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 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.
Excerpt: I've owned these headphones for over two years. They work excellent with noise rejection. Great for editing and shooting while recording audio. However, they're unbelievably tight and uncomfortable on the ears. I've finally sold my pair and will be purchasing a new, different set.
Excerpt: I got the qz99 to replace a pair of Pelter 3m noise canceling phones that died after a year. I never used the noise canceling aspect of these phones,so when shopping I figured why pay $100 more for NC phones when all I need is a good isolation phones I use these when I mow acreage some times up to 6 hrs at a strech on the tractor it's around 70-75db this is vary wearing and dangerous for my hearing so Good isolation is essential .
Excerpt: good sturdy construction. i use them for video field recording and am very happy with the sound quality and background noise reduction. the multi size jack is helpful. they have some weight if you plan to wear them for hours. but they need to be for the noise reduction. and most any full sized headphone will strain the ears in time.
Pros: Comfortable, Easy To Use, Great Sound Quality
Summary: Heavy ,well made,POOR VOLUMN(60ohm)(bad match)on IC-7800 and TS-590.The Yaesu YH-77STA are excellent AT $99.00. But the SANGEAN EU-55 are MY BEST pick. Light weight ,earphone stops so they dont keep changing size.32ohm LOTS OF VOLUME,COPY BETTER THAN THE YAESU A LITTLE. AND 1/3 THE PRICE $37.00 ON Amazon. there are nicer earphones for lots of money,BUT FOR COPPING WEAK DX I really like the EU-55.
