Koss Portapro Appreciation Thread - Page 3

Good one dude! So the seller's making... like .... $2??? LOL!

[Edit] Admittedly, I was just trying to joke around with this post. Hope Krames isn't offended by it.

Which Radio Shack pad mod??

Get the regular-sized foam pads from The Source (Radio Shack) and stretch them to fit the Sportapros. The stretching will cause the contact patch to create a bowl, since the outside edge of the Sportapro driver is too big for them. They are still comfy and I have noticed a significant difference in the sound quality.

I must comment

My first hi-fi aware purchase was the portapro, and I've been smiling ever since. I've never encountered such great sound(stage) at this price range. Yes, I've since moved to Grado-60, and now the portapro sounds a little muddy in comparison. But as others have mentioned, that soundstage still isn't beat. IMO, portapros are perfect for decently ripped (around 198) MP3 tracks. You've lost some detail, but the portas usually don't notice anyway. And yet you still get that great warm sound. Just a great can.

On another note, I've worn them so much that I may have damaged them. One of the pads popped off and I have to put it back on periodically. Also there is a slight rattle on some bass notes that wasn't there before. Anyone else experience this?

These were also my first set of "real" headphones (note the nick, heh). I bought them about four years ago when the Fry's stores decided to markdown their stock of Koss phones. They were going for $19.99 and I decided to buy it on a whim. Coming from Sony street-styles and generic headphones, these were such a step up! In fact, I really began to enjoy my music more because of these headphones.

A couple weeks later, I went to Fry's again and they had put all their Koss stock in a cart. The Portapros were marked down to $9.99 and there was an open-box pair of Sportapros that was priced at $1.99! I went ahead and picked up the Sportapros and a couple of spare Portapros.

I'm still on my first set of Portapros (until the HF-1's are open for sale again), and just recently, the foam pads began to come apart. The Sportapros are my daily use cans with my iPod since I got them.

amped koss pp is even better
so impressive

Often it's usually a small piece of hair that made its way onto the driver's surface. Remove the pad, pop the cover plate off and blow out anything that may be there. If you still get the rattle, then ........... I may have solved the mystery. I have some beat to hell KSC35's. Worn in is an understatement. The drivers were actually hitting the cover plate on strong bass notes causing some vibration sounds. I took a sharp exacto knife and trimmed the inside plastic to fix the problem. I took pictures and everything but I'm just too damn busy to post them up. Maybe in a month or so I'll make a thread showing my mod.

an update on my Porta Pro, after passing the 48 hours burn-in mark.

impact! they finally have some kick. the highs have really come around, which is great. it helps to give it a better balance. the bass got a tiny bit more refined, but still feels a little "large". the mids still sound more recessed than I'd like(which results in a lacking performance in deeper male vocals I find), but I'm really happy with the Porta Pro now.

almost everyone with a pair complains about losing a few hairs, but seriously - use a strip of tape to hold the already adjusted size in place. it might not be effective if you fold yours up to put inside the travel bag, but I just have it around my neck anyway.

I think I'll pick up some extra pads and make the holes in the middle.

PortaPro Mods?

Fewtch, I hear you talking about these mods to your PortaPro's, What are they? I hear you talking about the earpads and a 75ohm mod. Could you please tell me exactly how to do these mods? I have some PortaPro's coming via UPS tomorrow,"which should have been here Friday"!darn-it! Anyhow I was recommended to these cans as they suppose to work well with the PA2v2 which I just bought and received this Wed. the amp works "o.k." with my Shure E2c's but as you stated I guess the PortaPro's really come alive with this amp. - Thanks - Sushi

Sorry, I didn't read the 2nd page of this thread, I was asking a question that was kinda already answered, as far as the earpad mod goes I guess you put a 1/4 in. hole in the center right? Now someone has to explain the 75ohm. mod. Thanks - Sushi

75 Ohm adapter

Thanks Fewtch, on the advice - where do I get an 75ohm adapter? - Sushi

Just received PortaPro's!

As I'm writing this I am listening to the PortaPro's with my PA2v2, and I have to say they go nicely together which Gary at Electric Avenues said they would - Thanks Gary. Well I have to say the PP's are bass heavy but with a little adjusting with the equalizer on my DAP I am able to pull some of that bass out, while still being able to keep the mid's and highs comfortable. I'm sure with a little burn in time they might even sound better "so I've read", overall I'm pretty impressed for the price they are definately worth it. I'm sure I'll enjoy playing with these for awhile. I can definately see this is going to be a long "and expensive" road of a few different amps and phones, but what the heck as long as your having fun right!
