Sennheiser HD 450BT vs Sony WH-1000XM3: Detailed Comparison

Just recently, both the Sennheiser HD 450BT and the Sony WH-1000XM3 were just released in the market. The features of these headphones are also relatively close to each other, and so it is understandable if some people are confused when trying to pick out which one between these two headphones they should opt for. Comparing them by their specifications alone might make the choice seem easier since both of them have very similar features, but that is not always the case with audio equipment.

When it comes to headphones especially when you’re into audio, you need to be very careful with what you pick out. Just because a headphone claims to be the best doesn’t necessarily mean it is; we should always go for quality over quantity. It may be true that no one can ever get tired of music, but not all headphones can give the same kind of experience while listening to music.

The frequency of the audio signal is what decides the depth and quality of the sound. That’s why it is important to consider this feature when looking for a pair of headphones. In case you are not familiar with these technical terms, it means that the range of human hearing only goes from 20Hz to 20kHz so as long as the audio codecs support this range, then those are good enough for professional usage.

Touch Control

Sennheiser HD 450BT: Yes
Sony WH1000XM3: No

The Sennheiser HD 450BT can be controlled by touch on their ear cup controls. There are quite a few other headphones out there that have the same feature as well, but still, not all headphones have it. The touch control feature in audio equipment proves to be very handy and is very easy to use. However, everyone may not like the touch control features as they may accidentally trigger them. Sadly, the touch sensor control panel of the Sennheiser HD 450BT cannot be turned off or disabled.

Sennheiser HD 450BT: Yes
Sony WH1000XM3: Yes
Winner: Sony WH1000XM3

Since both the Sennheiser HD 450BT and the Sony WH1000XM3 both have active noise cancellation features, you might be thinking about it hard to decide which one is better.

However, Sony WH1000XM3 is far better than the Sennheiser HD 450BT, as it has far better noise cancellation capabilities. Sony’s WH-1000XM3 headphones are equipped with the company’s most highly advanced noise-canceling technology. In addition to the headphones’ close-fitting ear cushions, Sony has incorporated its HD Noise Canceling Processor QN1 into the headphones. A dedicated NC processor assures that you will never lose quality in your music reproduction.

Sony WH1000XM3 claims it features multiple microphones
The design of this kind of headphones doesn’t allow them to put the microphone in the right place. No matter how sensitive microphones are used, they often catch ambient noises more than the speaker. If you are particularly looking for a microphone option, these may not be the right candidates.

NFC

Sennheiser HD 450BT: No
Sony WH1000XM3: Yes
Winner: Sony WH1000XM3

Sony WH1000XM3: Yes
Winner: Sony WH1000XM3

Sony WH1000XM3: 30 Hours
Winner: Tie

Winner: Sennheiser HD 450BT

Both these headphones are lightning fast to charge when you’re electronics are being plugged in by a source such as your laptop or an external charger. Sennheiser HD 450BT is faster than the Sony WH1000XM3 because of its shorter charging time.

You cannot listen to Sony WH1000XM3 while charging, however, you may plug in the supplied aux cable to continue listening while charging. But, note that noise cancellation doesn’t work when headphones are turned off.

For both headphones, the battery is charged via USB-C, and fast charging is available as well. The Sony WH1000XM3 can be used for up to 5 hours after 10 minutes of charging.

Comfort is very subjective as it depends on your ear shape. Both these headphones are very comfortable to use. You must know that comfort is not the main focus of either of these headphone models. They were designed for their noise-canceling capabilities rather than comfort.

However, Urethane foamed ear pads in Sony WH1000XM3 cushion your ears and relieve pressure. They stay in place better so you don’t lose them. Ergonomically constructed ear spaces provide a wider and deeper fit.

Foldable Headphones

Sennheiser HD 450BT: Yes
Sony WH1000XM3: Yes
Winner: Sony WH1000XM3

Both Sennheiser HD 450BT and Sony WH1000XM3 are foldable headphones, but Sony WH1000XM3 is the winner when comparing them since they can fold very flat and take the smallest space in your bag when you travel.

Innovation

Real-time upscaling of compressed digital audio files is achieved using DSEE ExtremeTM (Digital Sound Enhancement Engine) in the WH1000XM3. It recovers the high-range sound lost in compression for a richer, more comprehensive listening experience by dynamically identifying instruments, musical genres, and specific song components such as voices or interludes.

Sony WH1000XM3’s Adaptive Sound Control changes ambient sound settings based on your activities as you travel, stroll, or wait. It is possible to adjust the volume of your headphones without removing them, and Quick Attention gives you the freedom to converse without unplugging them.
