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
“Impressive features, style, and noise cancellation add up to a worthy option for budget shoppers.”
Sleek, understated style, Excellent battery life, Good build quality, Solid noise cancellation, Smooth, clean bass response
Inconsistent sound signature, No auto-pause or ambient sound mode, App/EQ not useful
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...
Sound quality, Bluetooth 5.0, aptX Low Latency and AAC, Portable design, USB-C
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.
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.
Even though it isn’t perfect, the Sennheiser HD 450BT does still offer very good value to performance proposition for the price tag it sports. You definitely get slicker wireless headphones with noise cancellation, but those cost a lot more—the Sony WH-1000XM3 (around Rs 29,990) and the Bose Noise...
The Sennheiser HD450BT wireless headphones come packed with plenty of high-end features, like noise cancellation....
If all you’re looking for is a well-balanced, comfy, inoffensive portable headphone, the HD 4.50BTNC continues to be pick from Sennheiser. However, I find the HD 450BT to be a more enjoyable listen for its unique and relaxed sound signature.
Do I recommend the Sennheiser HD450BT? If you don’t mind a little warmth, and you have a spare $200, I’d certainly recommend checking them out.
I was impressed by the overall sound quality and noise cancellation capabilities of these headphones. They are also very comfortable to wear for extended periods of time. My only minor negative comment is that I didn't find the controls to be intuitively obvious but I have gotten used to them with...
Sound quaity and noise cancellation are excellent
Controls are not explained well in the accompanying set up and operating instructions. But they are easy to work with once you figure them out.
They are great!! Thank god for Zo. He really knows what he is talking about.
I believe for the price an overall great value. Minor things would be ear coverings appear to be a little small and when talking on phone via Bluetooth mic seems to pickup everything But people can hear my voice clearly.
Great sound and no outside noise
Ear pads could be a little bigger.
One charge lasts me about 40 minutes. Also, no mic mute button. I am a big fan of Sennheiser products, but not this particular one.
Relatively light and comfortable, good sound quality
Poor battery time. No mic mute.
Overall these are a good pair of headphones for the price. High quality and modern codecs top the list. The audio is really good for this price point, which is why I give it four stars. I have a big head and wear glasses, and they hurt my head by my glasses after about an hour.
Not the best but a good value at this price point. Comfortable and sounds VERY good to my ears.
Comfortable, good feature set and good sounding.
Have not used them enough to find any.
The sound is great. The pairing is painless. However the headphone "cans" are too small. I could not wear these for more than a few minutes. I passed them on to my son who is also very happy with the ease of pairing and the sound quality. A very good product but make sure you test their fit!
Bought as a chrissy gift for the Mrs, she was chuffed. Packed with features, a nice battery, it's comfortable over hear ears too and she can chuck em on and cancel out most of what I'm saying. The noise cancelling isn't 100% but it does the job and the sound out of them is really nice and clear.
For their price (I got on sale), these are good headphones. I have a smaller sized head so the headphones easily cover my ears completely so is great for passive noise cancelling. Sound quality is good and noise cancelling is average.
Very happy with the quality would recommend for anyone with ears
