1, BSI M2 good 5.2 chip Bluetooth headset , BSI M2 real wireless in-ear active noise reduction Bluetooth headset, noise reduction for game calls. This is an in-ear noise reduction headset, Bluetooth 2 chip smooth no delay, 0.038S low, open cover flash connection, 10mm super dynamic speaker, support Type-c charging, charging pod 400mAh, maximum battery life of 30 hours, compatible with Apple, Android, Hongmond.
2. OkBluetooth headsets are basically Qualcomm chips. General Bluetooth headset is the Realtek chip, if you are not a Bluetooth headset enthusiast, some specialized Bluetooth headset domestic brands, like West Saint Bluetooth headset, pretty good, high configuration, low price, Qualcomm chip, support for aptx, touch, sound quality, battery life, fitness are very good, mainly cost-effective will be relatively high, 100 or so is worth starting.
3, QCC5125 low energy Bluetooth audio SoC, designed for mainstream Bluetooth speakers, stereo headphones and true wireless earbuds.
4,The difference between Bluetooth headset is mainly reflected in connection speed, transmission efficiency, power consumption and security. First of all, how about the Bluetooth headset with 5.2 chip , Bluetooth 3 is faster than the Bluetooth headset with 25.2 chip . This is because Bluetooth 3 in Bluetooth 25.2 chip Bluetooth headset on the basis of 5.2 chip Bluetooth headset Technology optimization makes the connection process between devices faster and reduces the waiting time for users.
2, the difference between Bluetooth 2 and 3 is: bandwidth, transmission distance, data transmission, power consumption, delay and so on. Bandwidth Bluetooth 2 supports a bandwidth of 2Mbps, while Bluetooth 3 supports a bandwidth of 4Mbps. Bluetooth 2 supports a maximum transmission distance of 160 meters, while Bluetooth 3 supports a maximum transmission distance of 300 meters.
3, data transmission rate: Bluetooth 2 uses a more efficient broadcast communication mode, which can achieve a faster data transmission rate. And Bluetooth 3 is oneStep optimizes this aspect of the technology and can achieve higher data transfer rates. Therefore, in scenarios where faster data transfer is required, Bluetooth 3 has better performance. 2 Security: Bluetooth 2 uses a more secure random address generation algorithm to prevent tracking and identification attacks.
4, the difference between Bluetooth 3 and Bluetooth 2 is as follows: low rate connection is different. The Bluetooth 3 version has a big advantage that it can transmit some low rate data, but this can not be achieved in Bluetooth 2, 3 the advantage is that even if the low power consumption and low rate signal will not affect the use.
5, the difference between Bluetooth 2 and 3 is that Bluetooth 3 strengthens the low-rate connection, Bluetooth 3 strengthens the encryption control, and Bluetooth 3 enhances the periodic broadcast. Bluetooth 3 enhances low rate connectivity Some data transfers cannot be passed in Bluetooth 2 due to low rates. Bluetooth 3 solves this problem, allowing low-power, low-rate signals to be used.
Demo model: Iphone 13 Bluetooth 1 function adds direction finding function and centimeter-level location service to Bluetooth 0 5.2 chip Bluetooth headset , so that indoor positioning will be more accurate 5.2 chip Bluetooth headset ; Bluetooth 2 adds the enhanced ATT protocol, LE power control and signal synchronization functions on the basis of Bluetooth 1, making the connection faster, more stable and better anti-interference.
Differences between Bluetooth Headset 1 and 2 Differences between Bluetooth headset 1 and 2 New includes LE synchronization channel: In the broadcast synchronization mode, unlimited audio receivers in the communication range can simultaneously listen to the shared audioFlow. Enhanced ATT: It is expected that the fast service discovery function will be applied in the next generation of Bluetooth audio technology to enable the rapid exchange of relevant service information between audio devices.
version is different. Xia Xin Bluetooth Headset 1 is a Bluetooth headset released by Xia Xin brand in 2021, which can reduce noise and ultra-long standby, while Xia Xin Bluetooth Headset 2 is the latest version of Bluetooth headset released by Xia Xin brand in 2022, with all the functions of 1, and on the basis of the original functions, reduce the delay and improve the sound quality, compared with Xia Xin Bluetooth headset 2 version. The price is different.
inBluetooth 1 does not define Bluetooth BR/EDR to include power control functions; Bluetooth 2 defines the bidirectional power control of BLE, which can be used to achieve a variety of application scenarios, helping to better reduce power consumption and improve device stability and reliability while remaining connected.
