What customers say about "Size & Weight"

Sennheiser HD 4.40 BT

The earphones have a range of movement that is adaptive to the shape of your head, and the headband is elastic and extends to the right size of your head.
The HD 4.40BTs fold for compact storage, which is very nice.
They are pretty light weight and fold into a really compact shape.
They're compact and fold down for easy storage in whatever bag I have handy, and even larger pockets on the right kind of jacket.
The price is accessible, the headphones fold up nicely and are compact enough to pack. They sound great and are very light, with good noise isolation.

Sennheiser HD 4.50BTNC Wireless Headphones with Active Noise Cancellation

Ear cups are comfortable. Weight is minimal.
The weight feels nice and when you fold it, it doesn't feel like it is going to break.
The appearance is modern, streamlined and stylish, with a quality "feel", and light weight, for long term wearing comfort.
I think I have an average size head and the headphones was very tight out of the box for me.
The cups are simply too small for my ears, so they really worked as on-the ear rather than over-the ear.
Uncomfortable on larger sized heads.
Very uncomfortable due to small ear cup size.
They fit my wife much better, but were just too small for me even though I have a fairly normal size head for a man.

What customers say about "Features"

Sennheiser HD 4.40 BT

The Bluetooth connection works great, and I didn't encounter any disturbances or disconnections whatsoever.
Despite many reviews, those headphones are extremely comfortable for my ears, I like controls, ease of connectivity and battery life.
Good sound quality and Bluetooth connectivity works great but that's where the good stuff stops.
The sound is very good, showing a solid mix of highs and lows and not lacking in any frequency.
The connection will randomly drop, music will sounds as if it's skipping, or the volume will drop for no reason.

Sennheiser HD 4.50BTNC Wireless Headphones with Active Noise Cancellation

I love the Bluetooth for when I am at the gym.
Ease of use is the same as any other Bluetooth set. The HD4.50 supports NFC so pairing the headphones with a smart device is incredibly simple.
Bluetooth connection is super good and worked over 40ft distance without any issues.
Range is amazing. No problem going from my phone in the basement to the headphones on the second floor.
Sound is good, although the sound frequencies seem to sound quite different with noise cancelling off/on.

Range is great and the battery lasts for days with 24hr use advertised. If you are using them for bursts they are gonna last along time which is huge for me.

Battery life seems great. Haven't had to charge them yet but they've held up for several long writing sessions.
I love the sound, the range, and battery life of these headphones.
Charging is very long and after a month the battery does not hold well charge.

Battery lasts very long time at least 20-25 hrs per charge.
The active noise cancellation works pretty well, and the battery life is really good.
Great comfort. Good noose cancellation, amazing battery life.
The battery life surprised me.
The 25 hour battery life is also great for commuters like me - I have used the headphones pretty regularly since I got them two days ago and they haven't died yet.
