Headphones

Can anyone please tell me the differences between headphones specifically for detector use and those normally used for audio.Are the expensive models so much better than cheaper ones ,and has anyone used the wireless bluetooth type.As usual i'll look forward to any replies.
 
The ones made for detector use should have a couple of features not found on home stereo models.

1. A means of switching/changing from series to parallel mode so that they can be used on a wide variety of detectors. This is because some detectors have a series output and others a parallel.

2. They "should be" more ruggedly constructed to withstand constant abuse, wires getting caught on limbs, being knocked off your head etc.

Considerations:

Yes it is important to have the electrical/acoustical aspects high on the list in decision making, but comfort & safety trump those in my opinion. First, if they're not comfortable for the length of time you're typically going to use them, then they're useless no matter how good they are acoustically. If you are in an area where any two legged or four legged critters might harm you, let's not forget snakes, then a single headphone on one ear or open concept over the ear might be your best choice.

A few examples; let's say your hunting an ocean beach, broad daylight, roaring surf, and howling wind, then full coverage ear cans are the way to go. But same spot, same conditions but at night, you're risking your life with full ear cans because you now have no chance of hearing someone approach you from behind. Winter hunting, full ear cans keep your ears pretty warm, but during the summer they're just too hot, so an on the ear or open concept are much more comfortable.

There will be an impedance figure for the headphones usually listed, those in the 60 to 200 ohms are pretty good in matching a variety of detectors. As far as wireless, some people use and like them, and have purchased various makes & models. Battery consumption is probably one of the major considerations in choosing a set. Myself, I'm just not comfortable having an RF transmitter attached to the detector because of interference concerns. But that's just me, and you will certainly find others who are fine with it, so don't let that hold you back from considering it.

I'm sure others will chime in and tell you what their favorite makes and models are, and how well they've mated to the X-Terras.

Could someone ... or has someone rated the brands and types. I am new and would like to see the ratings ...

We rate detectors (we all know the x-70 is king in our world) .... so I am sure rating headphones should be no problem.

Pretty tough with all the variables to be considered,,,We just don't all have the same hearing, some just work better on a particuliar model of detector and of course prsonal preferences come into play..In most case expensive headphones do a better job for most but all are prone to breakage due to the abuse they take..Many have warranties and the like but all differ..I have to admit 20-25 dollar Calrads made for detectors do a great job for me but you may differ....
 
Hi Dave,

As Dan has mentioned there are a ton of variables. Everyones ear canals are different, almost like fingerprints. Put the same headphones on 10 healthy individuals and you'll get a wide variety of responses not just on sound quality but on fit/comfort.

Probably your best bet is to formulate a survey of the forum members with very specific questions. Perhaps you and Sparkie could collaborate and come up with a unified group of questions.

there are some that will spend tons of cash on high dollar headphones that have an incredible dynamic range and platinum coated speaker cones and, and, and they're more or less wasting their money. If you look at the audio output frequency(ies) of a metal detector, it's very restrictive.. sometimes a single pure tone. Not very demanding when compared to replicating the human voice or a full orchestra. Personally, my favorite 'phones are a set of Peltor Aviation's. Peizo speakers and really good sound isolation. I've also been looking into getting a set of active sound suppression 'phones. Save the money that would otherwise be spent on expensive ear gear and put it towards another coil. ..Willy. BTW.. I CAN see spending extra for 'phones that have replaceable cords.
 
Dave I will say this. When I bought my X-70 I had not even thought about headphones. I bought the Sun-Ray Pro Gold, and am very happy with them. Fit my big ole noggin well, and really pick up the faint signals.

I have read good things about the Rats, Grey Ghost, and Killer B's also. Good luck to you with your choice, Beale.
 
I use the Sunray Golds. I have the Ratphones as a spare. The Sunrays are comfortable and the cord allows me to lay the detector down and stand up without stretching the cord. I have the Radio Shack cordless also and they work great as long as you are in a fairly quiet area. The Wireless are good when you are in woods with a lot of stuff to snag the cord.
 
This is a set of headphones I made up for under ten bucks , they are very sensitive ,building your own you can custom fit them to your own ears so your ear goes inside the cup and is not held flat against your head, the speakers are from old telephones.
I mainly use under chin ultralight phones prospecting or in quiet parks etc. and my DIY`s at beach or in strong wind.

Hi BarnacleBill,
You have me a little confused.
Is the RF transmitter the connection from the box to the
head phones. Are you saying that the signal emitted may
interfere with your detector. You obviously use speaker only.
For the rest of the forum, in Australia our #1 headphones are
Koss.
I must be asleep I haven't heard of wireless, but I never
visit detector shops.
happy hunting

In the photo below you will see an example of wireless headphones. The transmitter which is the black box with the cable & plug is usually velcro-ed to the coil rod. The plug then is inserted in the headphone jack just like a normal set of headphones. The headphones have an RF receiver built in that demodulates the RF signal and voila detector tones arrive at your ears.

Now the picture is just an example of a product that uses a lightweight collapsing type headset. There are probably hundreds of types available when you consider some are full coverage cans, on the ear, in the ear buds etc. Then the choice of Bluetooth, AM, FM, or ISM band transmission. The growth of the portable MP3 players & i-pods etc really caused an explosion of this type of product. The Chinese factories are spitting these things out in the tens of millions a year.

Rather than look in a detector shop which may or may not carry them, just point your browser at Amazon.com and type in "wireless headphones" for a search term. If you're really really bored, you can spend hours there window(s):lol: shopping.

My concern with interference is not just that you have a transmitter in close proximity to the detector, but that via the headphone jack cable it is now directly coupled into the detector circuit. I don't want to get into any long electronics discussion that will just bore everyone to tears, but suffice it to say the the transmitter now has a direct path into the detector which bypasses the internal shielding of the detector. Whether or not this will cause any issues has to be experimented with on a case by case basis. In other words, how does a particular headset co-exist with a particular brand/model detector? Let's say you hook up a given transmitter to an X50 and it works fine, hook it up to a Fisher F75 and the display turns into a pinball machine on tilt.:rofl:

As far as headphone use, I have several, Nugget Busters for full size cans, several Koss's, on ear, lightweight open type, some back up Rat Shack full cans, some very old back up White's branded etc. In other words, I have backups for my backups...........I have too many headphones.:lol:
