Overall, these comfortable earbuds offer an impressive noise cancellation system that does a decent job of reducing the low rumbles of bus or plane engines. The earbuds with precise voice pickup technology offer a comfortable hands-free calling experience. Combining the technology with microphones and a bone-conduction sensor, the earbuds pick up your voice clearly and accurately for hands-free calls. Additionally, the new bone-conduction sensor only picks up vibrations from voice -- it doesn't register ambient sound -- enabling even clearer speech when making calls. The earbuds also have a 'Speak-to-Chat' feature that lets users have short conversations without taking out the earbuds. As soon as a user speaks to someone, 'Speak-to-Chat' automatically pauses the music and lets in ambient sound so you can conduct a conversation. The earbuds also feature Adaptive Sound Control, a smart feature that senses where the user is and what he/she is doing - for example, travelling, walking or waiting - then adjusts ambient sound settings for the ideal listening experience. Users can opt to have Adaptive Sound Control learn to recognise places that they frequently visit, like the office, the gym, or a favourite cafe and tailor sound to suit the situation. On a full charge, the earbuds offer around 8 hours of power, and the handy charging case provides a further 16 hours to keep you going throughout the day. Also, a 5-minute quick charge can give users up to 60 minutes of playtime. Conclusion: If you are looking for great-sounding lightweight earbuds with impressive noise cancellation, voice-calling capabilities and good battery life, the premium offering by Sony has a strong chance of making it to your ears.
