Summary: Some notes from my old days working with industrial hearing protection ... in the morning the headset will be cold, and your head will be warm. As the headset warms up, it will create some air pressure next to your ear that is uncomfortable. To relieve, just occasionally break the seal next to your skin by briefly taking them off to let in some air until they warm up.
Pros: Great noise cancelling considering the price. Much better than any other noise cancelling headset I have tried. My office environment gets loud enough to be a serious distraction, and these block out all background noise. These things work as good as the hearing protection when I worked in an industrial print factory. the headphones are large enough to fit completely over the my ears.
Cons: The weight of these is slightly heavier, but still similar to hearing protection I used to wear in a factory. That means they are much heavier than any other music only headphones I have worn. These things are mostly made for settings where you need sound while in a loud environment, not specifically for great music quality. There are not separate speakers for bass as on some medium to high quality music headphones so the bass suffers for music listening. that being s...
Summary: honestly, the fact that they are so uncomfortable, overshadows all other good qualities..
Pros: Cheap. Fast Shipping. Sound is ok.
Cons: Super uncomfortable... did they test them on bricks? uncomfortable from the second you put them on. Start to really hurt after about 10 minutes. Cannot have them on more than 30 minutes. Its ridiculousness.
Summary: But these were not the pair I ordered. These are nice & just putting on my ears, almost shut out what was going on on the TV. So I know any audio I want/need to listen to while the TV is on, will work great. My problem - I rec'd these instead of the Koss QZ99 Passive Noise-Canceling Full-Size Headphones, Black which I ordered. disappointing because I wanted the less stiff head part and should work better for me & my laptop.
Summary: I work in a security console with ambient server noise and radio crosstalk these headphones are perfect for this environment, I can hear what I need to hear but also listen to music or communicate with other officers at will. Thanks, good value, good service.
Summary: I had another set from the same brand that I was happy with but they wore out after lots of use over several years. I was happy enough with them that I decided to stick with the brand. I don't know if I just picked a bad model or what but I'm not too happy with my new set.
Pros: Good sound. Decent isolation. Durable construction.
Cons: These headphones are uncomfortably tight. It's like putting your head in a vice.
Summary: I have the KOSS 3000 headset which has the same earphone receivers as the QZ/99 headphones. Two key features: 1) They sound good. Full range, not particularly heavy on bass, and not particularly bright on treble, which is ideal for communications grade audio. Solid, clear mid range where all the action is.
Summary: I am a dialysis patient where the TV's are mounted on the wall in front of each patient (about 20). Person speakers offer no protection from the audio of those around you. If they have hearing problems, they turn the volume way up. The headsets I had did not drown them out, often making listening to my personal music virtually impossible. These headphone totally (almost) block out outside noises. I have to take them off to clearly understand people standing beside me.
