Sennheiser's HD 450BT headphones deliver excellent Bluetooth audio and solid noise cancellation for a bargain price.
Strong noise cancellation for the price, Excellent audio performance, Can be used in passive mode with cable, or wired mode with ANC enabled, User-adjustable EQ
Noise cancellation is solid, but not class-leading
Sennheiser is one of the most recognizable names in audio. Even though the company's wireless products sometimes lack features found in competitors from Samsung or Sony, they usually offer best-in-class audio.
SoundThe HD 450BT sounds great, though the bass is boosted by default., SoftwareThe EQ can be adjusted with an app, and aptX/aptX Low Latency support is a nice bonus., PriceThese can usually be found for $150 or less, which is a competitive price.
DesignThe button layout is a bit confusing, and the restrictive band might be uncomfortable for some.
Although Sennheiser nailed the sound quality, it failed to create a comfortable headset with spacious ear cups for a wide array of listeners. These noise cancelling headphones do an okay job of reducing background noise, but don’t perform nearly as well as their big brother, the Sennheiser PXC...

Microphone quality, Uncomfortable fit, Poor button layout, No fast charging
The Sennheiser HD 450BT are satisfactory for commute and travel. These bulky headphones have an okay ANC cancelling feature that can help cut a small bit of bass-range noise like bus or train engines, but it likely won't be enough for an ambient noise-free experience.
Over 24 hours of continuous battery life., Okay ANC feature.
Some users may find these headphones uncomfortable.
“Impressive features, style, and noise cancellation add up to a worthy option for budget shoppers.”
When it comes to quality audio, Sennheiser is one of those names that just stands out in a crowd. It makes excellent headphones, soundbars, earbuds, and even pro audio that people have trusted for years. And, the company’s newest set of cans, the HD 450BT, is no exception.
Good sound quality, Very comfortable for on-ears, Excellent battery life
Wonky controls, Not the best noise canceling, No auto-power options
Sennheiser's most affordable NC headphones Sennheiser HD 450BT is a safe purchase.
Nice feeling of quality. Good sound and ok noise reduction. AAC and aptX support. USB-C charging.
Cannot be folded. A little uncomfortable. Too many confusing buttons.
These days £159 (inc. VAT, or $199.95) is not a huge price to pay for a good set of over-the-ear headphones, and that's what you'll shell out for the new Sennheiser HD 450BT . Indeed, when faced with a choice between this headset and the £250 Sennheiser MB 660 UC which I reviewed last year, you may...
Sennheiser’s HD 450BT wireless over-ears support high-quality audio codecs with AAC as well as aptX, they also offer low latency for watching movies and playing computer games thanks to aptX LL.
The Sennheiser HD450BT wireless headphones come packed with plenty of high-end features, like noise cancellation....
Purchased to be used with my LG TV so that I would not be distracting my wife. I was impressed with the final results. Sound quality was very good. Really like the ANR feature. The setup documentation is lacking to say the least. I guess tech writers are a thing of the past.
They are great!! Thank god for Zo. He really knows what he is talking about.
I just purchased these. They sound great but the tiny pamphlet that is the “set up manual” makes absolutely zero sense. Horrible pictures with no context.
Real good battery and sound love them
they are great headphones for their price much better than I thought the noise cancelling works great and the battery life lasts ages. Had a little bit of trouble connecting without the help of the smart control app but overall a great purchase.
I had been looking at reviews for these headphones and heard that they're more than okay, but just not worth the price tag. So I waited for a sale. I soon found a very good sale here at PB online. I've had them for a couple weeks now and sure, These are fine headphones. Premium exterior looks.
Pros: light weight, good sound, battery life.Cons: suit smaller ears
The noise cancelling feature is really good and the sound quality is not too bad for the price but could be a little better Love the white and nice build quality
Present for my wife for her studies. She absolutely loves them. They look great, are super comfortable, sound amazing (easily as good as my Bose QC35ii) and the noise cancelling works well - I can be (and am) noisy around the house without disturbing her concentration.
