Our Verdict
The MM 550-X are compact over-ear, noise canceling headphones ideally for traveling and commuting. Unfortunately, they're lacking a strong isolation performance and their sound quality may be a deal breaker for some.
- Lightweight, compact design.
- Don't leak much sound.
- Poor noise cancelling.
- Bass lacking.
Sub-par for critical listening. They have a sharp and poorly balanced sound with a small Soundstage. They lack an exciting bass and their treble range is too harsh for most.
Below-average for commuting. They're compact and easy to carry around but don't block a lot of noise.
Average for sports. They're lightweight compact and wireless. However, they're a little unstable for high-intensity exercises.
Decent for office use. They will only reduce a little bit of office chatter but on the upside, they don't leak much.
Average for home theater use. Their sound quality lacks a little excitement, and if you don't have an aptX-ready source, then the latency delay will be noticeable.
