The Sennheiser HD 4.50 BTNC are the most high-tech, wireless noise-cancelling headphones. They are packed with state-of-the-art features thanks to the brilliant engineering. The headphones are built to be portable which makes traveling more pleasurable. On the other hand, they are comfortable even after extended listening sessions. They are versatile, vibrant and come with a foldable-headband design. The headphones give control at your fingertips; you can change a track, make a call or adjust the volume through the intuitive earcup-mounted controls. In this article, we have summarized for you an all-inclusive review to aid in your purchasing decision.
The headphones are fitted with a NoiseGard which brings listening to music to another level. Whether you are on a plane or in a noisy street, you can simply and enjoy your music. They ensure only your music gets into your ears and shut the rest of the noisy world. However, to be aware of your surroundings, you can press both volume buttons simultaneously to turn off the feature. The cool thing about noisegard is the fact that, you won’t get excessive ambient noise from your music which is likely to bother other commuters. The active noise cancellation can be activated or deactivated circuitry.
The headphones come with Bluetooth 4.0 with aptX codex compatibility. This ensures the user enjoys unwired and undisturbed music everywhere, everyday. You can get up to 10m wireless range from the transmitting device. However, if you are in an area without physical obstacles, the headphones works well in a range of 20-30 feet. When you move to rooms that are separated by walls, you will still get the same results. If you want a simple and immediate pairing with other compatible devices, you can use the near field communication feature. This futuristic technology gives true wireless Hi-Fi sound. The manufacturer has focused on quality of sound.
Earpads and headbands
The earpads are ergonomically designed to fit around the ears. First, the earpads are thick enough to give maximum comfort when listening for long hours. The sound is so clear as if there’s a sub-woofer hidden somewhere in the earcups. In fact, they give a hint of luxury and passively eliminate room noise even before you engage the noise cancellation feature. Similarly, the headbands have more padding compared to other rivals in the same category. They come with detents which give a secure, accurate ear-to-ear fit. The headbands feature a foldable design for easy storage in the protective case. Once the headbands are locked, they won’t fall out.
Ear-cup mounted controls
The Sennheiser HD 4.50 feature 3 buttons (multi-function, power and volume buttons). When you press the multi-function button once, you can change tracks, adjust volume or manage incoming calls. Likewise, when you press the same button twice, to accept an incoming call, end an active call, toggle between two active calls or redial the last number you called. On the other hand, when you press the power button once, you will activate or deactivate the noisegard. This saves the battery life. When you press twice, you switch the headphone on or off. Further, the +sign increases the volume while the –sign reduces the volume. Once you get your finger at the intuitive buttons you will have control of your device. There is no doubt the earcups have been given attention to details. You can modify the volume, change tracks or switch modes between music and call. The right earcup is fitted with a micro USB connection for the 3.5mm audio cable included in the package.
For a spectacular music experience, the manufacturer has equipped the headphones with a lithium-ion battery. When the noisegard is switched on, you can enjoy uninterrupted music for 19 hours. Similarly, when the noisegard is switched off, the battery can last up to 25 hours. However, this varies depending on your usage and the volume levels. The device comes with a detachable cable which can be used for battery free listening and passive mode. One can also use it to recharge the battery once it runs out of power. The manufacturer has not compromised with the quality of the battery. It will last throughout the entire lifetime of the headphones and is permanently fixed. Recharging usually takes about 2 hours.
The headphones were built with portability in mind. They are not too bulky on the ears and hands well on the neck. Secondly, they are lightweight.
The headphones produce quality music from all genres. They are designed to get the most out of hip-hop, pop and rock genres of music. That said, the music is unnoticeable when playing at low volume. Likewise, the headphones deliver low-frequency response to base which might not be appealing to base enthusiasts. However, when paired with any iPhone device, the base response comes out clearly both at low and high volume levels. When noise cancellation is off, there is a slight shift on the base and treble response. When it’s activated, the headphones give more sub-bass. Overall, the sound effect is well-balanced.
