Sennheiser 450bt Headphones Review: Good But Could Have Been Better

Sennheiser 450bt Headphones deliver good sound quality, but aren’t comfortable enough as they lack spacious earcups for a wide audience. These noise-cancelling headphones do a good job of reducing ambient noise, but not as well as their big brother, the Sennheiser PXC 550-II.

Does The Job

Good ANC headphones can usually cost a lot, but the Sennheiser 450bt does the job for just $216. Battery life is good enough for many round trips, but with ANC it’s no easy task. Still, the 450bt is an affordable noise-cancelling headset. Let’s see if the price can tolerate its shortcomings. 

PRO: Sound Quality & Battery Life

  • The Sennheiser 450bt Headphones offer great sound quality with a well-balanced bass production and a clear sound reproduction.
  • If you are a fan of road trips and traveling, the Sennheiser 450bt Headphones will be an excellent choice for you. The Sennheiser 450bt Headphones offer up to 30 hours of playback on a single charge.

PRO: Portable Design & Reliable Connection

  • With Bluetooth 5, the Sennheiser 450bt Headphones can seamlessly pair for a reliable wireless connection with your devices.
  • Portable design makes it easier to carry the headphones around.

CON: No Fast Charging & Poor Microphone

  • When the battery runs out, you can easily charge it using the included USB-C cable. But there is no fast charging, so it should take 2 hours to fully charge the headphones. 
  • The build-in mic performance is sufficient for voice calls, but it may not meet the expectations of users who demand high sound quality for voice recording, online games, etc.

CON: Limited Controls & Uncomfortable Fit

  • Limited controls with only basic functions like play/pause and volume control available.
  • The oval earcups are ergonomically shaped, but average to above-average ears unfortunately seem to not sit comfortably. Some users report that the Sennheiser 450bt headphones are more on-ear than over-ear. 

Where to buy the Sennheiser 450bt Headphones in Australia

Overall, the Sennheiser HD 450BT are very impressive, especially in terms of sound. Its balanced profile should satisfy both audiophiles and bass hunters.

Battery life and connectivity are both great, and the ANC works reasonably well, but you’ll find that these headphones don’t completely block out all external noise. 

If you are a gamer or a content creator and value comfort and mic quality you might want to look for alternatives but if you need a good pair for your travels the Sennheiser 450bt Headphones should be a solid choice with the exception of no fast charging.
