Cheap active noise cancelling earbuds. Big and ugly, but cheap and apparently with decent ANC performance.
Plenty of reviews out there, some are obviously sponsored, but some are from the larger outlets. All pretty much says similar things, big and ugly (with a huge case), but good enough for the price point ($100 USD range) so I guess you can't really go wrong at 50, even if its 2 years old.
Isn’t this RRP?
