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.
