I had owned a pair of these for at least eight years without a problem, and only replaced them recently because the covers on the earphones were deteriorating (this seemed like normal wear). JVC may have replaced some parts with plastic that's not as durable.
These headphones are perfect for my transcription side job, which I do from home. They cancel out the sounds of my neighbors, my fiancée and friends watching football, and the whining of cats.
An ON/OFF switch on the sets strengthens the cancellation of ambient noise. When you switch it on, it honestly sounds like you turned up the volume inside the headphones significantly.
There is a cool retractable cord feature helpful for swift folding and returning to the carrying bag (dust and scratch protective) included.
Finally, they are super soft from the bottom of your ears to the top of your head due to double foamed cushioning. Who doesn't love soft?!
This headphone is also sturdy and folds flat. Easy to travel with.
My only complaint is that the cord, which retracts into the headphone, barely reaches if you sit in one of those 'Comfort' seats on Delta. The headphone outlet is on the seat in front of you, which is a bit of a reach. The cord will reach, but there's little slack. Still a 5 out of 5 for price/performance/convenience.
