Pros I cant think of anything good about these head phones
Cons Large heavy cancelling device unit, uncomfortbale, harldy any noise cancelling
Summary I bought these from the store in Heathrow Airport UK, I texted a service that gets information about anything 6336 and asked them if they were any good. They told me yes. They lied.
These headphones claim to cancel out 85% of the external "noise". It is a lie.
All they do is slightly amplify the sound, thats it.
Do not buy these headphones. The Phillips SHN5500 headphones are uncomfortable, clumsy and a total rip off.
"reasonable sound quality , poor noise cancellation and VERY uncumfortable sfter 10 mins use"on by tamanduta
Pros cheap purchase price
Cons comfort , noise cancellation
Summary Purchased the Philips SHN5500 Headphones primarily for Air Travel. Unfortunately the behind the head set up pushes the headset off your ears when seated in an airline seat. Ear loop fitment becomes uncomfortable pretty quickly and the Noise Cancellation function does not live up to my expectations. I still use them for commuting but will be looking for another type of Headphones for travel, probably the full ear cup type.
You get what you pay for.
Pros Good sound quality when not using noise canceling
Cons Almost no noise cancellation, just boosts the sound
Summary Good sound and would have been a fine pair of headphones if Phillips didn't add in poor noise cancellation
Pros Good sound quality if used as standard headphones
Cons No noise cancellation at all. Turning on increases sound volume but exterior noise remains same level. Turning down volume to match level when powered off and the noise level is exactly the same.
Summary Completely disappointed. Don't buy if you are after noise cancellation feature as I was. So disappointed I registered on this site just to express my view. Will be complaining to Philips to get a full refund as product does not live up to there claim of 70% noise reduction. In my opinion, the only noise reduction is through amplification of the sound to reduce the noise to sound ratio.
Pros Decent sound, comfortable, low-frequency humming reduction
Cons Bulky control, requires batteries to work even with noise-cancelling switch to off. The sound is attenuated when NC is turned off.
Summary It is hard for me to give an objective opinion on the noise-cancelling feature (NC), since this is my first device with such a feature, but my first good impression was formed while I was driving back from the store where I purchased it. I put the headset and turned the NC on (without plugging the jack to a sound-source) and I noticed that the sound of the engine and the vent was attenuated. In a silent environment a distant humming background sound produced by the headset speakers is audible, but as soon as environmental sound kicks in, that is the sound that cancels it. The effect of the NC becomes obvious when you disable it after some time spent in a noisy environment - the noise becomes louder. The same way, my perception was that the music playing on the car radio became louder, obviously because the noise that was masking it got attenuated by the NC. Again, the set was NOT connected to any sound source at the time.
To be clear: it does not mask speech, music, ringing phones and other office noise - but it is effective against low-frequency humming sounds produced by engines, air-conditioners, server vent noise etc.
The sound quality is quite decent. Wide frequency range with warm bases, nice sound resolution, but in order to enjoy in all its glory, the NC has to be turned on.
