Quotes from the Reviews - What People Say about:

Cable

Cable:
"This means if anything damages that cord, you're going to have to perform surgery or dump the headphones."
_
"Also the coiled cable doesn't stretch as easily as you might want it to."
_
"They feel like they will last a good 10 years, but the strain relief where the cable meets the left phone, that is where the problem is going to be."
_
"The only problem I have is that the cord is very long and gets in the way sometimes but really no big problem"
_
"The cord is nice and long, but at the same time, I wish it weren't hard-wired into the headphone set."
_
"The coiled cord is good for keeping the cord out of the way."
_
"They feel like they will last a good 10 years, but the strain relief where the cable meets the left phone, that is where the problem is going to be."
_
"the cable is curly so it does not get caught up in my chair's wheels or drag on the floor.. yet it has the reach where i can stand up and move around the room a bit so i love the cord.. love the headphones.. the ONLY draw back is they do put some pressure on your head."

Comfortable

Comfortable:
"I have been unable to wear them for extended periods because they are not very comfortable, even after tweaking them for a better fit."
_
"However - if you buy them solely to listen to music and expect to have a pleasant and comfortable experience - you're very likely to be very, very disappointed..... and if you plan to use them while operating potentially-dangerous power equipment - you are a complete moron...."
_
"They are comfortable and have great sound quality... only downside for me is that they are so big, they take up a lot of space in my everyday bag..."
_
"But I have found out after hours of wear that these cans are comfortable, and easy to put on."
_
"PROS:* Great value....more noise suppression at 1 8 the price of Bose* Cancels office noise when used with low volume music* Music sounds great* Sturdy construction* Comfortable yet snug fitting ear muffs* Macho look of big KOSS letters on ear muffs....much better than office dweebs with wimpy looking ear budsCONS:* None found thus far."
_
"Love these very comfortable"
_
"Bought to use at the race track my wife loved them comfortable to wear good sound,great price"
_
"Worked well, comfortable, good isolation"

Control

Control:
"However, after ~3 months the volume control became erratic and at ~6 months I totally lost the left channel."
_
"If the volume control didn't fail II might have given them 4+ stars."
_
"Love the on ear volume control so I can turn them down quickly if necessary."
_
"The volume control is very important and works great as well."
_
"All these complaints, I still give them 5 stars because they block out the sound, have local volume control (that knob on the side) and sound decent."
_
"Great for use on large mowing equipment, volume control is easy to use with gloves, better built than other headphones at twice the price."

_
