The Sennheiser MM 450-X Wireless are compact on-ear headphones that sound surprisingly great. They reproduce vocals and instruments well and provide enough isolation for moderately loud environments. Unfortunately, the very small on-ear cups are uncomfortable and the headband doesn't feel sturdy or durable.

Our Verdict

0.0
Mixed Usage 

The MM 450-X are compact noise cancelling headphones ideally for traveling and commuting. Sadly, lacking a strong isolation performance, they're best used as everyday casual headphones.

Pros
  • Lightweight, compact design.
  • Great audio reproduction.
Cons
  • Uncomfortably small ear cups.
  • Weak, flimsy build.

Critical Listening 

Average-at-best for critical listening. They have a decent sound but a poor soundstage. They won't reproduce high-res audio with the clarity and detail of an open back design.

0.0
Commute/Travel 

Mediocre for commuting. They're compact and easy to carry around but don't block much noise.

0.0
Sports/Fitness 

Not ideal for sports, They're lightweight compact and wireless. However, they're a little unstable for high-intensity exercises.

0.0
Office 

Decent for office use. They'll only reduce a little bit of office chatter but on the upside, they don't leak much.

0.0
Home Theater 

Average for home theater use. They have a better sound than the MM 550-X, and a relatively low latency performance with aptX enabled. however, they'll still have a noticeable delay, and they're not the most comfortable headphones to wear for long movies.
