up to 300 meters, which is 4 times longer than the previous version.

Add a navigation function to achieve indoor positioning of 1 meter.

To meet the needs of mobile clients, it consumes less power and is compatible with older versions.
