Jvc Hanc250 Noise-cancelling Headphones

JVC HANC250 Noise-Cancelling Headphones Review By Vic Kanwar

First all noise canceling headphones will produce some audio pressure in the ears and this is simply to do with way noise canceling works. Neither the Bose nor the JVC produce any annoying amplification hum found in many noise canceling headphones. The Bose QC2 are over the ear and just the physical design cuts out a large amount of ambient noise, the active noise canceling takes care of the rest. The audio reproduction is like most Bose products excellent, good bass and sparkly highs and missing in the middle. But you live with the discomfort of over the ear design (my ears lobes get hot) and relatively large bulk.

With the Noise canceling standard set by the QC2 Bose had to take a much more aggressive approach for the active part of Noise Canceling for its over the year QC3. The QC3 do an excellent job (actually better then the QC2) of canceling noise. The downside for me is the extreme audio pressure exerted by the noise canceling on my ears and I can’t keep them on for more then 15 minutes (I feel the discomfort in 15 seconds) but every one is different in their tolerance.

Now to the JVC HA-NC250 with an over the ear design but slightly larger then the QC3 the JVC ear pads do a very good job of dimming the sounds. But with noise canceling off you can hear most common sounds (kids, TV, fridge, furnace). Switch on the noise canceling and something strange happens all the low frequency sounds just vanish fridge, furnace or in a plane the jet engines you can still hear the kids and TV (till you switch on the music). The other big difference for me is I feel no audio pressure and I have kept them on for hours. Bose with the QC3 eliminates a much wider frequency range then the JVC but introduce much greater audio pressure in the process. The JVC are more targeted for the low frequency hence cause less discomfort. If you are looking to use the headphones in a noisy environment and can bear the audio pressure the QC3 have a slight edge but for plane travel the JVC win hands down. My wife just took them on a 16-hour flight (that’s in the air 16 hours non stop) and never took them off and felt no discomfort.

With noise canceling on the JVC are better then the QC3 with good tight bass, clear mid range and crisp high end not as sparkly as the QC but more similar to the Bose non noise canceling over the ear headphones. The JVC will work with the noise canceling off (in case you run out of batteries) the Bose will not but the sound quality will suffer. Buy a 15 minute quick charger and a bunch of AAA rechargeable batteries.

Though you won’t get the envious looks from other passengers that you would with the Bose but for about the cost of one QC3 a family of four can have the same comfort and sound quality as you get with the Bose. At the same price I would take the JVC HANC250 over the QC3 but at a fraction of the cost this is not even a contest the JVC wins.

How Do Noise Cancelling Headphones Work?

Noise cancelling headphones are useful to block out noise in noisy environments like trains, buses, and public places. The technical theory that is worked out is that this device copies the sound waves from outside and then they make these sound waves go out of phase. It can be also compared to that of swimming upstream. If a river’s downstream current is directly proportionate to your upstream swimming strength, then you stay still. In this case, the device stays quiet!

 

 

There are two models of noise cancelling headphones. Over-the –head headphones are a little larger and less compact but the Earbud headphones are compact and can be carried around in your pocket.

 

 

There are two types of headphones designed to reduce the interference of the noise that is created in the background. They are the passive noise canceling headphones and the active noise cancelling headphones. Passive noise cancelling headphones work on the theory of muffling the external noise or sound to lessen the interference with music or recorded speech. Active noise cancelling headphones on the other hand, electronically decrease the external sound and produce a quiet and calm listening environment.

 

 

Passive headphones essentially utilize the muffling characteristics that are provided by circum- aural headphones. It is designed like a cup with the rim surrounding the ear. The rim constitutes of high- density foam and sound dampening material. It is soft and doesn’t hurt the ears and it creates an acoustic seal that has the capacity to block 20 decibels of noise.

 

 

Active noise cancelling headphones are a more advanced version and have the potential to reduce 20 decibels more noise reduction than the passive model. It uses the phase cancelling technology in its working. This is the main key feature of this model. It works by using a microphone to pick out the external noise which the circum- aural cushions are unable to prevent or block out. The frequency and the intensity of the external noise are analyzed by the phase canceling circuit and it generates a mirror image of the noise. The noise created is 180 degrees out of phase.

 

 

The speaker of the headphones plays the anti-noise along with the music or recorded speech. The artificially generated anti-noise is exactly the opposite of the external noise that has entered the device and so when the two noises meet they cancel out each other. The end result is that the volume of the external noise becomes extinct and the audio you are listening to becomes very clear and audible.
