The volume button

In order to avoid the tedious process of pressing too many buttons, bluetooth earphones usually use the previous one, the next one and the volume plus or minus keys in one key. Volume - one press is to reduce volume, long press or double press is the previous song. Different headphone buttons work differently.

"How to connect bluetooth headsets" "how to use bluetooth headsets" some authentic headsets will come with a manual, describing the use method and function. Before use, you still need to take out the manual and read it carefully to learn how to use the headphone function.

What should I pay attention to when using headphones?

Precautions for use of earphones

Matters needing attention when using Magnetic Wireless earphones.

Because headphones are closer to the inner ear tissue than normal external noise; All users are required to take necessary protective measures. Studies have shown that pleasant music causes less hearing damage, but long-term exposure to high-decibel sounds, either music or noise, can cause hearing damage. Noise-induced sensory nerve hearing damage occurs in the inner ear, when high-energy sound waves shock fluid in the cochlea, overstimulating and causing cell death. Hearing damage can build up over time, and long-term exposure to noise, even for a short time, can cause hearing loss.

Research published in the journal of the American medical association in 1998 and conducted at shanxi medical university in China showed that prolonged exposure to high noise levels had a negative effect on hearing.

When using Wireless Sports Earbuds in the street, in addition to the hearing impairment caused by the need to increase the volume, it is easy to lose the alertness of users to peripheral sounds and increase the chance of danger. Children should not use earphones.

Ways to improve your headphone space

Ways to improve your headphone space shared by Wireless Sports Earbud factory.

The spatial aspect of the headphones has been unsatisfactory (the other is low frequency), which should be said not to be the drawback of the headphones, but the features of the headphones. A headphone is a pair of small speakers on either side of the head (which is how the headphone was originally created), and the sound field is naturally in the head. Modern recordings tend to use multiple microphones, and there are few single point recordings and head recordings, which is another reason for the poor spatial sense of earphones. In order to improve the "head-to-head effect" and make the earphone hearing sense more in line with people's physical and psychological characteristics, spatial simulation is required. There are three main methods: crossfeed, in-front localization and surround. The first two methods are used in two-channel stereo system and surround sound is used in multi-channel system.

1. Each feed

Such as AKG K1000, Precide Ergo, Jecblin Float, they use small sponge to keep unit outside the ear at a distance, so that each ear can hear the voice of the other side of the unit, the feed each other with the voice of the auricle positioning function, sound field will be more, depth, K1000 was able to adjust the Angle of the unit to adjust the space effect.

2. Positioning forward

For example, Vivanco SR2000IFL, the general earphone unit directly emits sound to the listener's ear, Vivanco SR2000IFL unit is placed in front of the ear to simulate the way of sound transmission during daily listening, the K1000 also has this function, and some models of SONY and STAX also adopt this design.

3. Surround sound

3-1 four-channel system

For example, AKG K290 has two drivers per side unit. When fed to its four-channel signal, it can get a better sense of space than two-channel signal. The specific effect is related to the design.

3-2 Sennheiser Surround headphones

Its surround sound part is independent and hangs on the shoulder. The main channel earphone is still the traditional way and the head can be moved at will. Now there are products for PC.

3-3 simulate surround sound

The surround sound effect is simulated by surround sound processor. The earphones buy from Wireless Sports Earbud wholesale use traditional dual-channel earphones, and there are many products in the market using this technology. Sennheiser has similar products, such as Lucas and DSP360; Dolby has a new Dolby Headphone based on the Dolby ac-3. These systems require a higher-end earphone fit with an excellent acoustic design to get the most out of them.

3-4 vibrating earphone

Panasonic has this product, which USES a vibrating unit that vibrates with a low-frequency signal to make it feel low-frequency, which is actually a way to improve the way headphones can only hear and not feel low-frequency. But people experience low frequencies through their gut and uhf through their skull, which is a little bit of a thirst quench.

Is it necessary to headset down? Headphones fever must understand science

Is the earphone cooker necessary? Headphone fever must know science shared the Bluetooth earphone supplier.

If you are interested in the sound quality of earphones and you are a headphone enthusiast, the first thing you should do after getting a new earphone is "the earphone cooker". But is the earphone cooker necessary?

The purpose of the cooker is to make the horn aging rapidly and steadily. In fact, it is in the diaphragm of the cooker. The mechanical conformity of the diaphragm of the new earphone is poor, which leads to a large distortion. It is a very easy concept to understand, and the same as the car, the newly bought car brake sensitivity is low, brake has not reached the best state, use a period of time after the brake pad after running, brake will slowly reach the best. Stereo bluetooth headsets and wired headsets are necessary for the cooker.

The earphone cooker is a difficult technical work, to control the duration, volume, use music type and sound frequency. Choose a different music depending on whether the headphones are heavy bass or human. Bad control means the sound quality can't reach the ideal state. Different sound quality and proficiency of cooker have different methods of cooker, which makes the cooker more simple, 1. Fast cooker, 2. Natural cooker, 3. Software cooker. According to the different sensitivity and impedance, the voltage output playback device should be selected to carry out. Music should also choose lossless music, such as FLAC format music. The original CD record is copied with lossless encoding audio format, which can reach the frequency range of the original song. After the system of the cooker, voice expression will be more delicate, clear, mellow natural.

1. Fast cooker

Rapid pot machine, in a short period of time to achieve the ideal effect, can use noise to white noise, pink (for example, when no signal on the radio voice, loud sound like sharp is white noise, the sound is delicate pink noise) is another kind of conventional music looping in stages to warm, probably can be completed in a week. At present, the music suitable for earphone cooker has [(1) dukou - CAI qin, mezzo-soprano and low frequency test (94) unplugged version of hotel California, three frequency balance, clear details, feel the sound field) and so on.

2. Natural cooker

Simple understanding is not deliberately choose music pot machine, listen to their favorite type can, choose small and medium volume, avoid electronic music, a long time on the ear, sound quality will slowly run into the ideal state.

3. Software cooker

In order to make the cooker simpler, many players have launched the special software for the cooker at present, and it is fully automatic, with fixed non-destructive music, the software automatically controls the volume and duration, and the intelligent cooker is more convenient. At present, cool dog music, cool I music player App support software cooker.

Is it necessary to use earphone? After reading the above introduction, it can be understood that earphones are still necessary to use the earphone to make a better sound quality. However, very low-end earphones have no value of using the earphone, which wastes time and energy and will not improve the sound quality.

The following recommend several kinds of headphone bluetooth headphone with good sound quality and high cost performance ratio, shenzhen tianyun electronic technology co., LTD. 's own open-die earphone, novice cooker and the best choice for pursuing sound quality.

(1) appearance and sound quality combination, high quality CSR bluetooth chip transmission, ear type design perfect tuning.

(2) sound quality and comfort, practical combination, CSR bluetooth 5.0 high-performance chip, support tf card passive playback, hd sound quality, fashion choice.

Why don't headphones and speakers replace listening systems?

Why don't headphones and speakers replace listening systems?

In-ear Metal Earbuds manufacturer shares that there is often a high level of concern about microphones and voice recorders, but a lack of attention to the monitoring system.

Listening system is another pair of ears of musicians, our music works must be based on it as a reference to achieve, its importance can be imagined.

Why don't headphones and speakers replace listening systems?

What are good listening environment conditions?

1. Stable balance from treble to bass

Never too strong or too weak in either range, try to keep it as smooth as possible at the same volume.

2. Easy to find flaws resolution

Small noise and tonal differences are not drowned out by other sounds and can be clearly judged.

3. No exaggeration or short stature

It can correctly judge the "size" (three-dimensional sense, depth) of the sound field built after mixing all the materials.

Why don't headphones and speakers replace listening systems?

Recording studio for signal monitoring tools are "listening speakers" and "listening headphones" two categories. Due to its characteristic of faithfully presenting the original appearance of sound, it is mainly used for sound playback in the recording studio to provide audio reference for producers. It is not suitable for listening to music, and its real mission is to find defects and problems in audio signals timely and accurately. For this type of device, we look at factors such as the accuracy of sound reduction, auditory fatigue, and power.

How to identify the sound quality of bluetooth headsets?

How to identify the sound quality of bluetooth headsets? 

Wireless Sports Earbud supplier shares that to understand the sound quality of bluetooth headsets, we need to understand the following concepts:

A2DP: is a bluetooth audio transmission protocol, using the chip in the headset to stack data, to achieve high definition of sound. At present, most bluetooth headsets in the market use A2DP transmission protocol.

(2) apt-x: is an audio digital compression algorithm, mainly used in the professional audio field, to provide high-quality audio, some high-quality ear support this algorithm

(3) LDAC: by SONY development of high quality audio codec, qualcomm's apt-xhd as the main competitor.

(4) LHDC: high quality bluetooth audio codec protocol.

5. SBC: the general audio encoding format, bluetooth transmission does not support AAC, aptx when SBC transmission, now 80% are in this format.

6 AAC, audio encoding format, when bluetooth support AAC file, mobile phone also support AAC transmission, sound quality is much better than SBC, ordinary people can hear the difference, currently qualcomm CSR mainstream chip is supporting AAC format transmission.

Although the current bluetooth version is limited by the transmission capacity of the A2DP (the SBC can only provide a maximum bandwidth of 328Kbit/s at 44.1khz), the 100% restoration of audio through bluetooth cannot be achieved (CD sound quality requires a bandwidth of 1.41mbit /s). But if instead of using SBC, some more advanced compression technology can be used to compress audio and then transmit it through A2DP, then the sound quality can be greatly improved.

The structure and environment of the headset and the distance between bluetooth devices may affect the bluetooth signal and cause the sound quality distortion.

From the above, we can understand that the sound quality of the headphone will be affected by bluetooth transmission. Only by purchasing high-quality bluetooth chip and cooperating with decoding software and equipment, can we get a very good effect.

Does the wireless transmission of bluetooth headset affect the sound quality?

Does the wireless transmission of bluetooth headset affect the sound quality?

Bluetooth Earphone supplier shares that in this era of rapid development of science and technology, wireless intelligent devices emerge in endlessly, whose purpose is to bring convenience to our life. Bluetooth was first developed by telecom giant Ericsson in 1994 as an alternative to RS232 data lines. No wires, multiple devices, mobile phone, computer data transmission, computer peripherals, printers, home appliances, headphones, cameras, cars and so on.

Bluetooth is a wireless technology standard that USES UHF radio waves in the ISM band of 2.4~2.485GHz to achieve short distance connection between devices. Traditional wired earphones transmit audio data by wire, while bluetooth earphones transmit audio data by radio waves, so many people will have a question: does listening to music by bluetooth earphones affect the sound quality?

The difference between the bluetooth headset and the wired headset is that there is an additional bluetooth module and battery, and the connection wire is removed. Bluetooth protocol has undergone several versions of evolution and upgrading. In the previous version of bluetooth protocol, due to the limitation of transmission efficiency, it cannot reach the transmission speed required for music listening, so it is often used for communication, receiving and making calls.

Regardless of the speaker unit, the most important is the bluetooth chip, which determines the quality of the transmission of sound. A good bluetooth chip can support better audio decoding technology. Our factory mainly adopts qualcomm CSR chip, which supports double channel stereo codec and earphone products that support apt-x, with high quality transmission and low distortion.

At present, the popular high quality bluetooth audio compression algorithms include aptX/ aptx-hd, LDAC, LHDC, etc. AptX is the technology promoted by CSR, which has become the proprietary technology of qualcomm chips after being acquired by qualcomm.
