Not everybody can afford a premium wireless noise-canceling headphone, which is where Sennheiser's more budget-conscious HD 4.50 BTNC Wireless comes in. At $200 (￡170, $AU329), it's not cheap, but it's less than what you'll pay for certain models from Sony and Bose -- and Sennheiser, too.

The Sennheiser HD 4.50 BTNC Wireless is wireless noise-canceling headphone with effective noise canceling that sounds great and costs significantly less than Bose's QuietComfort 35; It works well as a headset and offers decent battery life; The headphones fold up into a simple canvas carrying bag

Not quite as comfortable as higher-end models from Bose; Sony and Sennheiser

Sennheiser promised to deliver on several new headphones and earphones and the most anticipated so far is the . The entire line of Sennheiser HD 4 Series headphones is a relatively new approach that focuses on a more robust sound in a comfortable and portable headphone.

These allow you to run them with the cord if the battery dies. That's a handy function! --Noise cancelling is sufficient. Once you make it to the Bose, Sennheiser, JBL group of cans, the playing field is more about preference.

Active noise cancelling Low price Good sound quality

2.5mm cord on the can side, 3.5mm on the phone side; Use the same size on both sides! 3mm on a 40mm thick can is a drop in the bucket

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.

These headphones have been great so far. Battery life is insane and sound quality is better than I would expect for a $100 pair. Bluetooth range is really long, and you can also plug these directly into your computer using the aux that comes with them. Bass is really crisp, but not super heavy.

I've had these for about two months. What I like about them; battery life is excellet, they can remember bluetooth pairings for up two eight devices which for me is really practical, phone, tablet lap top ans when I get one that has bluetooth TV .

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.

Returned these the next day. Noise cancelling and volume extremely poor. Could hear the microwave as well as conversations even on the highest volume. Along with this, the volume was not loud at all, in an empty, quiet house these still made me feel like I was wearing the apple earphones that came...

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.

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 [...]
