Our Verdict
The QZ900 do well as everyday casual headphones. They lack a little isolation for loud environments but perform decently well under other test cases. Sadly their sound quality is not the best.
- Lightweight and comfortable.
- Great seal, leaks very little sound.
- Poor in-line control options.
- All plastic build, feels cheap.
- Bass-heavy audio reproduction.
Subpar for critical listening. These headphones have a closed sound and a skewed, bass-heavy audio reproduction. This makes them sound too dark for critical listening.
Not ideal for commuting. They have below-average noise isolation and won't be able to cancel the loud ambient noise of a busy commute.
Below-average for sports use. They're lightweight, comfortable and stable. However, they're a bit bulky and don't have a decent control scheme.
Below-average for office use. The weak noise isolation does not cancel the ambient noise of busy office, but they don leak much.
Mediocre at best for home theater use. They have negligible latency since they're wired headphones. However, their poorly balanced sound and limited range won't be ideal for watching movies.
