Anker Soundcore Liberty 4 Pro Review: Dramatically Better Sound, Superior Comfort, and Premium Features at This Price?

Hello, I’m Itsuki (@saigalog).

Do you think that you can’t get “great sound” unless you buy expensive earphones?

To be honest, I also believed that only high-end wireless earphones could deliver truly great sound quality and a comfortable user experience.

However, Anker’s “Soundcore Liberty 4 Pro” pleasantly proved that assumption wrong.

Despite being priced under 20,000 yen, it supports LDAC for high-resolution audio playback, spatial audio for enjoying immersive sound, and also includes essential everyday features like noise canceling and multipoint connection.

It’s an “all-in-one” spec lineup that almost makes you want to ask, “Can it really do all this at this price?”

This time, I’ll take a detailed look at my real impressions after actually using it, including sound quality, comfort, and usability.
