The thing about Bose is that the noise cancellation is superior to the knock offs. They are, perhaps, $250 worth of noise cancellation and $50 worth of headphone.
I bought some “Shenzhen Special” noise cancelling earbuds off of Amazon for what seemed like a good price, and after I bought them the company sent me an email warning via Amazon that I shouldn’t compare them to $300 Bose noise reduction, which turned out to be very true. The active noise cancellation was almost subliminal :-/
The Trelab Z2s might be ok, but if you want active noise cancellation, off brands may not be the way to go. If you do decide you want to buy these “bargain” headphones, you may want to pony up another 10 bucks and buy them from Amazon, so that you can return them if you don’t like them. (All products sold on the BoingBoing store are all sales final.) And BoingBoing auto converts Amazon links in comments into Amazon affiliate links to BoingBoing’s account, so you don’t have to worry that BoingBoing won’t get a commission if you buy from Amazon instead of the BoingBoing store.
