What reviewers said
Sennheiser HD 450BT
The Sennheiser HD 450BT are solid wireless over-ears that deliver reliable sound and effective noise cancellation at a budget-friendly price. They shine with their long battery life, quick USB-C charging, and foldable design, though comfort can be hit-or-miss for larger ears and the build feels somewhat plasticky. Overall, they're a competent, value-focused pick rather than a standout performer in the crowded mid-range market.
- Pro:Strong 30-hour battery life with fast USB-C charging
- Pro:Effective noise cancellation for the price
- Pro:Balanced, neutral sound signature
- Con:Ear cups run small, which may hurt comfort
- Con:Build quality feels a bit flimsy
