Head phone is very  essential thing to  the people who  have accustomed to  use computer laptop tab type  technological devices. When people use internet and try to  contact with their friends or relative by  using skype or other  services they  have must  need headphone.


Bose product a lot of people have been waiting for: the QuietComfort 35, an active noise-canceling headphone that's also wireless.

At $350 (£290, AU$499), it costs more than the wired QuietComfort 25. But at least it's only a $50 price bump, which puts this around what Beats' competing Studio Wireless costs. (That 2014 headphone has been discounted in recent months, however, indicating Beats probably has something new coming.)

While the QC35 is very similar looking to the QC25 and is relatively lightweight, it is heavier than the QC25, weighing in at 10.9 ounces or 309 grams vs. 6.9 ounces or 196 grams. The one significant exterior design change Bose has made is to widen the headband, which makes for a little more stable fit with

perhaps some added sturdiness.With microphones inside and outside the earcups, Bose says the QC35 senses, measures and sends unwanted sounds to two proprietary digital electronic chips -- one for each ear -- that respond with a precise, equal and opposite signal in less than a fraction of a millisecond. According to Bose, the headphone is also equipped with a new digital equalizing system that
 balances the sound, whether you're listening at lower or higher volumes.

Battery life is rated at 20 hours, which is quite good. However, Bose has moved to an integrated rechargeable battery from the the QC25's AAA removable battery configuration. (Bose's SoundLink Around-Ear Wireless Headphones II also uses an integrated rechargeable battery.) I personally don't have a problem with the change -- and don't like having to buy new batteries -- but some people prefer their powered headphones to use standard batteries so you can swap in a new one should the headphone die, say, mid-flight. Also, rechargeable batteries only have so many charges in them, and while the one in the QC35 should last several years, it's not user-replaceable.

 (By comparison, the Parrot Zik has a removable, rechargeable battery.)

The good news is the headphone does work as a wired headphone if the battery runs out of juice (a 47.2-inch cord is included -- it's slimmer than the one

 that comes with the QC25 and has no integrated microphone). You just can't use the noise-canceling or Bluetooth, of course, but at least you can get some sound

out of it, and the tight seal of the ear cups does provide a fair amount of noise isolation. As a passive headphone, the QC35 sounds decent -- just not $350 decent.

When powered on, the digital processing and equalization features do smooth things out and improve the sound, so it's best used it as a powered headphone.
