How to tell if Apple s Bluetooth headset is using a Qualcomm chip

The Apple W1 chip was born with AirPods wireless headphones, which Apple said at the time were basically "reinventing wireless headphones." Apple's words have some truth, after all, AirPods are so popular today that even many Android fans have to admit that its revolutionary W1 chip really brings a seamless Bluetooth audio experience to iOS users.

Version.. BC4 is a little higher than BC3, which is equivalent to a step forward in technology. The ISS chip is not clear, but most of the Bluetooth chips on the market are.

There are still big differences between different chips, and there are more chips for headphones, including Qualcomm, Realtek, and Luoda. Among them, the headphones of the Qualcomm chip can support APTX encoding, with low latency and good sound quality, and Qualcomm has its own TWS

PLUS technology, the connection efficiency is much higher than that of other chips. The cost of the other two chips is very low, and the experience of using the headphones is very poor. So when choosing headphones, you have to look at which chip it is.

VKD233DS, VKD233DR --- important use in Bluetooth headsets, smart bracelets, smart wearables.

The gap between chips is actually very large. The mid-range market of headphones is basically using Realtek, Luoda, and Qualcomm. Realtek and Luoda are basically standard products below 400 yuan, with low chip cost, single chip, small size, and acceptable signal, but they all have disconnection, serious delay, large noise floor, navigation swallowing, slow response, unilateral call problems, etc.

The cost of these two chips is 2 yuan, and Qualcomm is 3 dollars, a difference of dozens of times. So due to the cost problem, very few Qualcomm chips are used. But the advantages of using Qualcomm chips are great, like the Shell Prince is a Qualcomm QCC3020 chip, which can support Bluetooth, support APTX decoding, and the stability and sound quality of the connection are much better than headphones using the other two chips.

Bluetooth chip refers to IC chip, Bluetooth module refers to PCBA semi-finished products that can communicate, and Bluetooth module is developed on the basis of Bluetooth chip.

Bluetooth module, serial port Bluetooth module and other products, as the name suggests, are semi-finished module products that realize Bluetooth function. Mainly by:Bluetooth chipand peripheral components, so as to form a product that can be directly used by users. Because there are many types of Bluetooth chips, many engineers don't know how to choose when choosing.

Therefore, to put it simply, the Bluetooth chip is just a part of the Bluetooth module.

If you choose audio + data transmission BLE, you can choose BT401

The Bluetooth module contains a Bluetooth chip, which has the wireless transceiver function of Bluetooth, and the Bluetooth chip is just a chip and is the core of the Bluetooth module.

Use Bluetooth module: rapid development, no need to do Bluetooth certification, the only disadvantage is high cost.

Direct use of Bluetooth chips: low cost, but difficult to develop, requiring special professional R & D personnel;

Therefore, if you are just doing Bluetooth application development, it is recommended to choose a reliable Bluetooth module, which is relatively simple to use, without considering those messy SDKs, etc., and you can do application development according to the interface, saving time and cost, and the performance is more stable. For low-power data applications, it is recommended to choose FSC-BT630, and for audio solutions, FSC-BT1006A can be selected.

You can open Apple's official ** on your computer and click on Technical Support.

After entering the technical support interface, enter the warranty status serial number query, and enter the serial number of the headset in the warranty status serial number query to check whether it is **. The specific query method is as follows:

2. After entering Apple's official **, click the technical support button at the top of the home page to enter.

You can see the serial number query that pops up, click to enter.

4. Find Apple's Bluetooth headset box, and at the bottom of it is followed by its serial number.

5. Enter the serial number marked by the box in the input box of the serial number query and click the Continue button.

6. At this time, after the page jumps, you can see the result of the query of the serial number of the Bluetooth headset.

Open the Bluetooth headset box There is a string of codes in the box! Then log on to the official website to check the warranty time! If it doesn't show this, it's a fake, and if the warranty doesn't match your activation date, it's second-hand refurbished!

You can log in to Apple's official website on your computer and check the serial number.

The zygote is real and the headphones are fake.

There is no need for identification, only the mobile phone with Bluetooth function can be matched with Bluetooth headsets.

Generally, there are two situations for the connection between a mobile phone and a Bluetooth headset.

First case: The operation steps of the new bluetooth headset and mobile phone connection:

The second case: the secondary connection between the mobile phone and the Bluetooth headset, the steps are as follows:

2. To make the Bluetooth headset in the power-on state, you need to press and hold the answer button of the Bluetooth headset.

3. Until the indicator light: blue light and red light flashes alternately and then releases.

4. At this time, the Bluetooth headset and the mobile phone will enter the match again.

5. After the Bluetooth model device is displayed on the phone, click OK to connect and use.

6. Note that the effective distance between Nokia mobile phone and Motorola Bluetooth headset is within 10 meters.

7. Some Bluetooth headsets need to enter the PIN code when matching, which is the password, which is generally: 0000 or 8888.

Bluetooth headsets don't seem to match this statement, the general mobile phone on the market, as long as it supports Bluetooth, you can theoretically use Bluetooth headsets, there may be miscellaneous machines for various reasons can not be used, but this probability is very small...

When choosing a Bluetooth headset, we must look for the specifications to see which specifications our mobile phone is suitable for, so as to choose a Bluetooth headset that matches our mobile phone. This is also the reason why some friends bought Bluetooth headsets, some support listening, and some can't. Some support stereo sound, while others don't.

As long as the comparison of these two specifications is clear, the Bluetooth headset you buy will be able to meet your basic requirements.

There is also a look at the built-in chip of the Bluetooth headset, the two more famous manufacturers of the production of Bluetooth headset chips are one is the British CRS company, and the other is the American Zeevo company. Among them, the Bluetooth headset chip produced by this company in the United Kingdom occupies a relatively large share of the market, which can reach about 80%. So if we buy the best brand of Bluetooth headphones, most of them are produced by this manufacturer.

Suggested choice: Jabra, Molang, Samsung, Nokia and other brands.

This class is different in design and concept, and it can be more perfect.
