Music is universal. Who does not have a favourite song? Who has never gone to a concert by their favourite band? Most of the people who go out alone in the streets or take public transport usually wear earphones to listen to their favourite music.

But music is not the only audio content that exists. Radio, for instance, is very much in demand as some people listen to it to stay up to date on the news while going from a place to somewhere else.

And what about podcasts? They are becoming increasingly interesting and easier to listen to while walking in the streets or doing another tedious task.

However, these customised wireless earphones are more expensive because they are made for more intensive use. We all know someone who cannot live without earphones. In addition to listening to music, they always wear them to take calls.

They are perfect for business owners, for instance, who are always on the phone and need to be connected anytime. That is why, if your father is one of those people or if you know someone who might need these earphones, this is the perfect opportunity to surprise them. Make the most of their birthday, a special day you celebrate together, or simply give them a surprise just because.

These earphones are smaller in size but more solid. Their quality is higher, which can be seen in the price. That is why they are really good earphones for those who use them a lot. Do not think about it twice!

Of course, you can also customise these earphones as you want them to be. Nice!

FUNVOL customised wireless earphones for the most minimalists.

This is the perfect customised wireless earphones that can fit any pocket, hence their name “pocket earphones”. They are compatible with any mobile device and are high-quality.

These headphones are somewhere between those recommended for occasional use and those recommended for those who do use them every day and for long hours.

Our cases will protect your headphones from any fall, so you will not have to worry about it. Also, you can customise yours as you like: with a name or a text.

We do not customise them in colour because we do not use printed personalisation. We engrave them. The high-quality finish is suitable to surprise anyone on any occasion.

FUNVOL customised headphones: with or without wire.

At Funvol, we do not discriminate against anyone. So we try to have a wide range of products for you to find everything you need. Are you one of those people who are not used to wireless earphones? Here you have products perfectly made for you.

Customised headphones are a lifetime product, those that cover your ears so that you can listen to your favourite music very well. You can customise them with a photo in each ear, designing the most exclusive headphones in the world.

If you know that the person you want to surprise with a gift does not use earphones, this option may be ideal. You can choose between wired and wireless headphones. In other words, if the problem with not using headphones is that they fall off or seem uncomfortable, you can always choose wireless headphones, which are just as comfortable.

You have multiple options to give your audio content a boost! Contact us for more information.

Someone once asked the editor of the future design, what is the difference between wireless earphones and bluetooth earphones? Why are some earphones called Bluetooth earphones, some are called wireless earphones, and some are even occupied, called wireless bluetooth earphones?

In fact, there is an inclusive relationship between Bluetooth headsets and wireless headsets, and there is no direct affiliation. However, it should be noted that Bluetooth headsets can be wireless headsets, while wireless headsets are not necessarily Bluetooth headsets. The concept of wireless headsets is more extended than Bluetooth. Headphones are wider.

Wikipedia describes it this way:

A Bluetooth headset is a small device based on Bluetooth technology. It is only necessary to hide this lightweight device beside the headset without directly using communication devices (mobile phones, computers, etc.) to achieve free calls.

Wireless earphones are the middle wire replaced by radio waves. They are connected from the audio outlet of the computer to the transmitting end, and then sent by the transmitting end to the earphones of the receiving end through radio waves. The receiving end is equivalent to a radio.

Wireless bluetooth earphones include bluetooth earphones and infrared earphones.

There are three known types of wireless headsets: one is Bluetooth headset, the other is infrared headset, and the third is 2.4G.

Although Bluetooth headsets and wireless headsets are included, there are still differences between the two. Bluetooth headset is a low-cost and high-capacity short-distance wireless communication specification. The transmission distance usually depends on the technical support provided by Bluetooth. The basic communication distance is about 10 meters, the transmission rate is about 721kbps, and it works in the 2.4GHz frequency band. Support One-to-many data transmission and voice communication. For wireless earphones, the middle line is replaced by radio waves. It is connected from the audio outlet of the computer to the transmitting end, and then the transmitting end sends it to the earphone of the receiving end through radio waves. The receiving end is equivalent to a radio, and the working distance is within 7 meters. , Poor diffraction, if there are obvious obstacles (for example: people, large pets) between the infrared wireless headset and the transmitter, the answering of the infrared headset may be interrupted. The working distance of wireless Bluetooth headset can be about 100 meters, the working space is more free, and it has good music playback effect, and the confidentiality of communication is relatively strong, not only good sound quality, but also energy saving and lower cost.

After this combing, the editor of the future design believes that everyone should be able to distinguish the difference between wireless earphones, wireless bluetooth earphones and bluetooth earphones. You can refer to this article when purchasing to choose the style of earphones you want and need. .

Find a headphone factory for processing https://www.funvol.com/find-a-headphone-factory-for-processing/ https://www.funvol.com/find-a-headphone-factory-for-processing/#respond Fri, 20 May 2022 10:03:12 +0000 https://www.funvol.com/?p=2963 So many Bluetooth headsets choose to find OEM processing, and what are the reasons for these Bluetooth headset brands who are looking for OEM processing to choose OEM processing.

The post Find a headphone factory for processing first appeared on Funvol.

]]>
Headphones have always been one of the main products of mobile phone accessories. Since the advent of bluetooth earphones, the production of bluetooth earphones is a problem worth thinking about. Made in China is world-renowned. The production of bluetooth earphones is produced by manufacturers themselves or by earphone factories. processing. So many Bluetooth headsets choose to find OEM processing, and what are the reasons for these Bluetooth headset brands who are looking for OEM processing to choose OEM processing?

There are two reasons:

1. Cost saving

The production of a Bluetooth headset requires a lot of parts. The parts from the production to the product components to the finished product need a set of processes in a factory. Under the huge pressure of such a fierce competition in the Bluetooth headset market, it is necessary to be a brand, a market, a research and development, and a production factory. The tedious cost is too high, and it will distract the center of gravity of the enterprise. It is not as stable as single-mindedly, and the results will be higher.

The product processing is handed over to the earphone foundry to reduce the cost of staffing, and to have rich experience in technical processing to reduce mistakes, killing two birds with one stone.

2. Save time

An experienced headphone foundry is very fast in production speed. Compared with its own production, it is a plan that a Bluetooth headphone brand will choose to choose OEM for products to be launched as soon as possible. Saving time costs can save economic costs and improve economic benefits. If you want to build an independent factory brand, you need to invest a lot of money and talents. It is like crossing a river blindly and moving forward. You will lose energy in developing your own brand, and you cannot devote yourself to it.

So how an enterprise chooses its own Bluetooth headset foundry, mainly pay attention to the following points:

1. Choose from your own needs

Relatively speaking, the quality and service of brand earphone foundries should be more reliable, and consumers should have a deeper understanding of their brand. The disadvantage is that the price is generally higher. If you have a strong economic strength, you can cooperate with well-known brands and operate well. Profits are considerable. If your own economic strength is not very strong, you can choose some manufacturers whose brand awareness is not very high, but the quality control is good, and the products are also unique. Of course, when choosing a manufacturer, you should comprehensively consider the aspects of research and development strength, production strength, channel construction, and after-sales service. Before deciding on cooperation, it is best to go to the factory for on-site inspection.

2. The hardware equipment strength of the headphone foundry

First of all, look at the hardware strength of the earphone foundry, and the hardware strength of the earphone foundry depends on the factory area, production equipment, testing equipment, number of employees, etc. The strong manufacturers generally have a relatively large factory area, many production lines, Adequate grass-roots staff and advanced testing equipment can ensure product delivery and product quality.

3. The soft power of headphone foundries

The soft power of the earphone foundry mainly pays attention to the research and development strength, brand strength, channel development and management and control capabilities, and after-sales service of the earphone foundry. A powerful headphone foundry generally has an excellent R&D team, with a large number of products, and the speed of new product updates is also fast. For the cooperative dealers and agents, it is suitable for the market. Personalized, beautiful and cost-effective product updates Faster, the better the product sells, the less the phenomenon of overstocking, the faster the capital turnover, and the better the profit.

In addition, manufacturers with strong brand strength have high product popularity, and consumers have higher acceptance of the products, and the required marketing and promotion expenses are relatively less. In addition, strong manufacturers have relatively better control over channels, and there will be less occurrence of cross-selling in the market. For dealers and agents, the rights and interests are guaranteed.

Shenzhen FUNVOL Electronics Co., Ltd. is the professional audio company and brand in the industry with sound quality technology as its core advantage. quality of life. Provide Bluetooth speaker, headset distribution and wholesale, Bluetooth speaker research and development, Bluetooth speaker OEM (ODM/OEM), media and other services.

What chip is good for bluetooth headset? https://www.funvol.com/what-chip-is-good-for-bluetooth-headset/ https://www.funvol.com/what-chip-is-good-for-bluetooth-headset/#respond Fri, 20 May 2022 09:50:07 +0000 https://www.funvol.com/?p=2960 At present, the main chip brands on the market can be divided into four categories: CSR and Loda, Jerry, Chong Jie. Apple, SONY and Huawei, all developed their own chips.

The post What chip is good for bluetooth headset? first appeared on Funvol.

At present, the main chip brands on the market can be divided into four categories:

1. Apple’s self-developed H1 chip, used in AirPods series products, supports voice operation function, can call out the Siri of mobile phones, and has excellent performance in terms of delay.

2. Qualcomm series chips, which occupy the mid-to-high-end chip market, have unique aptx technology, efficient coding, more details of sound retention, and greatly improved delays. The representative models are QCC3020, CSR8675, etc.

3. Taiwanese manufacturers; Luoda, Hengxuan, Realtek, etc. Among them, Luoda is a brand with a large market share in the current Bluetooth audio market, with representative models such as 1536U, which is known as the “Shen U” of Huaqiangbei AirPods; the next is Hengxuan BES and Ruiyu, currently many domestic Large manufacturers are using the BES23 series for development.

4. Manufacturers such as Zhuhai Jerry and Zhongke Lanxun produce chips that are mostly found in Huaqiangbei AirPods, with huge shipments.

The CSR solution is used more on high-end Bluetooth headsets, with stable sound quality, 5-band tuning, and low power consumption. The disadvantage is that the noise floor is more difficult to control. Many manufacturers develop this solution, but usually the noise floor is not well controlled.

Texas Instruments (TI) and Zhuhai Actions program, Bluetooth headsets are not used much, and the sound quality is not bad. And the Actions solution has a very big advantage, the noise floor of the chip itself is super small. The Bluetooth headset developed on this platform can achieve almost zero noise floor with technologies such as filtering noise cancellation and algorithm noise cancellation. For example, the HIK X1 Bluetooth headset adopts the Actions solution, and the noise floor is very small.

Luoda is mainly used to imitate Apple headphones, the sound quality is acceptable, but some functions cannot be customized, which is relatively rigid. Jianrong and Jerry needless to say, listen to the series. 19.9 free shipping is it.

But whether a Bluetooth headset product is good to use, you can’t just look at the chip solution. Peripheral circuits, tuning, and software debugging are all indispensable.

The principle of ANC noise-cancelling headphones https://www.funvol.com/the-principle-of-anc-noise-cancelling-headphones/ https://www.funvol.com/the-principle-of-anc-noise-cancelling-headphones/#respond Tue, 17 May 2022 16:00:50 +0000 https://www.funvol.com/?p=2932 As we all know, Bluetooth headsets are mainly divided into passive noise reduction and active noise reduction in terms of noise reduction.

The post The principle of ANC noise-cancelling headphones first appeared on Funvol.

As we all know, Bluetooth headsets are mainly divided into passive noise reduction and active noise reduction in terms of noise reduction. Most of the methods on the market are passive noise reduction. From 2022, it should be the market of active noise reduction, that is, the trend of ANC noise reduction headphones, so Bluetooth headset manufacturers will elaborate on the principle of ANC noise reduction headphones today, so that everyone can better understand ANC active noise reduction headphones.

Noise Cancelling Headphones

Active noise reduction can generally be subdivided into Feedforward ANC (feedforward active noise reduction), Feedback ANC (feedback active noise reduction) and Hybrid ANC (hybrid active noise reduction, which is actually feedforward plus feedback). Each of these methods can be divided into adaptive (adaptive) and non-adaptive (non-adaptive) ANC. Generally speaking, adaptive ANC can only be digital (digital) control. However, under non-adaptive ANC, it can be divided into analog (analog) and digital ANC. A long time ago, because the DSP chip was not powerful and did not support real-time complex calculations, etc., there were only analog ANC headphones on the market, that is, the calculated ANC controller was implemented with components such as capacitors, inductors, and resistors. Now with the rapid development of DSP chips, ANC controllers can be digitized. There are many advantages, such as the strength of ANC can be adjusted, etc. Some headphones, noise reduction capabilities can be controlled by the mobile phone APP. Currently on the market is basically the world of digital ANC headphones.

Active noise reduction principle:

Active noise-cancelling headphones are much more complicated than ordinary headphones. A noise-cancelling module needs to be built into the headphones. It contains a microphone to receive external noise, and then through the calculation of the internal circuit, the headphones can play music while adding and The sound waves of the outside noise “invert”, thereby canceling the outside noise.

Here we mainly talk about active noise reduction. Active noise reduction is divided into three types of noise reduction: feedforward noise reduction, feedback noise reduction, and feedforward and feedback combination. Feedforward and feedback noise reduction Feedforward noise reduction is to design the microphone on the outside of the headset away from the speaker, while feedback noise reduction is to design the microphone near the speaker. Feedforward noise reduction is easier to implement, while feedback noise reduction can collect noise information that is closer to what the human ear hears, but the microphone may be affected by the sound of the speaker, which requires higher algorithms.

At present, most of the relatively high-end noise-cancelling headphones combine passive noise-cancelling, feed-forward and feedback noise-cancelling designs, which have a very good effect on noise shielding and elimination.

Due to the complex structure and working principle of active noise-cancelling headphones, the price is generally much higher, and most of them are at a price of 1,000 yuan or more. However, the shortcomings of active noise reduction headphones are also obvious. Since the sound unit will emit additional sound waves to cancel the noise, there will still be differences in the sound quality performance, and the sound details will be lost.

However, with the development of Bluetooth headset manufacturers’ technology, the current active noise reduction headphones also have quite good sound quality performance, and their applicability is broader than passive noise reduction. Although this technology has been developed for decades, there is still a lot of room for improvement. Conditional friends suggest that it is better to choose active noise-cancelling headphones.
