It's hard to make a pair of Bluetooth headphones with quality noise cancellation for a reasonable price-we haven't found a winning pair yet. The Sennheiser HD 4.50 BTNC come close, but ultimately there are some quirks that stick out, like the noise cancellation's impact on audio and the slightly...

Strong bass response matched with crisp, bright highs; Bluetooth functionality and active noise cancellation; Detachable cable for wired listening

Noise cancellation affects audio performance; Can get uncomfortable over long listening sessions; Not for those seeking accurate sound signature

There aren't too many headphones out there that offer both noise cancelling and built-in Bluetooth. Out of those select few, fewer again are actually worth your time and effort and attention.

Who says great noise-cancelling's reserved for the elite? Now Sennheiser has dropped the gauntlet on the competition by launching the HD 4.50 BTNC Noise-cancelling headphones. It's much less expensive than the venerated Bose noise-cancellers that dominated Business Class cabins.

Sennheiser HD 4.50BTNC are large on-ear wireless headphones with Bluetooth as well as NFC connectivity

This is my first pair of over the ear headphones so my thoughts after a week. Battery life - Excellent Sound quality - Good I listen to a range of genres for Hip Hop and R&B songs with a lot of deep base these are excellent the only down side is that they aren't very load.

I read many reviews about many headphones before I settled on purchasing these for my Husband's Birthday present. He is extremely pleased with them and finds wearing them comfortable and the sound very clear. I have never purchased headphones before. They have lived up to our expectations.

I have been using these headphones for a couple of weeks now. As you would expect from Sennheiser the sound quality is excellent and the noise cancelling works well, both on its own and when listening to music, cancelling out most of the engine noise on the train and bus.

Supremely comfortable, lightweight and superior sound. The latest wireless offering from Sennheiser does not disappoint. The sound is crisp and clean and with the active noise-cancelling feature, you can blissfully work away and drown out your surrounds. I cannot fault these.

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.

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
