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.

Comfortable to wear except they get a bit sweaty if exercising. Noise reduction is good but not great. If is hard to tell if the noise reduction is on or off. The blinking light is the same for both. You have to try them on each setting to tell whether it is on.

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.

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

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 .

It's just what I needed for my gym workout. Works so well and it's lite and easy to use. Price is in the middle range and worth every penny.

"On my second pair in less than 2 months what a joke, the muff has fallen off again. Not fit for purpose I mean cmmon my £20 headphones lasted a year and the sound quality for value for money avoid these theyre rubbish.

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.

Noise cancelling is good

Sound quality could be better

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
