The biggest surprise Apple has given this year is probably AirPods!
As a breakthrough, we will ignore the value of the face, but the price is really touching, the Bank of China actually reached 1288 yuan, is not standard, you need to buy it separately. This kidney is not enough to buy iPhone 7!
For the iPhone 7 that intends to cancel the headphone jack, but the AirPods design and price are not the majority of people who eat melon, today, China Power Hong Kong recommends a high-end Bluetooth headset solution based on CSR, let yourself DIY, your wireless Headphones are yours!
Based on the low-power Bluetooth CSR8670 chip application, this high-end Bluetooth headset solution uses CSR's unique TWS technology to achieve true stereo transmission of left and right headphones. CSR's unique CVC noise reduction achieves high quality call quality and CSR. Exclusive Aptx decoding technology. And with independent touch function, it can realize up and down music and playback pause, so you can easily enjoy a high-end earphone with comfortable wearing, good sound quality and no noise.
An Introduction
This solution introduces a true stereo transmission earphone for the left and right earphones, which is easy to carry and has no trouble with the associated line.
Based on the domestic market, the Chinese voice prompts are introduced to make it easier and faster for consumers to use.
Use CSR's exclusive GAIA AUDIO APP software to enable Bluetooth headsets and connected phones to take photos and SMS alerts.

Solution application segment
The CSR8670_X3 Bluetooth headset is a small device based on Bluetooth technology, which eliminates the connection between the speaker and the speaker, and is replaced by a wireless connection. The lightweight touch enables playback and pause and up and down, and the CSR8670 Bluetooth headset is used for high-definition voice calls. Suitable for business consumer groups, CSR8670 TWS features for true stereo transmission.

AirPods came out, and the Bluetooth headset market is heating up, but the recent radiation problems have also worried many people. We can only believe that in the future, headphones will become more and more intelligent, and there will be more possibilities.
A Small Computer System Interface (SCSI) connector, also pounced as [scuzzy" connector, is used for physically connecting and transferring data between computers and peripheral devices.
SCSI is the small computer system interface, which is an independent processor standard used for the system level interface between computer and intelligent devices (hard disk, floppy, optical drive, printer, scanner, etc.). It is an intelligent universal interface standard, which has the function of communicating with various types of peripherals. SCSI uses the standard software interface of ASPI (SCSI programming interface) to make the driver communicate with the SCSI adapter installed inside the computer. SCSI interface is widely used in high-speed data transmission technology on minicomputers. SCSI interface has many advantages, such as wide application range, multitask, wide bandwidth, low CPU utilization, and hot plug.
SCSI connectors type and interfaces
Centronics 50-pin connector: The Centronics 50-pin connector was once the most widely used SCSI connector. An external connector only, the Centronics is a SCSI-1 connector that looks the same as the Centronics cable that attaches to a parallel port printer. The Centronics 50-pin cable comes in male and female styles, and gender changers and cable converters are commonly available. Although used on older SCSI devices and external drive enclosures, this interface is no longer heavily used, due to its slow speed and short cable lengths.
High-density 50-pin connector: The high-density 50-pin connector is used on scanners and Jaz drives. It is one of the more common SCSI connectors and is usually used to connect SCSI-2 devices. Both ends of the cable are usually 50-pin male, while the sockets on the host adapter and external devices are 50-pin female.
DB 25-pin connector: The DB 25-pin or D Sub 25 is by far the most widely used connector. This connector is used for parallel and serial printers in addition to the many other devices available. Both ends of the cable are usually 25-pin male, while the sockets on the host adapter and external devices are 25-pin female. This cable is almost always an external connector.
Note: DB-25 SCSI CABLES are not compatible with and should not be used as serial or printer cables; serial cables and printer cables should not be used or attached to DB-25 SCSI adapters. You can short out the SCSI host adapter or the motherboard by using the wrong cable. Marking cables is the best way to avoid this.
IDC50 connector: The IDC50 is the most common internal SCSI connector. It is very similar to the standard IDE internal ribbon cable. The IDC50 SCSI cable is considerably wider then an IDE ribbon cable; in fact, it is usually the widest standard internal cable in use. This is a standard SCSI-2 10MBps internal SCSI cable. Many low-end cables have only two or three connectors, allowing for one or two devices to be attached to the cable. Seven-device cables are available, though they are often expensive and require a large case, as the cables may be four or five feet long.
High-density 68-pin connector: The high-density 68-pin connector is the SCSI connector of choice for SCSI-3 host adapters and peripherals. There is an internal ribbon cable version that looks very similar to the IDC50 connector. Many low-end cables have only two or three connectors, allowing for one or two devices to be attached to the cable. Seven-device cables are available, though they are often very expensive and require a large case, as the cables may be three or more feet long. Both ends of the external cable are usually 68-pin male, while the sockets on the host adapter and external devices are 68-pin female.
SCA 80-pin Micro-Centronics connector: SCA stands for Single Connector Attachment, a type of disk drive connector that includes connection pins for the power cables as well as the data wires. A SCA connector uses an 80-pin plug and socket to connect peripherals. This connector combines power, data channel, and ID configuration for fast installation and removal. SCA connectors are typically found only on high-end SCSI hard disks. The SCA interface was designed to provide a standard connection for systems using drives that can be hot-swapped. SCA makes swapping SCSI hard drives much easier than with traditional SCSI cables, plugs, and sockets. An adapter enables SCA drives to fit into standard SCSI enclosures.
SCSI SFF 8482: Also called "4x internal" by some vendors. This is a connector with the same form factor as SATA with the addition of a "bump" to key it specifically for SAS. (SATA drives can be plugged into SAS controllers, but SAS drives will not function with a SATA controller; hence, the necessity for the key bump on the connector.) As the name says, it's meant to be used internally, i.e., inside the computer case.
SCSI SFF 8484: Also called "32-pin" or "MultiLane". This is a high density connector usually intended to plug into the motherboard, controller, or backplane itself. Cables with this connector on one end usually have four individual SFF 8482 connectors on the other.
Serial Attached SCSI SFF 8470: Also called "4x external" by some vendors. This is simply a version of the SFF 8484 that's meant to be used with external (i.e., not located within the case) drives.
