KossQZ-99 Noise Reduction Stereophone, Standard Packaging,Black

Been looking for a headset that was quiet, and had a built in volume control. These are it. The cabling is solid, the volume control is a nice touch, overall construction is good. No fatigue while wearing them for an hour.

Heavy. For a drummer to wear for an 8 hour session, he needed breaks.As an engineer, I can be in the live room with a guitarist while he plays loudly and still monitor the other tracks along with him, so it's great for that.pressure is pretty intense, if you're already having a headache, don't use them that day. Also, posture and neck angle make a difference, because the top is so heavy.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. Also the coiled cable doesn't stretch as easily as you might want it to. It pulls hard enough to unplug them, so get an extension cable.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. You could use them with a metal detector, operating a radio, etc etc. They are also decently comfortable with one ear on and the other ear against the side of your forehead or wherever so you can hear the world while using them if needed (DJ style, but I would not recommend them for DJs only because they do not look cool enough and the cans don't pivot all the way out. If they did, they would be pretty great for that).

I was in the market for a new pair of noise-dampening headphones.These have been pretty great. They do what they say they do, no doubt about that.I use them with my computer, for music, movies/video and gaming.They get plenty loud enough for me, and the sounds are clear.My only real beef with these headphones, is that they are pretty snug fitting.Good, in that it keeps them on your head while leaning over and whatnot, but bad in that it can be uncomfortable.In my case, when I'm gaming and someone is in the room, I tend to only have the right headphone over my ear, and place the left one behind my left ear (so I can hear when people talk to me). This makes my right ear sore after a while (on the intertragic notch). I've tried different angles (the headphones pivot a little) and extending the length, but no use.If I'm wearing both headphones on my ears (admittedly, as intended), then it doesn't bother me at all.I only bring this up, because I've always worn headphones with one side behind the ear, and have never had this happen.But then, all the headphones I've ever owned, have all been pretty loose fitting.Pros:- Great sound. Both volume and sound quality.- Noise reduction is GREAT on these.- Very snug fit. (see cons also)- Seems to be very solidly constructed.Cons:- A little too snug. Wearing them the way I do, causes irritation.- The cord could be a little longer. It's a good length, but a little longer would have been nice.

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.

These headphones protect my hearing in my workenvironment, which is why I purchased these headphones. They weight just over 1/2 lb.And I can plug into my Walkman, Old School. Volume control and a mono/stereo switch! I don't always listen to music but they always protect my hearing.

totalmente inmersivo, si necesitas estar pendiente de algun sonido exterior mejor usa ota cosa. Te sumerge y bloquea todos los sonidos exteriores. Aprietan un poco la cabeza, si eres muy sensible o cabezón busca otra opción.

Bonne qualité +++, très bonne isolation du bruit, portage long terme difficile à cause du poids

Loved it

Got it for my metal detector, very nice quality of structure. I use it 4-6 hours in a row, a bit heavy, but i don't feel any pressure on my head or fatigue.For those who wants to use it as a music headphones, first - check if your player device will be able to handle its 60 homs, if your devise has no equalizer probably you not gonna be happy ;-) My mac plays great, no issues at all. I never go over 60-70% of the volume level. Everything that KOSS published at an official web-page meets with what i've got. So, i would recommend it, but only if you know how to use it.

Im Amateurfunk gibt es Situationen, wo mana.) einen stabilen Kopfhörer braucht und derb.) wenn möglich, die Umgebungsgeräusche so gut wie möglich dämpft.Beides erfüllt der QZ-99 von Koss optimal.Zur beachtung: der QZ-99 ist ein 'heavy-duty' Modell. Für kleineMP3 Player zwar durchaus technisch anschliessbar, der Einsatz istaber eher für andere Situationen gedacht.
