Soundcore by Anker Liberty 4 NC
The Soundcore Liberty 4 NC are wireless in-ear headphones specifically designed to offer extreme noise isolation. Their standout feature is the Adaptive ANC 2.0 system, which promises to reduce up to 98.5% of external noise by calculating ambient noise and the internal structure of your ear canal in real time. They boast Hi-Res Audio Wireless certification thanks to Sony's LDAC codec, which transmits up to three times more data than standard Bluetooth for high-fidelity sound. They impress with one of the longest battery lives on the market: up to 10 hours of playback on a single charge and a total of 50 hours when combined with the charging case. Furthermore, they are IPX4 certified and feature a robust mobile app for complete audio customization and touch controls.
Pros
Brutal and highly effective Active Noise Cancellation (ANC), on par with models twice the price.
High-resolution audio support via the LDAC codec.
Colossal battery life of up to 50 hours with the charging case.
Soundcore mobile app with HearID equalization that adapts the sound to your hearing ability.
Cons
The sound profile comes from the factory heavily saturated in bass and treble (V-shaped profile), requiring adjustment in the app to balance it.
The size of the earbuds and their case is slightly more robust than those of the competition.
Connection stability may experience slight micro-dropouts if LDAC mode is activated in environments with high wireless interference.

The high-end destroyer: absolute silence and endless battery at an unbeatable price.
If you're looking to completely isolate yourself from the outside world on a plane, train, or in the office without spending a fortune, the Liberty 4 NC headphones are the ultimate solution. Their active noise cancellation is simply spectacular; it attenuates bass hum with astonishing effectiveness, directly rivaling Sony or Bose. Musically, thanks to LDAC support, they reveal a wealth of detail, although the initial equalization is quite aggressive at the extremes (thumping bass and very pronounced treble). Fortunately, their excellent mobile app allows you to tame this profile and tailor it to your liking. Add to that a seemingly endless 50-hour battery life and a highly addictive magnetic charging case, and you have one of the most well-rounded and highly recommended products in this comparison.
