Offered in black, the cans have a matte finish using silver-colored particulars. The lavish circumaural (over-ear) earpads provide a sign of luxury.

They also work to eliminate a nice swath of surrounding room sound until the active sound cancellation is engaged.

Despite just soft padding on the headband’s bottom, the cans are comfortable, though more extended listening spans, the headband may begin to make its presence known on the surface of your scalp.

Whether the headband feels nice for shorter periods and establishing a secure, proper ear-to-ear fit is simple thanks to detents on the headband’s adjuster.

The reduced external panel of the ideal earcup homes a micro USB link for the included charging cable, in addition to a link for the added 3.5millimeter audio cable.

The cable lacks an inline remote, and this can be a small bummer, but it will twist and lock into position so that it will not fall out, and it is a beautiful layout option.

Sennheiser HD 4.50 BTNC inlineNext to such connections, you will find controls for power/pairing, a multifunction button that controls playback, phone management, monitor navigation, and a volume rocker button that operates along with your device’s master volume amounts.

When pressed on each side, the quantity button allows you to activate or deactivate the active sound cancellation circuitry.

Besides the charging and sound wires, the cans ship with a dark protective zip-up pouch. You’re able to continue to keep the cans powered up to utilize the noise-cancellation circuitry while using the sound cable.

The built-in microphone provides exceptional intelligibility. Together with the Voice Memos program in an iPhone 6s, each word has been crystal clear.

To find the best in the Sennheiser HD 4.50 SE wireless noise-canceling headphones that you want to use in noisy surroundings, so we wore them in-town roads, on a commuter train, and also on a brief flight.

The NoiseGuard noise-canceling tech employs double omnidirectional microphones to track the ambient noise, which it subsequently cancels out.

Judged on audio quality, the apt-certified HD 4.50 BTNCs work remarkably well for the cost.

Having comprehensive, well-rounded stereo audio when connected to some smartphone wirelessly through Bluetooth, they proved more curved with audio than the Bose QC35s, but maybe not as sharp as the Sony MDR-1000X.

A rumbly bass this isn’t, and audio does shed a bit of its luster once the cans are in NoiseGuard style, but characteristic is odd for its genre.

Meanwhile, the NoiseGuard is practical and relatively challenging to criticize. It may fall just shy of the technology found on both the Bose and Sony cans, but it is delivered in a much better-value bundle, and also, the quantity goes high with no distortion.

With affordability comes typically compromise, and we needed to experience this in the kind of limited battery life. On the other hand, the Sennheiser HD 4.50 BTNCs continue for 20 exceptionally notable hours and on a level with Bose and Sony headphones.

In reality, the only difficulty we had was people snug-fitting earcups, that absence of venting; sexy ears are a genuine chance on a hot train or airplane.

Sound Quality

Although I typically like a somewhat exaggerated bass profile, I discovered that the balanced sonic profile in the 4.50 BTNC provided a full and rounded sound without sounding overprocessed. Bass was generally tight and clean, although mids and highs were usually impartial.

Pearl Jam’s Nothingman brought me back to high school, together with Eddie Vedder’s vocals front and center. However, the cymbals and large hats at the backdrop stayed clear from the competitive electric-guitar riff from the foreground.

Comparing these to the Audio-Technica headphones, the Sennheiser 4.50 BTNC offered only a little more presence in Vedder’s vocals in addition to fullness at the instrumentation.

For the following comparison, I listened to the same tune on the V-Moda Crossfade M-100, a nonwireless, non-noise-canceling version, and that I discovered the V-Moda to become more bassy. The Sennheiser 4.50 BTNC is tuned to seem more natural.

The subtle backdrop chorus harmonies on Ultimately Moving by Pretty Lights were easy to pick out with the Sennheiser headphones.

The cans deftly combined multiple components, starting with a recognizable guitar riff made from Sonny Stitt’s Personal Number with a vocal sample from Etta James Something’s Got a Hold On Me Elements of this tune panned back and forth between left and right, with no muddying between stations, although the guitar along with simultaneous bass tune always looped throughout the tune.


The 4.50 BTNC cans contain enough cushioning to be comfortable without putting an excessive amount of strain in my mind. I wore them for several hours at a time with no situation.

The leatherette is also relatively gentle, upping the comfort quotient while at the same time creating a tight seal to help block some ambient sound.

The ear cups are big enough to fit almost entirely within my ears (that can be a little to medium-sized). But if you have more prominent ears, then they may break on top of your ears than more than them.

Installation And Connecting

The very first time I turned on the 4.50 BTNC headphones, they launched into pairing mode and required just a minute to link to my Samsung Galaxy S7. When the first connection was successful, the following connections were equally quickly and effortless.

The 4.50 BTNC features an NFC chip over the ear cup, making it easy to match the headphones using an Android mobile or mobile device.

But if you do not have an NFC-compatible apparatus, hold the power button at the On position for a couple of seconds, along the cans will go into pairing mode. In all of the time that I used this set of cans, the link stuttered just a couple of times.


The controllers on the base of the perfect ear cup played well and are responsive. Instantly gloomy, the multifunction button permits you to pause or play music while directing the spring-loaded button forward or backward improvements or rewinds the trail choice.

I discovered this layout is far simpler to use than rival cans, making users click on volume two or three days to do the same function. The identical button is used to answer and end calls.

I initially confounded the power/Bluetooth button to the active-noise-canceling toggle before I looked in the directions.

But after further study, I found the noise-cancellation purpose could be disabled or enabled by holding both the quantity and quantity buttons at precisely the same moment. But as a result of button placement, this move was slightly embarrassing to pull away.

Active Sound Cancelling

For the most part, toggling the active sound cancellation (ANC) off and on to the 4.50 BTNC made hardly any difference when listening to songs, particularly on louder tracks. But on softer, quieter tracks, there was a faint hiss in the background, which vanished once ANC was permitted.

The Sennheiser cans removed approximately 60 to 70% of the plane’s rumble, but when directly compared with the Audio-Technica cans, they were lacking.

The Audio-Technica ATH-ANC9 was substantially quieter complete when the ANC circuit has been switched on, while there was an audible rumble about the Sennheiser headphones.

Battery Life and Bluetooth

Sennheiser asserts the 4.50 BTNC lasts around 25 hours on a charge. However, that quote describes if the active-noise-cancellation circuit has been switched off.

Together with the ANC empowered, that time is nearer to 19 hours. That meant I needed to control the headphones only three times in 3 weeks. They readily lasted for two 2.5-hour flights, also multiple 3-to-4-hour listening sessions, without having a charge.

It took about two hours to receive a complete charge. The fantastic thing is that, as a result of this micro-USB interface, the Sennheiser 4.50 BTNC may be billed using a mobile battery from numerous manufacturers.

Comparatively, the Audio-Technica headphones utilize a less-convenient, single AA battery to power the noise-cancellation circuit. They, therefore, are believed to last a max of 35 hours on a charge.

In all of the time that I was using this set of Sennheiser headphones, the link stuttered just a couple of times. But they recovered their link relatively fast out to about 30 ft, even letting me walk up a flight of stairs in my apartment building.

But once I reached the border of this relationship range, it paves how my mind has been turned; the Sennheiser 4.50 BTNC will lose and recover link since I moved my head around.


The Sennheiser HD 4.50 are perfect noise-canceling headphones for its long-haul traveler, coming in considerably more affordable than competing versions from Bose and Sony. Sennheiser’s competent NoiseGuard technology and travel-minded design imply these wireless Bluetooth headphones are tough to find fault with.
