I have never bought any quality headphones before and not sure if there exists noise inhibiting headphones so need your recommendations. The price is not a problem but would be interested in the least pricey and most effective option.
From all the options I've seen, I've only been 100% convinced by high-end Bose headphones (
QuietComfort 3).
As far as I'm concerned, it was the most satisfying solution, noise cancellation is simply mind blowing. And to answer your question: yes, it works. In a house party with 50 people crammed in a 40m2 apartment and music to full volume, I wouldn't hear a single noise except for the person talking directly to me. On a plane sitting in the back, next to the extremely noisy reactors, I wouldn't hear a thing except for the flight attendant speaking to me. It does need a battery to work, but from what I've seen the battery will last for months, despite everyday heavy use.
The downside is pretty obvious, they're ridiculously expensive. I mean ridiculously expensive (400euros here in France, that's approx, 520$).
Also, a little pet peeve of mine: The Beats are good but ridiculously over-priced. Simply because they stamped the name of some rapper on them does not justify the extra hundreds of dollars.
Personally I use the Bose quiet comfort 15. They are awesome for low pitched noises, not so good with high pitched but they do help.
I can relate, and I agree... somewhat.
Low-pitch noises are filtered
better than the higher-pitched ones. But this has more to do with selecting which sounds are noise and which should be unfiltered. The higher-pitch noise (on the QC3 anw), and by noise I mean undesired sounds, are usually well handled.
