Disclaimer:

• To ensure optimal noise reduction, select the most suitable ear tip size.
• The feature is for reference only. Please refer to the actual product.
• Requires a compatible vivo/iQOO phone. For specific compatible models, please consult official customer service. Other Android devices require the "vivo Earphones" app.
• Call Noise Reduction filters background noise while clearly capturing human voices to improve call quality.
• Wind noise reduction performance depends on actual use.
• The data on microphone wind noise resistance is based on a wind speed of 3 mph. At a 1000 Hz frequency point, TWS 2 wind noise is approximately -80 dB, while vivo Buds wind noise is around -90 dB, an improvement of about 12%.
• The data on the battery life of music playback on a single charge is based on tests conducted in vivo laboratories at room temperature. With the earphones and charging case both charged to 100%, audio in MP3 format was played on a loop (50% volume, AAC standard, all sound effects turned off) until earphone power was reduced to 0%. Actual results may vary depending on the test environment, software version, and user habits.
• The data on the total battery life of music playback with the charging case is based on tests conducted in vivo laboratories at room temperature. With the earphones and charging case both charged to 100%, audio in MP3 format was played on a loop (50% volume, AAC standard, all sound effects turned off) until earphone power was reduced to 0%. The earphones were then charged to 100% using the charging case, and audio was played under the aforementioned conditions until the power was again reduced to 0%. Repeat testing was conducted until both the earphones and charging case were out of power. Actual results may vary depending on test environment, software version, and user habits.
• The data on call battery life from a single charge is based on tests conducted in vivo laboratories at room temperature. With the earphones and charging case both charged to 100%, a voice call was initiated with a phone (50% volume) until earphone power was reduced to 0%. Actual results may vary depending on the test environment, software version, and user habits.
• The data on the battery life on a 10-minute charging is based on tests conducted in vivo laboratories at room temperature. Using a vivo standard charger to charge the case, the earphones at 0% power were charged for 10 minutes with the charging case. Then, audio in MP3 format was played on a loop (50% volume, AAC standard, all sound effects turned off) until earphone power was reduced to 0%. Actual results may vary depending on the test environment, software version, and user habits.
• This technology is directly integrated into the earbuds and does not require adaptation with games. However, when playing a specific game, ensure that the "Ultra Game Mode" is enabled. There are two ways to enable the Ultra Game Mode: a. Automatic. Games downloaded from vivo/iQOO Game Center are whitelisted and will automatically enable Ultra Game Mode when launched; b. Manual. Games not downloaded from the Game Center need to be manually set to be added to the Ultra Game Mode. Use with optimized vivo/iQOO phones for best performance. The lowest latency may vary slightly depending on the model, audio codec, etc. Actual usage results may vary.
• The data on Bluetooth antenna signal strength is from vivo laboratory testing; signal coverage range test data is from vivo specified scenarios, with data compared to the TWS Air model.
• Switching between electronic devices requires vivo Earphones App.
• This model is not a professional waterproof earphone. Under normal use, it is splash-proof, water-resistant, and dustproof. Tested under controlled laboratory conditions, it meets the IP54 rating according to the GB/T 4208-2017 (domestic) / IEC 60529 (international) standards. The IP54 dust protection level means that it cannot completely prevent dust from entering, but the amount of dust that does enter will not affect the product's normal operation. The water protection level prevents water ingress from splashes in all directions. The IP54 dust and water resistance level only applies to the earphone body and does not cover the earphone case. The splash-proof, water-resistant, and dustproof functions are not permanently effective, and their protective performance may degrade due to everyday wear and tear.
• Requires compatible vivo/iQOO phones. Please consult our official customer service for specific compatible models.
• When vivo Buds earphones are removed from the charging case for the first time, they will automatically enter pairing mode. After the earphones are reset to factory settings, they will automatically enter pairing mode the first time they are powered on.
• The product pictures, internal structure and product effects are for demonstration purposes only. Please take actual products as standard.
• All data is based on our technical design parameters, laboratory test results and supplier test data. Actual performance may vary depending on software version, specific test environment and phone model. Please take actual products as standard.
• As some specifications, parameters, or parts of the product may vary due to supplier change or different production batches, vivo may update the descriptions on this page accordingly without giving any prior notice. Please read this page carefully before use.
