Sennheiser HD 4.50 BTNC noise cancelling wireless headphones Features


The Sennheiser HD 4.50 BTNC Wireless headphone is pretty good-looking. It had a nice black and silver color along with the Sennheiser logo on each side of the headphones. The build quality and noise-canceling of the headphones is pretty good. They are light and easy to carry around. They use fairly narrow but thick cushioned and closed ear-cups. You will find a power button, a music playback control slider, and a volume rocker on the right ear cup if you hold down on both buttons at once. The volume rocker doubles as a way to activate or deactivate the noise cancellation circuit. With the headphones, you will get a soft carry case, an aux cable, micro-USB charging cable. The Sennheiser HD 4.50 BTNC headphones are well designed and look good.


These headphones not just look good, but they are comfortable too. They used a good amount of high-quality memory foam in earcups. They should use a little more foam under the headband for more comfort on the top of the head. However, we can wear headphones for hours at a time.

The sound quality of HD 4.59 BTNC is pretty good. The bass of Sennheiser headphones is deep, smooth, and powerful. The amount of bass on these headphones will be enjoyed by bass-lovers. But the sound profile isn’t necessarily natural. The headphones midrange is also pretty well-tuned. The low mids are warm and full-bodied, and the high mids are the little cut-off. They are not cut to the point of sounding bad. The high end sounds pretty good too. There are few things more about the sound of the headphones is the activating the noise cancellation does have a slight impact on the sound, and when deactivated. There is a small boost in high frequencies and little less bass oomph. Overall the headphones are sounded great with and without noise cancellation.


The wireless headphones feature a standard Bluetooth 4.0 connection. It has a 30ft or 10 m range. The result will be depending on things like obstacles.

The NoiseGuard is effective. The music does lose the little of its luster when the headphones are in NoiseGuard mode. It also might fall just shy of the tech found on Bose and Sony headphones, but it delivered in a fair better value package, and the volume goes very high without any distortion.
