Minelab Vanquish 340, Tesoro Silver uMax, Compadre, and BH Tracker IV.

Ex: White's Spectrum XLT, Tesoro Cutlass II Umax, and that circa late 70's red handled junk from RadioShack that started it.
are you certain it is 16 ohms?

higher ohms equal better tone/frequency responce.

I just checked web site and yes 16 ohms.

unless you just wanted the ambient noise reduction of the padded muffs,I would send them back.
or sell them to someone that says the ohm's do not matter.

the closer the speaker ohm to the device specified ohm means better efficiency of the supplied electrical
current(your batteries may last a couple of seconds longer,and less emf bleed off wich is minuscule anyway).

when I upgraded from my old koss phones (100 ohms) to ratphones (150 ohms) I noticed a definite
increase of tone quality(like analog tv to hdtv to my ears).maybe the koss had material degradation over
time that I never noticed but most crucial would be that the r/p's has a better build of materials.

field test the phones and see if they work for you,everyone has there own preference.I just received
a pair of rattlers(same company) and they look like decent quality to me(no field test yet).

Your Jolly Rogers have volume adjustments, correct?

Volume adjustment is achieved by placing a resistive POT in the circuitry. This potentiometer varies the resistance (ohm value, ohmage, not homage) in the circuit path to change the signal amplitude, or in audio terms, volume.

There is a simple resistive circuit (shunt) in any decent audio path between source and output known as the impedance matching circuit that allows for maximum signal strength with minimum signal disturbance between the source (audio output of machine) and the load (headphone/speakers) used for your equipment.

Shouldn't be a problem!
