Koss QZ-99 Noise Reduction Stereophone, Standard Packaging,Black

Wow, just WoW! .. These are like the ear protection we used in the military.. we called them micky mouse ears.. they were hard plastic cups that encased the ears with sound silencing materials lining the inside. If you combined micky mouse ears with the little plastic insert ear plugs you became effectively deaf.. well tehse headphones are like mickey mouse ears with speakers installed. They passivly block external sounds thru extremely effective sound silencing. and the audio is not bad either. 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. and being a bit airtight you might sweat in a hot environment. bottom line is tho i have found the love of my life when it comes to headphones. I really like these headphones, they are high quality construction. They sound great too but i'm no sound expert. They are over the ear.. except they rest on the bottom of my earlobes.. update: july 2015, well the adustable volume makes the left ear drop out.. you have to spin the volume back and forth like your wearing thru the corrosion on the resistor parts so it gets a good connection. The wires are solid.. the connections are solid.. I believe this intermittant left ear connection is in the variable resistor itself.. not in a faulty wire or connection. So sadly we go from a 5 to something less due to they used a cheap part.. which cheapened what would otherwise be a first class product. I know this product is discontinued so perhaps this was why. bottom line is the left ear is dropping out and i have to mess with the volume knob to restore the left ear sounds. i might try the upgraded version of this and pray they aren't using the same part that is failing here.

My all time favorite headset was a Koss Pro4AA, which I bought in about 1972. I have been searching for a true replacement for a long time. I tried a Koss Pro4AA Titanium, and was greatly disappointed. Primarily because they have very poor acoustic isolation even though they are a sealed over the ear unit. I have also tried a vast number of wired and wireless earbud units. The best one I have found was a KLIPSCH R5 neckband unit, which also fails the isolation requirement. All this brings me to the Koss QZ-99.This unit reproduces the high end of the spectrum as well as any unit I have tried. My test playlist sounds the way it is supposed to sound in that range. If I has an equalizer on my iPad to pump up the bass for my preference I would rate this unit the equal of my Pro4AA in its prime. Why do I say that? This unit provides acoustic isolation equal to that provided by my deluxe shooting ear protectors. I can hear my music or my ball game, without nagging my wife to turn down her mystery on Hallmark, or her shopping spree on QVC.This unit is well constructed and well made, read that as heavy. They seem like they will be in it for the long haul. Yet they are well padded in the ear cushions and the headband. I like these headphones. I think you will also.

Excellent quality and very nice sound. The 4 stars is for the weight (very heavy to have on head very long) and the coiledcord is a pain.

Husband loves these while working on the yard. Good sound muffling, while playing radio.

Wanted a budget pair of headphones for my PS4. I've had a pair of ATH-M40x at my PC for years, but the soundstage was unimpressively narrow when plugged into the PS4 controller. I was hoping these would perform well enough, and in terms of sound quality alone, they do.Unfortunately, they're just too uncomfortable for long-term use, and I've replaced them in the short-term with the cheaper Samson SR850, which sacrifice a little sound quality, isolation, and soundstage width to provide an preferably bassy and far more comfortable experience.Pros:Noise isolation is fantasticSound quality is excellent for the priceWide soundstageVolume control knob is easy to use, features notched detents, and does not feel flimsySturdyCons:Heavy and bulky, especially to put on and removeInitially comfortable, but a little too snug and a little too warm for long-term useUnderstated low-end expression limits practical applicationsNeither:In-line stereo/mono switch is a strange feature to include on headphones, no?Owing to the modestly respectable sound quality and noise isolation, this might be a decent option for beginner bedroom production or as a backup pair, but it's too uncomfortable for a "professional quality" daily driver that sees more than an hour of regular use. There isn't enough going on in the bottom end to recommend it for quick casual use for gaming or other media.If you're looking for decent quality phones that don't emphasize the bassline and only need them occasionally; if you don't mind chunky phones that offer a thinner sound, then these might fit the bill. I think the majority of people should look elsewhere.
