Sennheiser Momentum 4

Pros

• Industry-leading battery life, cited at approximately 60 hours.
• Superior sound quality and musicality compared to many wireless competitors.
• Excellent value for money, especially when purchased on sale or open-box.
• Effective at filtering low-frequency engine noise during travel.
• Strong performance for electronic music due to its sub-bass capabilities.

Cons

• Latex-like earpads can trap heat, creating an 'igloo' effect for the ears.
• Lack of physical buttons; relies on touch controls that some find less reliable.
• Bulky form factor takes up significant space in travel bags.
• Headband foam and sliding mechanisms have reported durability or comfort issues over time.

Caveats

• While excellent for wireless, users note it still cannot compete with high-end wired headphones like the HD650 for pure musicality.
• Some users report an initial 'disappointment' period before acclimating to the sound signature and features.

Best for

Avoid if
