What reviewers said
FiiO FG3
The FiiO FG3 is a budget-friendly wired over-ear headphone designed for audiophiles on a tight budget, featuring a hybrid dual-driver setup with a large 50mm dynamic driver for detailed sound. It offers a detachable cable, a wide frequency range, and app-based EQ tuning, but lacks wireless features and noise isolation, making it a niche pick for stationary listening. Its open-back design contributes to a spacious soundstage but also means significant sound leakage and no passive isolation from ambient noise.
- Pro:Excellent value for a hybrid driver setup
- Pro:Detachable cable and USB-C support for versatility
- Pro:Customizable sound via app-supported EQ
- Con:No active noise cancellation or isolation
- Con:Open-back design leaks sound and lets in noise
- Con:Requires a wired connection and external amp for best performance
Sennheiser HD 400
These over-ear Sennheiser headphones are built around a neutral, open-back design aimed at studio work, delivering a wide soundstage and detailed, transparent audio for critical listening. They are lightweight and comfortable for long sessions, with a high-impedance driver setup that helps maintain low distortion, though they lack isolation and come without a carry case. Wired connectivity via USB-C and detachable cables adds versatility, but the open-back nature means sound leaks both ways.
- Pro:Accurate, transparent sound with wide soundstage
- Pro:Lightweight and comfortable for extended wear
- Pro:Detachable cables and USB-C connectivity
- Con:No included carry case or spare ear pads
- Con:Open-back design leaks sound and offers no isolation
- Con:High impedance may require a dedicated amplifier for best results
