Our Verdict
The Sony MDR-ZX770BN are mediocre everyday headphones. Their lightweight comfortable and have a wireless design. However, they poorly isolate and plasticky build quality. This makes them not versatile enough for some use cases and environments.
- Lightweight, comfortable design.
- Efficient controls and ergonomic button layout.
- Great audio reproduction.
- Flimsy joints and build quality.
- Poor noise isolation.
- Bass and treble delivery varies significantly across users. Sensitive to glasses.
Decent for neutral listening. They're comfortable for long listening sessions and have a decently well-balanced sound but they won't be the ideal choice for more neutral listeners.
Decent for commuting. They're comfortable and have a good control scheme, but their noise isolation is a little weak for loud environments.
Average for sports. The Sony ZX770BN have a lightweight and comfortable wireless design, and an efficient control scheme. However, they are too unstable and bulky for strenuous exercise.
Decent for office. They leak a lot and have poor ambient noise isolation. You will be able to hear the chatter of a busy office.
