Soundcore (Anker)’s “Liberty 4” is a fully wireless earbud that effectively tames “loudness” while still letting you bring in outside sound when you need it. With Bluetooth 5.3 support as well as features like 3D audio and multi-point connectivity, it’s built with everyday convenience in mind.
Use ultra noise canceling (2.0) to reduce surrounding distractions on trains, in cafés, or during at-home work. Plus, with an ambient sound/bring-in-the-outside-sound feature, you can switch without taking the earbuds out—handy when someone talks to you or when you want to catch station announcements.
Bluetooth 5.3 helps you aim for a more stable connection—this is a key strength. On top of that, multi-point support makes it easier to use multiple devices, such as switching between your smartphone and PC. It’s a great match if you frequently switch between video watching and calls, or between work and commuting.
Designed to let you enjoy how sound spreads with 3D audio. Since it also supports Hi-Res audio, you can look for more detail and clarity when using compatible content. It also tends to satisfy people who prioritize “soundstage” and presence, regardless of genre.
In addition to playback on the earbuds alone, it supports up to 28 hours with the charging case included. Because you can use them longer to match your daily routine, they’re convenient if you don’t want to charge too often. Wireless charging is also supported, making it easy to keep a simple charging setup on your desk.





With an IPX4 water-resistance rating, you can use them with less worry about light sweat or water splashes. They also support health monitoring, so they don’t have to be only a tool for listening to audio—you can use them as a starting point for managing your day-to-day condition.
