Great Isolation Cans Great For Shortwave Communications!
I've been a fairly dedicated KOSS fan since 1972 with the first purchase of my KOSS Pro/4AA's, and I've been hooked ever since! Then after having bought a couple of pairs, I discovered the KOSS PortaPros. Damn, hooked agin', and loving it!
What brings me here today is my purchase of my first pair of KOSS GMR-540-ISO over-ear circumaural 'isolated' headphones. I bought them last summer, and after about a 40-hour brake-in period that I put ALL my cans through, they sounded great. Better than expected, though well within KOSS's mission statement tag-line "Hearing is Believing!" Though not up to the same audio quality and performance of the admittedly 'Professional' standard of the Pro/4AA cans, the are still surprisingly proficient and nicely dynamic. Isolation is quite good, and with the included boom mic, I'll easily be able to fabricate a PTT (Push-To-Talk switch) for my HAM radio transmissions as well as RTL-SDR radio reception as well. And the price is RIGHT! ONLY from KOSS, THE Original innovators in Hi-Fi stereophones.
They're light, fit right and most of all, sound right! I should have known, of course, that KOSS got it right and hasn't let me down yet. And with a 16 Ohm resistance and a sensitivity of 105 db means that absolutely ANYTHING will drive them, and drive them quite convincingly. Considering how light and confortable they are, extended wearing is a walk in the park, only better.
Pros: Light weight, great style, great isolation and best of all GREAT sound!
Cons: What cons???
My next purchase after I buy a second pair of Pro/4AAs', I'll be buying a 2 pairs of ESP-9s'! (Ever since owning Stax Electrostats, I'm hooked on Stats. Naturally, KOSS electrostats will be my choice when the time comes.
TTFN . . .
