Headphone is the assembly of two speakers that can be worn on your ear, it converts electrical energy to sound waves, which can be heard by individuals.
If the speaker is an audio device that helps a group of people to enjoy themselves to the full in the party; then a headphone is a tool for personal listening of media audio at any moment.
Generally, headphones are divided into wired headphones and wireless headphones. The below list shows the types of most welcome headphones nowadays.
■ Wired earphones
■ Gaming headphones
As we all know, the key components of electronic products play an important role in quality, performance, cost, testing, and headphones in no exceptions neither.
Of all key components for headphones, PCBA should be put in the first place. And what matters most in the PCBA is the chips and IC, which is the heart of headphones.
There are so many different brands and models of Bluetooth chips, which is too hard for you to distinguish. It is a long story to tell, in short, the best Bluetooth chip is CSR, which is a subsidiary of Qualcomm Incorporated since 2015. Other Bluetooth chip brands like Qualcomm, AROHA, BES, AMS, Jieli, Jianrong, BK, etc, are all getting quite hot because of its competitive price and good performance.
The Bluetooth versions are updating with the new technology that becomes much more smarter and powerful than ever before. And you are able to find a more detailed introduction of Bluetooth chips for Bluetooth headphones and TWS Earbuds 0n the other pages.
The rest key components are speakers, lithium-ion battery, housing, power adapter(if included).
According to audio experts, there are five aspects that lead to the good or poor sound quality of headphones and speakers.
● 10% Sound source
● 5% Decode (audio decoding and audio device decoding)
● 5% Audio amplifier
● 5% Audio transmission
● 75% Electroacoustic transformation (headphones or
speakers)
When it comes to batches of headphones manufacturing, below 3 points are going to decide the sound quality of headphones.
1.Speaker
No matter wired or wireless headphones, the speaker is one of the core hardware points of every audio product. The speaker used for both headphones and speakers in the market mostly is the dynamic speaker. Because the dynamic speaker stands out with its cost performance and adjustable sound quality.
Apart from that, there are other speakers too. They vary from earbuds to headphones, which based on different needs.
As for earbuds, you can also find there are dual-driver style, triple-driver style, and dynamic speaker and balanced armature speaker combo style.
In the light of raw material, the speaker can be divided into NdFeB (neodymium iron boron) magnet (white magnet) speaker and ferrite magnet (black magnet) speaker.
With its high sensitivity, the NdFeb magnet speaker is called the HIFI magnet speaker. You will find this kind of speaker is widely used in premium headphones.
2. Interior acoustic chamber of headphones
Just like the internal storage for mobile phones and computers, the interior acoustic chamber of headphone affects the headphones’ performance in every way: the frequency response, bass, express of sensitivity, distortion, etc.
Even if the best Bluetooth chip and the best speaker are equipped, the headphones are not going to have a satisfactory sound quality with poor inner structure.
The good interior acoustic chamber of headphones should meet the below points at the same time:
● Good air-tightness
● Enough space
● Good raw material
● Easy for assembly
With airflow get in and out of the interior acoustic chamber of headphones, the air pressure between diaphragms on the speaker and acoustic chamber will produce more living, powerful low-frequency sound.
3. Bluetooth Chip
Despite the fact that smaller and smaller gaps among different brand Bluetooth chips, as headphones manufacture, Go4Audio will choose the expensive ones for our high-end product lines without any hesitation.
You get what you pay for. For premium headphones, it’s a cost worth taking as you are going to have a high budget on tooling, speakers, and other material of headphones.
However, using Chinese mainland Bluetooth chips will be a smart choice when considering the cost of promotional items.
Surface treatment varies from headphones to headphones. Generally, DJ headphones prefer metallic, High-end ANC headphones like black rubber style, sports earbuds need to be lightweight…
Most of the time, for the headphones factory, below 4 different surface treatments are frequently used.
1.Rubber coating
The highlights of rubber coating are obvious: smooth touching feeling, exquisite matte looking, etc.
Though the regular use of rubber coating, the result of finished products can be different.
You can easily tell which one looks better in the below photos. Furthermore, the touch feeling differs in thousands of ways too. Send an email to Go4Audio to get more information.
2.Glossy finish
By improving the glazing and highlights of the surface of the headphones, the drawback of glossy finish is noticeable: easily involved with finger marks and dirty marks.
The glossy finish is mostly suited for applications where specific parts of on-ear or over-ear headphones are decorated. For example, decorating pieces of the ear cups, LOGO, etc.
TWS earbuds, however, are welcome to do glossy finish due to its small housing.
3.Metallic paint
Not like wired DJ headphones, we can improve the tactile sensation of surface treatment for headphones by using metal materials.
Misuse of metal material for Bluetooth headphones may result in signal interference. In this case, it will lead to the short operation distance, poor play performance.
Fortunately, metallic paint will help us to solve this issue more effectively. By combination with rubber coating, you will get a masterpiece rather than headphones.
4.Water transfer printing
Available in all kinds of different patterns, water transfer printing is mainly used for kids’ headphones, promotional gift headphones.
When it comes to quality, Go4Audio always keeps prioritizing and improving all the details in every testing program.
Before mass production, the reliability testing for new headphones proceeds completely in order to evaluate and confirm the quality of headphones.
Below testing procedures are necessary methods to ensure you will receive the quality-guaranteed headphones for your orders.
1. Bending Test for Headband of Headphones
2. Ear Cup Twisting Test / Rotation Test for Ear Cup
3. Adjustment cycling Test for Headband Arm
4. Pulling Test for Headphone Ear Cup
5. Pull Test for Headphone Arm
6. Ear Muffs Cushion Pull Test
7. Torsion Shear Test for Headband Arm / Ear Cup Offset Torque Test
8. Compatibility Test for headphones
9. Bluetooth Distance Test
10. Drop Test for Headphones
● Bare Unit Drop Test
● Individual Unit Drop Test
● Carton Box Drop Test
11. Electro-Static Discharge Test for Headphones
12. High Temperature and High Humidity Operation Test
13. High-Low Temperature Cycle Test
14. Cold Start and Cold Functional
15. Headphone Battery Life Test
16. Headphones’ Button Knob Life Test
17. Pull Test for cables
18. Cable Plug into/Pull-off Test
19. Swing Test for Cable
20. Salt Spray Test
21. Water Proof Test
22. Adhesion Test for Coating and Printing
23. Carton Box Vibration Test
24. Stacking Test
RoHS is a mandatory requirement to restrict Hazardous Substances for products sells in the European area.
As headphones manufacture, Go4Audio is responsible to ensure that all headphones components, sub-assemblies, parts, and final products comply with RoHS Directive 2011/65/EC.
For some supermarkets, retailers, and brand customers like ALDI, LIDL, etc, the below test report is an essential request.
REACH, SVHC, PAH, Phenols
CE is a safety and health requirement to guarantee that products are fulfilling the safety directives in the European area.
In terms of headphones, CE certification mainly including: LVD, EMC, RED (updated from R&TTE), ErP, etc. Being a headphone vendor, it’s our responsibility to provide customers with CE certified products.
It is worth having a great effort to find a reliable headphone supplier, not only capable of order following up but also be well up in all possible regulations related to headphones.
Choose Go4Audio, you will find yourself already freed from the trivial things, just leave us to do the rest.
Compared with Europe, the US had an easing policy in chemical compliance.
In addition, it’s also acceptable if the headphones supplier can provide the raw material testing report.
This method is not working when it comes to Europe.
CA Prop 65 is California law to limit the Hazardous Substances for products, which works for all products intend to sell at the California area.
Restriction of Heavy Metals also called 7P cause it mainly contains seven Phthalates: BBP, DEHP, DIDP, DINP, DNOP, DBP, and DNHP.
And of course, metal materials are excluded from the above Phthalates requirements.
When it comes to headphones, TSSA is used to verify the stuffing materials for both ear cups and carry case in Canada.
The headphones factory is required to upload the application and submit the payment annually in both Quebec and Manitoba.
In 10 business days, Quebec will send you the stuffing and upholstery permit.
Then, you need to print the stuffing information of headphone ear cups and registration numbers in English and French at the bottom of the color box.
All the consumer electronic products sell in the US should comply with FCC rules, the headphone is no exception.
Instead of just having silk-screen printed CE mark on the headphones, FCC claims to mark FCC ID on the headphones.
In this way, you will verify the FCC certification and testing report much more easily.
There is a detail that most headphone factories may ignore but which is very important: to list the lithium-ion battery (if have) warnings, FCC information, and FCC ID in the instruction manual.
This is a must requirement of FCC as well, which will have the end customers to remind the possible harmful interference of the products.
Just like CE in Europe, FCC in the US, C-tick in Australia, Canada has the RSS to regulate the effect of radio apparatus operation.
Actually, the issue of RSS247 is to substitute the appendix 8 and 9 of RSS-210 in 2015.
In the case of headphones, all the general Bluetooth headphones should be certificated with RSS247; while headphones with a transmitter, such as FM headphones, RF headphones (916Mhz and 2.4Ghz) are in the scope of RSS210.
After the testing is finished, it’s necessary to have the same operation regarding FCC.
For wireless TV headphones, the power adapter is the necessary accessory. And poor quality power adapter may cause potential safety hazards.
As a result, it is really important to verify the quality of the power adapter.
The most direct and easy way is to check the test report and certifications.
And the test regulations vary from country to country.
USA: UL
Canada: UL, cUL
Australia: C-Tick
Europe: GS
Japan: MIC
Korea: KC
When it comes to evaluating headphones, safety should be put in the first priority. And concern bout the safety of headphones, what matters the most is the lithium-ion battery.
For the buyers, how to verify the quality of lithium-ion batteries?
The most straightforward is to go with all the necessary certifications for the lithium-ion battery of headphones.
Here below is brief introductions about certifications of the lithium-ion battery.
IEC62133 / EN62133
The difference between IEC62133 and EN62133 is the standard of different areas. EN62133 is European Norm, while IEC62133 is the international standard specifies requirements of the lithium-ion battery.
Despite the above difference, the testing methods are all the same. Therefore, both of them are acceptable in Europe.
UL
UL is the basic standard for lithium-ion battery in North America, however, IEC632133 is workable for most of the buyers as well.
MSDS
MSDS is short for Material Safety Data Sheet, which is a must certification for all transportation of headphones with lithium-ion batteries.
UN38.3
Identification and Classification Report Transport of Goods
By simulating all possible and potential activities during transportation, UN38.3 emphasizes the safety of transportation. As a result, UN38.3 and Identification and Classification Report Transport of Goods are required not only in courier but also in sea transport and land carriage.
