Sennheiser HD 450BT : Design and use
Sennheiser HD 450 BT come with a simple look and sleek design. Ear cup rotation is minimal, which doesn’t affect comfort but does limit transport options. Moreover, over ear cups are ergonomically shaped. But there is not much room to fit comfortably in the ear above average.
However, Some users have even reported that these headphones fit more like on-ears than over-ears. While this is a bit troublesome. It makes the headset more portable than the expensive Hifiman Edition XS headset. Additionally, it come with an improve texture or synthetic leather. Thus, you can always use your favourite earbuds.
Headphones such as the JBL One Tour give you the option to flatten and head up the headphones. While with HD 450BT your only option is to fold the ear cup towards the headband. This works well with the provided case. But if you are a student and have a habit of putting your headphones in the bag then you should avoid these headphones. And it may be more comfortable to use JBL One Tour or any other instead.
When I first put on the headset, I found the fit borderline painful because of the clamping force. And how the hotspot forms on the top of my head. After a week of continuous use, the headset became loose. Afterward, i have been able to wear it for hours at a time. Although this can be severely shortened when wearing glasses.
How to use the onboard controls
Here’s a quick list of controls so you don’t fumble around as much as I did.
- Tap and hold the power button for two seconds to turn the headset on/off.
- Press the power button once to toggle noise cancelling on/off.
- Press the voice assistant button (closest to the headphone yoke) to talk to your virtual assistant.
- Slide the switch back (located just below the voice assistant button) to skip back a track.
- Slide the switch forward to skip to the next track.
- Press the switch like a button to pause or resume playback.
- Press the volume rocker up or down to adjust media output.
For calls you have two options:
- Depress the switch button once to answer or end a call.
- Press and hold the switch button for two seconds to place a call on hold.

Sennheiser HD 450BT : Audio quality
The only good thing about Sennheiser is its sound quality. Which is awesome than any other product like Bowers & Wilkins PX7. The bass is powerful but it won’t rumble your cranium like a beat. Its frequency range is 18 Hz to 22,000 Hz (-10 dB). Sennheiser keeps to its roots with a few minor deviations to make for a more engaging but still accurate sound.
The Sennheiser HD 450BT is a mid-tier Active Noise Cancelling headset. That renders low-frequency sounds up to half as loud with ANC enabled when feature is disabled. While this change is worth listening to, you can get a much better performance with other headsets that cost a bit more like the Sennheiser HD 400 Pro. When using the headset from the outside, the wind and noise from the passing car were less pronounced, but both sounds were clearly audible.
Passive isolation performs heavy lifting until blocking mid-range and trouble frequencies. This is because it is very difficult for ANC to block speech and unexpected sounds like your run-of-the-mill clangs and pangs. Which often come above 1kHz. To get the most out of noise cancellation technology. You should make sure the headphones are snug and leave no gaps between your head and ear pads.
The Sennheiser Smart Control app means you can easily customize the sound to your personal liking – thanks to an intuitive equalizer. In addition to battery status and firmware updates, the app has a podcast mode that optimizes audio settings for podcasts, audio books, and other spoken content.
This free dedicated app for iOS and Android provides an effortless way to control, personalize, update and configure your Sennheiser headphone, headset or soundbar.

Sennheiser HD 450BT : Connectivity
Talking about the connectivity, the most important features of this headphones is that it come with a Bluetooth Multipoint support. Because of this, Sennheiser HD 450BT allows headphones and earbuds to connect and maintain multiple devices simultaneously. Multipoint permit users to faultless switch between devices such as computers and phones.
Additionally, when my laptop and smartphone are connected to the HD 450BT, text and email notifications are not sent to my headset from a secondary source device. The only event that notifies the headset is an incoming call.
Sennheiser HD 450BT uses Bluetooth 5.0 and supports enough of Bluetooth codecs: SBC, AAC, aptX and aptX low latency. Then whether you are an iPhone or Android user, you will be able to stream audio continuously on headphones. If you subscribe to a streaming service like Tidal or Amazon Music HD and want to take advantage of FLAC files. You can always use the included 2.5mm to 3.5mm cable.
Sennheiser HD 450BT : Battery
We enabled Bluetooth and noise cancellation while subjecting the headset to a constant 75dB (SPL) output, and the battery lasted 27 hours, 2 minutes. This is a little less than the listed 30-hour battery life but it is still exceptional and more than necessary for a normal listener. Once the battery is exhausted, it’s easy to top up with the included USB-C cable. Fast charging is absent, so you’ll need to set aside two hours to fully charge the headphones.
The Sennheiser HD 450BT is a very good pair of headphones for the price, good sound cancellation and excellent sound quality. Which is quite rare at this price stage. Like any product, this headset is not without its drawbacks and can be difficult to justify when the price of Sennheiser HD 400 Pro is a bit high. Sennheiser HD 400 Pro is more comfortable, has a better mic and offers a more efficient ANC that can be adjusted in the application. Even if someone’s ear in your life is less than average, the Sennheiser HD 450BT can be a perfect gift, and at $ 129 it’s not even the most expensive gift.
What should you get instead of the Sennheiser HD 450BT?
The Sony WH-1000XM4 costs more than twice as much as the Sennheiser HD 450BT but is worth considering if you’re in it for long distances. Sony’s headphones use AI technology and are the best sound-cancelling headphones available. Battery life, while less than the Sennheiser HD 450BT, is very good and fast charging is supported. There may be fewer Bluetooth codecs supported by Sony’s headsets, but they have LDAC that, when compatible, streams at a higher rate than aptX.
Listeners who do not need ANC want to consider Austrian Audio Hi-X55. Further, Audio-Technica leaves out first-generation aptX support for high-quality LDAC codecs. One of the best things about it, however, is its insane battery life.
I have a small head. Will the headband fit me or will it flop around?
The Sennheiser HD 450 BT is definitely a good headset for people with small heads and ears. But it cannot be guarantee that it will fit your head. We generally recommend something from Puro Sound Labs, such as the Puro Sound Labs BT2200 headset, for listeners with small heads who want active sound-cancelling headphones. The company designs headphones for kids, but the cans don’t have the gritty design you get on other children’s headphones so they’re perfectly suited for adults as well.
Should I get these or the Sony MDR-XB950B1?
Noise cancelling performance is very similar between the Sennheiser HD 450BT and Sony MDR-XB950B1, but the Sennheiser headphones do a slightly better job of cancelling out low-frequency noise. The default frequency response varies between the two headsets: Sony de-emphasizes bass, while Sennheiser amplifies low-bass and upper-midrange notes. Both mobile apps allow you to EQ the sound to your liking.
Both headsets have completely plastic exteriors, though the Sennheiser HD 450BT seems a tad more durable. Ultimately, the headsets are very similar. If you want mic quality get the Sony MDR-XB950B1 and if you value ANC performance, get the Sennheiser HD 450BT. Alternatively, you may also want to consider the Sony MDR-XB950B1, which feature modern comforts like USB-C charging and a sleeker design.
Why do I hear a hiss when music isn’t playing?
Generally, with some Bluetooth headphones, you can hear the electrical interference from the integrated amplifier. This should not be audible during music playback. While our purchased unit did not have this latent “hissing” sound, users have reported it. To fix the problem, reset your headphones. If all else fails, contact Sennheiser Support.
