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 at $200 USD ($299 AUD £169.00). Sennheiser haven't cut any corners though, and it has many of the features of more expensive [...]

Bass-focused sound that retains balance High quality for the price range Comfortable Easy to use

No hard case

Great sound, as one would expect from Sennheiser. Ample bass from the drivers. The earcups are comfortable but their oval shape gives a little bit of an on-ear feel than I would have liked. If I fit them perfectly over my ears then I get the over-ear feel and comfort.

The Sennheiser HD 4.50 BTNC offer a nice design, are reasonably comfortable, and sound great. Sure, there are better noise cancelling headphones out there - like the Bose QuietComfort 35 headphones.

Work great, use it on my commute in Mumbai and this almost blocks all noise. The battery life is good, one complaint is that the device goes off at about 20%, now I dont wait for it to drain till 20%. The sound quality is good.

Since today is the beginning of the last month in 2017, I think it makes sense to take a look back at everything that has happened this year. For me, there has been a lot of changes, both good and bad, but it has been positive overall.

Picked these up at the Black Friday sale for a good price. Really good pair of Bluetooth headphones at this price. Great sound quality. NC is pretty good too, although not as good as the Bose QC35 obviously.

PRO: For the price point of $250, plus $30 for extra warranty, these are great value headphones; They have really good, clear and crisp audio with good depth; The noise-cancelling works great; Also, the 4-year warranty is incredible (i got an extra 2 years)

CON: Ease of use could be improved; Ease to connect for the first time on a device, I found difficult on some devices

The HD 4.50 BTNCs are significantly cheaper than noise-cancelling headphones from Bose and Sony designed for business travellers, while Sennhesier's NoiseGuard tech proves almost as effective. Thrown in a travel-friendly design and these wireless Bluetooth headphones are hard to argue with.

Great noise cancelling; 20-hour battery; Travel-friendly design; Surprisingly affordable

NoiseGuard tricky to activate; Headband lacks padding; Ear-cups lack ventilation

Noise cancelling is good

Sound quality could be better

Sound 5/5 Battery 5/5 Microphone 2/5 I use those headphones 8-10 hours 5 days a week sound quality is amazing, battery very good, few minuses ears gets sore when I used them for too long also head a bit sore from a headband, apart from that great product for the price.
