I need quiet as much as music sometimes so help me please


I know nothing about headphones. Mostly because to me they feel uncomfortable and restricting after about
10 minutes of use. But I need something while flying that will knock out as much noise as possible. I use
foam earplugs and they help. Now I am ready to spend what it takes. Questions-
-Is noise cancelling a viable concept?
-Brands to focus on- Sony, JCV and Bose- or so I have been told. Others?

I am having trouble finding any ratings of db reduction specs. Do they exist?

Anyone been down this way lately?

Thanks

The Sony's are almost as quiet as the Bose and have much better SQ. Usually available cheaper.
Better app (Headphones) too.  V2 is OK for sound but starting V3 they have USB C fast charging. All batteries last ~ 20 hours.
In business class they are by far the most common. Leave the audiophile stuff at home where it is quiet.
Do they have heavy duty versions for us rabble in economy?
I bought a pair of the Sony 1000 4's today. 
Got very lucky when the guy at Best Buy
said he owned the Apple $500 model
and it was pretty excellent with interfaces 
with other apple stuff. But the case was a joke
and he admitted the Sony may be better with
noise control-my main concern. Now I see
refurbs with 2 year warranties for $200 on eBay.
Anyone tried those backwater sources?
Since eBay now hits your bank and you can't use Paypal, I would think twice. Other backwaters, Amazon Warehouse, Woot, and dealer closeouts are potential options for similar deals. I have deals at musician suppliers like Sweetwater, Musician's Friend and Guitar Center. Cheers,

Thanks.
I will return the BB pair at $340
for the refurbs at 200 with 2 year
warranties.
