What reviewers said
QCY H3 Pro
The QCY H3 Pro is a budget-friendly over-ear wireless headphone that packs a surprisingly rich feature set, including hybrid active noise cancellation, long-lasting battery life, and support for high-resolution audio codecs like LDAC. Its lightweight build and comfortable fit make it suitable for extended listening, while the included app adds customizable EQ options. The main compromises are found in the less premium build materials and a design that doesn't stand out.
- Pro:Excellent battery life of up to 55 hours
- Pro:Effective hybrid ANC for the price
- Pro:Supports high-quality codecs like LDAC and LDHC
- Con:Build quality feels less premium than features suggest
- Con:Design is not particularly stylish or distinctive
- Con:No water resistance rating
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
