Soundcore Q20i
Score: 82/100Rankings
The Soundcore Q20i delivers hybrid active noise cancellation, an impressive 40-hour battery life, and app-based EQ customization at a budget price. Its relatively heavy weight and reliance on wired Hi-Res audio limit some premium use cases. Perfect for budget-conscious commuters who need long battery life and effective ANC.
The Sony MDR-7506 is a professional closed-back studio headphone known for its accurate sound reproduction and excellent isolation. Lacking wireless connectivity and on-headset volume controls makes it less versatile for modern mobile use. Best suited for audio engineers and broadcasters who need reliable wired performance.

Professional reviewers highlight the Q20i's strong hybrid ANC, long battery life, and the inclusion of Hi-Res audio support via the AUX cable as standout features for a budget model. They also commend the app's EQ customization and multipoint Bluetooth, while noting that comfort assessments rely on user feedback and spec inconsistencies may cause buyer uncertainty.
Everyday users consistently praise the headphones for their marathon battery life, comfortable ear pads, and punchy bass, while common frustrations revolve around the single call mic, the relatively heavy weight, limited Bluetooth range, and the need to use a wired connection for true Hi-Res audio.
