Super Metal Detector Headphones-- Eliminates 90% Noise
3 of 3 found this helpful Bought these headphones for metal detecting gold along noisy streams and creeks with my Whites GMT . They are great ! Used the stereo-mono switch and set them on stereo . Turned the volume on the GMT to max. Used the headphones volume control and set it so I could here the faintest detector threshold "hum". What a differance , amazing !
These headphones have no distortion (only 0.3% ) and are very clear sounding with 102dB sensitivity (these are not cheap 72dB and 32ohm walkman headphones) . 150 ohm ( ohms means electrical power needed to drive the headphone speakers, it has NOTHING to do with sound ) headphones will quickly drain your batteries. These headphones are 60 ohm. , which is what the White's Co. recommends for their detectors .
They totally enclose your ears and have passive noise reduction( reduce outside noise by 90% ). They have a long cord which is needed for metal detecting,you can leave them on when you put your detector down and dig the gold out .
These headphones are heavy duty but you can wear them ALL day . I give them a 10 on a scale of 1 to 10 .
These are outdoor headphones and are very rugged. They were specially designed by Koss for Metal detectors , Racecar Pits , and people working around noisy aircraft . You can buy these on sell but they are a steal at full retail price.
If you use a metal detector and want to block out the noise of Loud cars,people,or water ,so you can hear faint signals from your detector, I highly recommend these Koss headphones . -- Steven M. , Wa. U.S.A. 8/9/10

Top of the line alcohol detector
The C8 is very accurate when used as instructions recommend. Battery (AAA) last long time. Works with your cellphone if you like but not necessary. Tells you time when you're alcohol will be 0.00 . Simple and easy to use. Get one, gives you piece of mind knowing you are not going to be drunk driving.
