TDK WR700 wireless headphones

Hi all, I have just started using the TDK wireless in the field. I thought I would report on them for anybody interested. First off, these aren't blue-tooth so they aren't plagued by any delay.
They operate in the 2 GHz range. They have no discernible background hiss through my tinnitus. The headset and transmitter link up much faster than Blue-tooth and when the headset is turned off, the transmitter automatically turns off.
The headset has a built in volume control. However the volume control down on the Sovereign has to be turned all the way down to eliminate overload signal on all but the surface targets. It doesn't hurt the ears because there is a limiter in the headphones for overload signals. Its more of a matter of taste and how you like to hear the Sovereign tones. The deeper targets sound fine but can be overloaded by turning the volume up on the Sovereign. It doesn't help hear the deeper signals, just makes them hit a lot harder. The transmitter looks like a miniature mailbox. The transmitter and headset take 2 AAA batteries. If I didn't have 2 years warranty left on my Sovereign box, I would disassemble the transmitter and embed it into the box and draw power internally. The only problem I found out in the field is that the headset bridge occasionally wants to fall forward when you bend down to dig. The headphone cuffs ride on the ear but during a 3hr hunt yesterday I didn't have any ear pain that is associated with some headphones..

While these could be better designed for sports (active use), they are worthwhile change for those that are fed up with ripping the phones off their heads while popping a plug. I won't be going back to wired unless these break.
I will try to answer questions for those interested in going wireless with the TDK's

In a hot tropical climate with a shady hat on the head the THK headphones are worn around the neck with the speakers turned forward.
Sovereign audio is set to normal threshold level and the audio volume adjusted to suit on the TDK.

TDK is not a sponsor of this forum it must be bleept and look like this #$^%$@$:crylol:
 
I got an inline volume control from Radio Shack (Is RS a sponsor?) and it completed the ensemble for the Minelab Sov (Is Minelab a sponsor?).

The TDK's have a problem...they shut off after 30 seconds of silence. When digging a target, they will occasionally shut off when the Sov is nulled.
Not a biggie but can screw someone using silent search. The batteries last a crazy long time but I will be purchasing some rechargeable AAA's in the future.

One other user claimed a delay but I'm pretty sure any 3rd party wireless setup will have a delay if the coil is swung too fast. I personally haven't observed a delay when swinging the Sov.
They also have issues with wind and road noise. They are great for the Avg user like me but for serious detecting I think the purposed wired phones will give any user an edge over wireless at this time.

[i]I erred[/i] when I said they shut off after 30sec. I had the in-line volume too low. I guess the headphones weren't getting enough input signal and they shut off.
Since I turned up the in-line volume, they haven't shut off on me.
