Mine sound thin and sibilant directly out of my player (Pioneer XDP-30R) so I know what you mean there. It should have enough power to drive them just fine but it just doesn't do it for me. Out of my tube amp though they come to life. They don't have the speed of my other cans so it can get a...

I think you'll be satisfied. I got a set a couple weeks ago and now that they've racked up some hours I think they're great for the price. Quite a neutral sound with good range and detail, and at least for me they're comfortable to wear for hours. I had never heard of the things but after...

I got a chance to try out PX100s at Sennheiser's booth at EAA Airventure last summer and those words describe how I felt about them. To each their own, I suppose. For certain genres of music I much prefer my Portapros to my KSC75s.   Quote:

Precisely. The Portapros sound a bit different depending on the temple pad setting as well.

The KSC75 has a titanium coating on the diaphragm that makes them a bit different from the Portapro drivers. As far as I know the KSC35 is the uncoated version.   A lot of the sound actually comes from the clip/headband. If you clip KSC75 drivers into a Portapro headband they sound...

4AAs could probably be used as weapons. Be sure to give them plenty of burn-in and as much power as you can provide. Still great headphones despite being over 40 years old.

For the 4AAs, the new drivers were earwrenchingly harsh and tinny. Over time they mellowed out and now they're some of my most transparent headphones. The highs can still be a little grating sometimes but there's a lot of detail and clarity in the sound.   The 4AAAs in their current state...

I also recently got my 4AAAs rebuilt. The sound is much different before burn-in but they're improving little by little as the hour start to rack up. My AAs weren't very nice to listen to until I got them over probably 80 hours.

There are some kinds of shoelaces that are (or can be made to be) hollow on the inside. If you found some of those you could probably use them to sheath the cable.

Konbanwa.

I'm actually down in Oak Creek.

I always thought the 4-X was a dynamic model. That is indeed interesting, I'll ask the rep at Koss about them when I swing by there in the near future. I might have to try tracking a set down.

I think the AAA driver might be wider, but I don't have my set here to measure. I'm almost positive it has smaller magnets than the AA since it weighs quite a bit less. The huge voice coils and magnets in the 4AA are what make them so heavy.   In terms of modern cans I would say they have a...

The 4AAs need a lot of burn in and a powerful amp to sound ideal. That aside, they're two completely different sound signatures. The 4AA goes for detailed transparency while the Portapro has more of an active, bassy sound. It all depends on the kind of tastes a person has. The 4AA is magical...

K141s sound awesome amped. Prepare yourself.
