Product Information

This new method of how antennas are used is called Angle of Arrival (AoA) and Angle of Departure (AoD). AoA determines the direction or angle, while AoD determines the distance of the signal.

This is a major upgrade from its predecessor, Bluetooth 5.0. With 5.0, devices can only determine how far a receiver is from the transmitter. However, with 5.1, the receiver can now pinpoint the location of your device from the one it’s connected with. Enhanced Attribute Protocol or EATT is the upgraded Attribute Protocol (ATT). EATT allows simultaneous parallel transactions between two Bluetooth devices.Bluetooth 5.2 features a new low-power codec called LC3. Audio codecs compress audio signals for faster wireless transmission. A lot of Bluetooth codecs have been developed through the years and the LC3 is the newest addition to that list. Who knew TWS earbuds would become so popular? When they were first released into the market, people didn’t seem too inclined to use these earbuds. The sound quality wasn’t great, and the risk of losing them was a bit too high. But today, we have various companies fighting for the top position in the TWS market. Step 1: Long press the multi-function buttons on both of them simultaneously until the LED lights on both sides blink in different colors alternately (usually red-blue). Today’s headphones connect fast and stable enough already. These enhancements are expected to improve these two areas further. Bluetooth 5.1 headphones are expected to connect faster and be more stable. However, the difference might simply be too subtle to be perceived fully. Advertising Sync Transfer Method 1.

GATT Caching stands for Generic-Attribute-Profile Caching. This form of technology plays a big role in creating and maintaining the Bluetooth connection between different devices. Firstly, the case comes with a magnetic design so that the lid stays shut even when you drop it. However, the four hours of playtime and additional 16 hours of battery life may not be enough for active gamers. Compared with wired headphones and even common wireless earphones, the most noticeable difference of TWS earbuds is that they are designed without any wires. Unlike wired earphones with wires, the tangle-free TWS earbuds have independently-individual left as well as right earbuds which can pair to each other automatically nearby. By matching successfully, the left and the right earbuds can switch to double-mode channel stereo, bringing you excellent sound quality. Moreover, unlike wired earphones which rely on the power from the mobile devices they are linked to, the TWS earbuds can be charged on their own built-in lithium battery cases with high performance. Low Energy or LE allows faster data transfer between two devices without the need for high power and high bandwidth. This was launched with the Bluetooth 4.0 version and continues to be improved on from Bluetooth 5.1 and onwards. Enhanced Attribute protocolNowadays the TWS Bluetooth earbuds have been the basic audio accessory for people who want to listen to music or make phone calls on the go. The reason why they are so appealing is obvious. After all, without any wires connection, these minimal earbuds bring both convenience and high audio performance to their users. Also, they almost have full-fit designs which make them be worn comfortably. With tangle-free design, the TWS earbuds also boast individual left and right Bluetooth-enabled channels as well as good sound quality. Basically, because of isochronous channels, devices with Bluetooth 5.2 can now support multiple devices. You can now connect your headphones to your smartphone, laptop, tv, and more at the same time.
