Contact our official customer service centers for a list of supporting phone models. Customized features such as DeepX 2.0 Stereo Sound Effects, Google Fast Pair and Find My TWS work only with compatible vivo phones.Compared with vivo TWS Neo, vivo TWS 2 ANC can increase the amount of transmitted data by up to 25% in a complex environment, as tested in vivo laboratories.Compared to AAC/SBC codec, aptX Adaptive high definition codec can theoretically increase the amount of transmitted data by up to 50%.

Regular true wireless earphones are those with AAC/SBC codec.Compared with traditional A2DP Bluetooth protocol, QHS high bandwidth transmission technology can increase the theoretical bandwidth from 3Mbps to 6Mbps, which is an increase of up to 100%. Traditional Bluetooth refers to the A2DP Bluetooth protocol.Immersive DEEP-HD Audio can only work when paired with vivo phones that are specifically optimized.Compared with vivo TWS Neo, the performance gain is up to 148%.

Wind noise cancellation performance as tested in vivo laboratories.

Actual noise cancellation effect may vary depending on the shape of users’ ears, size of the ear tips, how the earphones are worn and ambient noise situation.

40dB is the maximum level of noise cancellation as tested in vivo laboratories.

Multiple advanced technologies work together to offer an ultra crisp and smooth listening experience. The new antenna design also enhances connection stability. aptX Adaptive dynamically adjusts the speed of transmission, which doesn’t get affected even in complex environments. QHS doubles the transmission bandwidth, paving a wider road for wireless transmission. The crux of the issue lies in the limited bandwidth of Bluetooth, resulting in lossy audio compression and sound details missing.To solve this problem, we created Immersive DEEP-HD Audio using Qualcomm’s QHS high bandwidth technology, aptX Adaptive codec, and our own dual coupled antennas. We deeply analyzed the entire chain that affects sound quality, from source, digital signal processing, Bluetooth transmission to the structure of the sound unit.

Details of the sound are often lost, and connection may drop or be interrupted in places like airports and subways with significant wireless interference. Audio quality has been a constant challenge for Bluetooth earbuds for a long time.
