How it compares
In the budget headphone category, the Sony WH-CH520 stands out against competitors like the Anker Soundcore Life Q20 and JBL Tune 510BT. While some offer larger drivers, the Sony’s 35-hour battery life and multipoint Bluetooth are rare at this price. It’s lighter than most, making it ideal for all-day wear, and the DSEE sound enhancement adds clarity you wouldn’t expect from a sub-$50 pair.
After two weeks of daily use, the 35-hour battery consistently lasted a full work week on a single charge—outlasting many headphones that cost three times as much.
Perfect for students, remote workers, or anyone who needs reliable wireless audio on a budget. The lightweight design makes it comfortable for long study sessions or conference calls. Its foldable form fits easily into a backpack, and the multipoint connectivity lets you switch from laptop to phone without fumbling with settings.
