I have used the Koss PortaPro, and it's variants, for more than 30 years. But, as small as it is, it doesn't fold flat for shirt-pocket carrying. And it's open-back, so there's no sound isolation.   I'm looking for a closed-back alternative, with bass response at least as good as the PortaPro...

I have ordered of biosciencegeek cMoy headphone amplifier, and am looking for an 18 to 24 volt ac adapter for it, preferably one I can find locally, such as at Radio Shack. Any recommendations?

I decided to buy a biosciencegeek cmoy headphone amp on eBay, and was saddened to find that his site is completely gone! What happened? And is there any way to buy his amplifiers now? I have a JDS Cmoybb v2.03 that sits on my nightstand, & I listen to it almost every day. I need another amp...

I find that I tend to poke around in this forum a lot when I'm not satisfied with the sound I'm getting from my cans. Not so much when I am. A couple of months ago I bought a pair of Sennheiser HD435s. Now I own some great expensive cans from all the "usual suspects'...Sennheiser, Grado...

I'm considering a new pair of headphones, primarily to listen to portable devices...like my Archos Gmini 402, Eton E5 shortwave/am/fm stereo, internet radio on a Dell Axim x51v, and XM Satellite radio. I've been in radio and pro audio for about 30 years, and have always preferred a crisp...

I remember seeing these 'phones back in the Quadraphonic days of the early 70s. I was a BIG Pro4AA fan then, and, knowing Koss' fondness for using the same drivers in several models at a time, I assumed tha the K 2+2 was just a "gussied up" set of Pro4AAs with two drivers in each earcup (it...

I admit it. I just bought a pair of headphones...something I have absolutely no need for. In fact, I have far too many of them already. I haven't bought a pair in several months. What got me interested was the buzz over the JVC HA-D990 'phones at E-Tronics for 16.99. Unfortunately, I missed...

I just got my first XM Satellite radio, the new Delphi "Sky-Fi", plus the home adapter kit. Since I'm legally blind, I'm less interested in the car adapter, although I probably will eventually buy it. My next purchase will no-doubt be the "boombox adapter" coming out soon. First impressions...

I'm a fan of surround sound. I was WAY into it in the 70s. I love it for movies, occasionally use it when producing for fm radio (matrix surround), and love it's POTENTIAL for music. But as much as I love surround sound (enough that I never threw out or traded my SQ matrix gear from the...

I'm a radio lover. I collect radios like others collect, er, headphones (ok, I collect them too!) After 30 years behind the microphone, I KNOW that fm radio has far more fidelity potential than the average audiophile gives it credit for. In fact, before the adoption of the noisy Zenith system...

I live in a difficult area for fm reception. First of all, I'm in a rural community, so I'm in the "deep fringe" of most fm signals. Except for one! There's a full-power (100,000 watt) fm here in my county, whose tower is only about 8 miles from my house. The signal they put into my area is so...

I predicted a year ago that both SACD AND DVD-A would fail in the marketplace because, to the average consumer, they are solutions in search of a problem. To most people "CD Quality" is spectacular, and doesn't need improving. I KNOW all the audiophile arguments. But I think audiophiles...

Well I just got my Sennheiser M@H40 (the new version of the classic HD-40), and I've got to say that I don't really recommend them. Despite their "low impedance, easy to drive" claim, I find them extremely hard to drive! Portable audio devices simply don't have enough "oomph" to get them really...

I just noticed that Koss has REMOVED the KSC-50 from their website. But they still feature the KSC-35. Perhaps they've listened to those of us who have screamed that the "50" is a GIANT step backward (because the looser fit sacrifices bass response, comfort, AND security...as they simply don't...

I'm an American who just wants to "hug a Brit" today. Since that's not possible (in my rural North Carolina neighborhood), I'd just like to say THANKS to any Brits here. How wonderful in these frightening times to know that we are not alone. The friendship of your nation will never be forgotten...

There's a SUPERB article in the October Sound and Vision written by David Ranada about why NOBODY has yet proven not only that either DVD-Audio or SACD are superior to one another, but that EITHER is (AUDIBLY) superior to regular 16 bit 44.1khz. In the article, they cite tests which PROVE that...

Well I've finally given up on trying to find a portable cd player with a decent fm tuner (the Panasonic unit I ordered from J&R DID NOT!) So I've turned my attention to my other interest lately...mp3 cd players. You may have read what I wrote about the portable unit from RCA that I bought...

My quest for a portable cd with SENSITIVE fm/am tuner continues. I want one that receives distant fm signals at least as well as my radio-only "Walkman" type portables from Sony, Radio Shack, and Sangean. Is that too much to ask? Has anyone here heard the Panasonic SL-SW650K "Shockwave"...

Well, I was at Radio Shack tonight. I had stopped by to check out the portable cd/am/fm stereo unit that's on sale for 49.95 (usually 79.95), when I spotted the RCA RP-2410 mp3/cd player on sale for 119.95 (it WAS 169.95). Since I've had a VERY good month with my production business, and will...
