Sony LinkBuds vs Soundcore Liberty 4 NC
The Verdict
Sony LinkBuds and Soundcore Liberty 4 NC serve different listening philosophies at vastly different price points. The LinkBuds use an innovative open ring driver design that prioritizes ambient awareness, making them ideal for people who need to stay connected to their surroundings during commutes or outdoor activities. They weigh just 4.1g per bud and deliver 5.5 hours of playback, with a total of 17.5 hours including the case. Soundcore's Liberty 4 NC takes the opposite approach with active noise cancellation claiming 98.5% reduction, plus LDAC codec support for hi-res audio quality. At 7 hours with ANC enabled (10 hours with it off), they offer significantly longer battery life, and the included wireless charging case adds convenience that the Sony lacks. The Liberty 4 NC costs $100 less while delivering more traditional premium features. For someone prioritizing noise isolation, hi-res audio, and value, the Soundcore Liberty 4 NC is the clear winner. However, if you specifically want open-design earbuds for situational awareness and don't need ANC, the LinkBuds justify their premium through unique design philosophy. Most buyers seeking standard in-ear performance will find better value in the Liberty 4 NC.
