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.

A dedicated NC processor assures that you will never lose quality in your music reproduction.
