Question: how long is the cord?
Document: I am a very happy camper. As a note, if you need a longer cord to enjoy your sound, be sure to check out theBose 20'extension cable.
It's a bit long, but I didn't find the supplied cables long enough for sitting in my desk chair while working on the computer. The case that comes with these is a higher quality than most headphones in this price range.The first thing I do when I get headphones is listen to Dream Theater's song, &#34;The Root of All Evil&#34;, it has excellent highs and a thump bass, instead of the low, rattling bass, many headphones are pushing these days.
Would be great if it comes with the converter that I can use on airplane. The rest is fine. Good buy as a birthday gift.
Took off a star for the few problems I had with them while they were working and another for how quickly and how badly they fell apart for such an expensive product, given that I got them for the original price ($180) rather than the currently listed price ($120).
They are extremely comfortable. I have worn them for hours at a time and really do not even notice I am wearing them. The headband itself is adjustable so should be able to fit about anyone. For me, when you couple great sound with a very comfortable and good-looking design you have a winner and these are just that. While these are not sound suppression headphones, that is not what I was looking for.
The sound quality is OK for the price of 130 dollars. Mostly used to watch movies on laptop, heavy bass.
The covering on the earpads and on the inside of the band started to tear and shed, the sound cut out intermittently in each ear and the covering on the jack came apart to the point where there were exposed wires.
Sound is just what I was looking for.They are made well. Love the case they come with. I recommend these.
One of the favorite things I own. I had a pair that I loved so much I completely wore them out. Because of the high price, I waited a few years to replace them, substituting one lesser thing after another. When my first pair broke after many years of hard use, I should have run right out and bought another. I'm certainly glad I finally did.
My wife and kids surprised me with a pair of these headphones. I just purchased and reviewed a pair of Sennheiser's that I had bought, but wasn't really happy with it. They caught these on sale at one of the big membership clubs, for 30 dollars cheaper than the price here. I'm admittedly a Bose-lover.
Answer: The initial cord is only like 2 inches long. But it comes with a couple more. I know one is around 40 inches or so. Other longer cords are available.  With the cords this way you don't have to worry about an accident with the cord and ruining the whole headset
