Soundcore Liberty 4 Pro by Anker - Unrivalled Noise Cancelling with Studio-Grade Sound
The Soundcore Liberty 4 Pro redefines what wireless noise cancellation means for everyday listeners. Equipped with 7 sensors including 6 acoustic microphones and a barometric pressure sensor, the earbuds capture ambient noise from every direction simultaneously. Adaptive ANC recalibrates every 0.3 seconds to match your environment in real time, delivering noise cancellation that is 3 times stronger than conventional models whether you are on a plane, a busy train, or in a noisy open office.
The audio experience is built around the enhanced ACAA acoustic technology with a 10.5mm bass driver wrapped in a titanium diaphragm and a digital crossover that ensures each frequency is delivered with precision and clarity. Every genre of music comes through with studio-level depth and detail that sets the Liberty 4 Pro apart from anything else in its class, while the touch strip on the case lets you adjust ANC levels with a single swipe without interrupting your listening session.
With 10 hours of playback per charge and a total of 40 hours with the case, these earbuds are built to last a full week of daily use. The 5C fast-charging technology, twice as fast as previous models, gives you 4 hours of playback from just 5 minutes of charging. Nine AI-powered microphones combined with a wind noise reduction algorithm ensure that every call you make is crystal clear regardless of weather conditions or surrounding noise.
