Sennheiser HD 4.50 Bluetooth Wireless Headphones Review
Sennheiser recently added to their excellent noise cancelling headphones line-up with the HD 4.50 BTNC. The wireless headphone is their mid-range offering. Sennheiser haven’t cut any corners though, and it has many of the features of more expensive models. The HD 4.50 BTNC features wired and wireless operation, 19 hours of battery life with noise cancellation on (25 hours with it off) and a broad frequency response of 18-22,000 Hz. It’s comfortable, sounds great and is easy to use. There’s a few issues here and there which we’ll discuss, but overall the design and build is very high quality.
The HD 4.50 BTNC offers great audio performance, especially for the price. It has a punchy, bass-focused sound that remains balanced enough to work with a variety of styles. It has a detailed response and you’ll notice little things with this model you won’t hear on other set-ups. The flagship Sennheiser PXC 550 undeniably sounds crisper and more detailed, but you have to A/B the two headphones to notice it. You can hear all the details in the drums and the guitars. The rhythm guitars and vocals are brought forward in the mix, and the bass guitar sounds thick and full. For something different.
Available in black, the headphones have a matte finish with silver-colored details. The plush circumaural (over-ear) earpads provide a hint of luxury, and they also function to passively eliminate a decent swath of ambient room noise before the active noise cancellation is even engaged. Despite only light padding on the headband’s underside, the headphones are initially comfortable, though over long listening periods the headband can start to make it’s presence known on the top of your scalp. Regardless, the headband feels fine for shorter sessions, and setting up a secure, accurate ear-to-ear fit is easy thanks to
detents on the headband’s adjuster.
Sennheiser’s NoiseGard noise cancellation circuitry is quite effective. These headphones are also far less expensive. Like most inexpensive noise cancellation circuitry, it produces a very subtle but audible hiss. That said, the hiss is far less audible than it often is, and it’s not unpleasant in the slightest-think of it as exceptionally faint tape hiss-and it’s unnoticeable when music is playing at even low levels. The noise cancellation effectively tamped down powerful whirring AC noise, and will be effective on planes and trains.
The Sennheiser HD 4.50 are comfortable and well-padded headphones that feel a bit tight on the head. They’re decently lightweight with ear cups that fit comfortably around most ears. The padding on the ear cups especially is thick and soft
These headphones have a stable wireless design that won’t easily fall off your head. The firm swivel hinges, combined with the wide headband, and broad ear cups prevent the headphones from swaying too much even during physical activity. They won’t be the best choice for exercising or intense sports but the stability they provide is decent enough to jog with. The wireless design also removes the chances that the headphones will be yanked off your head because the audio cable got hooked on
The most important thing about a new pair of headphones is how they sound, assuming they’re not a total disaster in the design and comfort departments. So how do the Sennheiser HD 4.50 BTNC headphones sound? Pretty good – but there are a few things to consider. Let’s start with the bass, which is deep, powerful, and smooth. Bass-lovers will enjoy the amount of bass
on these headphones, though it doesn’t stray into mega bass territory – which in our opinion is a good thing. One thing is for sure- the sound profile isn’t necessarily natural, and that shows in the bass perhaps more than anything else.

Should you buy it?
Sennheiser’s HD 4.50 BTNC Bluetooth noise cancelling headphones definitely sit on the cheaper side of the spectrum when it comes to that one-two punch of wireless and ambient noise reduction. That makes them attractive in the first place. But then you add their pretty good sound quality– better than competitors with stronger noise cancelling– on top of that, and the proposition becomes even more attractive. Unless you need that super-strong noise cancelling, or if you plan to wear your headphones for several hours at a time, you’ll be happy with the HD 4.50.
• Bass-focused sound that retains balance
• High quality for the price range
• Easy to use
• Strong bass response matched with crisp, bright highs
• Bluetooth functionality and active noise cancellation.

The Sennheiser HD 4.50 BTNC is an excellent entry into the wireless noise cancelling headphone market. it’s the best headphone of its type at the $200 price point. It has a powerful audio response with plenty of bass (but not too much) and is fairly comfortable and easy to use. The headphone’s noise cancellation performs well and while it’s not built like a tank, it’s certainly tough enough for everyday listening.
