Sennheiser HD 4.50 BTNC Over-Ear Wireless Headphones Review: Noise-cancelling headphones that won’t break the bank.

The Sennheiser HD 4.50 BTNC headphones boast an understated practical design along with impressive sound quality that will scintillate your ears. Sennheiser currently offers seven over-ear wireless headphones, with the HD 4.50 BTNC headphones sitting comfortably in the middle of the pack. The result is a pair of headphones that offers premium features and comfort for a modest price tag.



The packaging of the headphones is simple, which made the unboxing process quick and painless. The ear cups are made with high quality soft leather, making them very comfortable to put on, and the adjustable, matte-black headband fits various head shapes and sizes. A consideration for potential buyers will be the lack of padding on the underside of the headband. I found that a short break was required after every two hours of listening since the headband begins to add pressure on your head. Being wireless, the lack of cords adds to the enjoyment and feel of the headphones.

In terms of durability, the headband may feel stiff at first but is surprisingly bendable despite the sturdy build. The quality of the headphones would have been greatly improved if the manufacturer had opted for metal parts on the silver finishes instead of plastic.

Charging the headphones is straightforward, with the charging port open to the air. A rubber seal or enclosure would have been ideal to protect the port against dust, water and other contaminants. Even though the headphones come with one Micro-USB cord, a complimentary powerpoint is left out of the equation.

Although the design of the headphones was well thought out, the case was a disappointment. According to some, the common denominator for a good pair of headphones is the quality of the carrying case. The case for the HD 4.50 BTNC headphones is made out of standard fabric that has no protective qualities. For a pair of headphones on this level, you can generally expect a leather carrying case with a clip-on strap so you can attach the case to your bag or suitcase.



The HD 4.50 BTNC headphones include an integrated microphone for taking and making calls as well as controls to change tracks and adjust the volume. The quality of sound on calls is very clear and the microphone provides crisp audio for the other caller. In my experience, the sound quality from microphones has varied across other brands, so it was reassuring that Sennheiser has taken calling features seriously. An annoying feature of increasing and decreasing the volume is a beep that plays every time you adjust the volume.

Battery life is impressive, providing up to 19 hours of listening with noise cancellation and 25 hours of listening without. Factors that will affect how long your battery lasts include how loud you like to listen to music and the type of music you are listening to.

The bluetooth connectivity was easy to use. Pairing your headphones with laptops and mobile phones was a quick and painless process.

Set up and sound quality

Sennheiser’s NoiseGard™ active noise cancellation does not disappoint. From the moment you put these headphones on, a large amount of external sound is instantly blocked out before the noise cancellation is even activated. The headphones manage to produce rich sound quality on all spectrums, giving you a good balance between the higher sounds and the bass and drums. The headphones showcased a smooth balance, providing the right amount of bass for heavy tracks and didn’t crumble under the climax orchestral music. Listeners who take their music seriously and dabble in a range of genres will be pleased with the HD 4.50 BTNC headphones.


Over-ear wireless headphones generally range from $180-$799. This places the HD 4.50 BTNC in a competitive place, offering great sound quality and modest looks. If you buy into brands or labels, the reputation of Sennheiser for specialising in high quality audio products will be a plus. At the $300 mark, some of the brands you could add into the mix would be Sony, JBL, Bose and Beats by Dre.
