Good neutral sound. Like to collapse them. Not the most comfortable naps. Works well for a few hours, then it's nice to take them off. That works well for the daily commute. Battery life seems good. NFC to connect works well and is convenient.

For a price of around 199 euros, Sennheiser offers an enticing package with the HD 4.50BTNC, combining quality sound, functionality and convincing performance into one neat product. Even better, you'll be able to find the model in specialist shops at an even lower price of around 140 euros.

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.

I wear them all the time while doing yard work! A lot cheaper then some of the others and sound just as good.

Yes, if you are looking for a top-end noise cancelling headphone. At the moment this is among the best you can buy and comes with the added advantage of being wireless and versatile enough to work with all kinds of sources from laptops to smartphones. Go ahead, this is a good choice.
