With ample details, Sennheiser HD 4,50 BTNC is an excellent all-around wireless noise-canceling headphone with audiophile-grade sound quality.

A very interesting model, which although costs $172, other models with the same sound / noise reduction quality are much more expensive.

3. Ergonomy

Overall 4.9/5
As with the HD 4.40, Sennheiser HD4.50 BTNC features a rigid, but fascinating design. Refined curves, black matte traditional shades, and overall a neat appearance that is ideal for any attire.
The headphones are incredibly flexible in this regard. With ample details, Sennheiser HD 4,50 BTNC is an excellent all-around wireless noise-canceling headphone with audiophile-grade sound quality. It also embodies the highest-quality assembly and a strong, yet light framework that allows you to listen to music for hours. With only 221 grams on the scale, soft ear cushions that envelop the memory-filled pads are among the most comfortable Bluetooth headphones.

Furthermore, the headsets have a folding mechanism and can pack into a backpack. Most of the time, this is a practical feature that maintains your headphones in good condition whenever you carry them around.

4. Controls & Connectivity


In addition to the headset itself, you have a charging cord, audio cable, carrying case, and documentation in the Sennheiser HD 4.50 BTNC package.

The audio cable layout that features a 2.5 mm jack isn’t too general, reducing the selection of compatible wires. In addition to the audio cable, a rather long USB charging cable supplied that, unfortunately, isn’t USB Type-C. On the good side, the headset works in wireless mode via Bluetooth 4.0 and is aptX compatible. Furthermore, if your device has NFC technology (a protocol used for quick pairing), wireless connections become more intuitive and straightforward.

Sennheiser’s button controls are intuitive. They power the headphones via Bluetooth pairing, offer audio management, and activate/power off the Noise Guard noise-canceling function. For a purely audio set of headphones, the addition of voice assistant via Smart Control App is nice, though not substantial. The Bluetooth connection ensures stable transmission within a range of 10 meters with no interruptions. The controls are simple to use, but a sound signal accompanies most of them, whereas voice commands trigger other functions. You can, however, disable the voice prompts.

The presence of an exclusive audio cable to plug into the Sennheiser HD 4.50 BTNC is beneficial, allowing you to reduce battery consumption. Similar to the ambiguous implementation of B&W PX, where the noise-canceling stays enabled while connected via cable; Here, the control keys do not function when; and the noise-canceling feature is turned on by default. Therefore, if you want to listen without it, after turning on the headphones, you’ll have to manually disable the noise-canceling.

5. Noise Canceling


With ANC and Bluetooth, you will experience 19 hours of peaceful listening time. With active noise cancelation activated, the headset runs up to 19 hours and 25 hours without it. It’s not the HD 4.50 BTNC’s strongest aspect, though it can play music for a week with 2.5 – 3 hours per day on average before it needs to charge.

The shared microphones lose communication quality when noise-canceling is activated failed in Sennheiser’s hi-fi wireless headphones. When on the phone with an interlocutor, the sound is clear, though it has issues in noisy or windy environments, especially with ANC. In this regard, the headset might not be the best nor intuitive, though it has the merit of sounding remarkably beautiful and natural.

Overall, with noise-canceling enabled, Sennheiser HD 4.5 Bluetooth Noise-Canceling displayed noble qualities for a budget high-fidelity headset: clear and detailed high-quality sound with beautiful power and extension in the bass area. It offers a good-quality bass tone. The rest of the spectrum forms a beautiful, detailed musical scenery, although the highs lack a bit accuracy; and sometimes, they become rather reserved.

The noise-reduction si rather competent and can be adequate for a walk in the city, an office, or in-home use. Listening to music at a particularly low volume with noise-canceling activated works out great. Sennheiser’s noise reduction feature, advertised as “Noise Guard”, is practical and well worth it. It can adjust itself automatically depending on the environment. The insulation of the cushioned earpads plays, too, a significant role, improving the listening experience by sealing off from the outer world.

6. Sound Quality

Within a similar design as Sennheiser HD 4.40 BT, what HD 4.50 BTNC offers us is a good-sounding pair of Bluetooth headphones with worthy noise-canceling system and decent passive noise isolation. In general, this is better than anything on the market that costs less than $200.
Sennheiser convinces with highest-quality 32 mm drivers, and despite their smaller than the usual size, we’re thrilled by their output and overall natural musicality. Of course, the drivers’ size impacted the basses, which aren’t as heavy and powerful as that of JBL Live 650BTNC.

On Smart Control App (Sennheiser’s new free headphones app), users can manage, adjust their music via equalizer, update firmware, and configure HD 4.5 BTNC.

7. Conclusion

Overall 4.8/5

In the end, a quite fascinating noise-canceling headphone that offers tremendous value for under $200. If you consider yourself an audiophile or are committed to good-sounding music and require a budget noise-reduction system, then the Sennheiser HD 4.50 BTNC is your choice. Likewise, if all you want is a purely musical experience, then go for HD 4.40 BT; practically the same Bluetooth headset without NC and cheaper.
