Sennheiser HD 450BT review

By Olivia Tambini. Review Source




Sennheiser is well-known for its great-sounding noise-cancelling headphones, and its latest, the Sennheiser HD 450BT, offer a cheaper alternative to previous models like the Momentum 3 Wireless and class-leaders like the Sony WH-1000XM3.


With a minimal design and built-in noise cancellation, these fully-foldable wireless headphones are aimed squarely at the commuting crowd. But how do they stack up against their pricier competitors?


We put the Sennheiser HD 450BT to the test, and we think the company is onto a winner with these sleek over-ear headphones.




Design


These minimalist over-ear headphones come in black and white color variants; we tried the white model, which sport chic silver-gray ear cushions and detailing on the headband.


They look quite stylish, if not as eye-catching as the recently released Sennheiser Momentum 3 Wireless headphones; for some, the subdued design may be a little underwhelming, but if you prefer an understated design, these cans will probably be right up your street.


Fully-foldable, the Sennheiser HD 450BT are geared towards listening on the go, and can be easily stowed away in your bag when not in use. Thanks to that foldable design, they take up a minimal amount of room in your bag, making them ideal for travel.




Compared to the Momentum 3 Wireless headphones, the build of the new cans feels less premium and less sturdy: the plastic construction could even be described as feeling flimsy.

The build of the new cans isn't as sturdy or premium as the Momentum 3 Wireless headphones, and the plastic construction can feel a bit flimsy at times.

While that lower-grade build is reflected by the lower price, it wouldn't be unreasonable to expect a more luxurious finish for the money.

One benefit of this plasticky design is that the HD 450BTs feel very light, and are comfortable to wear during long listening sessions. The earcups are generously padded, and they don’t lead to the clamping sensation that’s common with on-ear and over-ear headphones.

On the bottom of the right earcup you'll find a USB-C charging port, a 3.5mm jack, buttons to control your music playback and voice calls, and a dedicated button to summon your voice assistant of choice, whether that's Siri or Google Assistant.




Battery life and connectivity


With 30 hours of battery life (that’s with active noise cancellation turned on), the Sennheiser HD 450BTs can stand up against the Sony WH-1000XM3, and beat the Bose Noise-Cancelling Headphones 700 by a significant 10-hour margin. It’s also far superior to the 17 hours offered by the more expensive Sennheiser Momentum 3 Wireless.


Pairing these wireless headphones with our devices was a breeze, thanks to Bluetooth 5.0 support. Gamers will be pleased to know that, as well as codecs like aptX, AAC, and SBC, these cans support aptX Low Latency, so you shouldn’t experience any annoying lag between what you’re seeing on your screen and hearing through the audio. When watching video on our smartphone, we didn’t experience any latency issues either.
