The Sennheiser PX 100 Headphones use dynamic supra-aural mini headphones and a slim, lightweight design to provide convenience and superior sound to the traveler or outdoor user. Sennheiser's duoful diaphragms with spiral embossing provide high-resolution sound, while the twin damping technology creates crisp, fast bass response, helped by 80ppi polyurethane and special perforated elements. The ear cups can be turned 90 degrees and closed up, then put into a rugged carrying case that can fit into a shirt pocket. The included headband padding helps provide the perfect, snug fit for your head.

5.0 out of 5 stars Not just for air travelers and joggers November 10, 2003
Amazon Verified Purchase
I was looking for phones that would pack plenty of punch without sacrificing any of the qualities of their full-grown, ostentatious siblings. Anyone who's even moderately serious about headphones knows that the smallest improvements come at a price. In the case of these phones, the cost is easily justified. I've compared them with several portables in the $5-10 range along with some full-sized models weighing in at $50-100. Conclusion: these are worthy of being your "front-line," and perhaps only, pair of phones. They're up to the task of distinguishing each of the instruments in a jazz rhythm section or reproducing the spacious quality of an entire string section. The treble is distinct and "alive"; the bass is, if anything, more than I require (and the PX 200's are supposedly the bass-heavy models). Comfort? They feel the same as any $2 pair of portable headphones--until the music begins, at which point "wearability" is not even an issue.

Be forwarned that no 1/4" adapter is included. Apparently Sennheiser wants consumers to view these as strictly low-end phones suitable only for connection to a portable CD player. Nonsense. My only real disappointment thus far is the awkwardness of folding and fitting the headphones back into their hard case. If I can get this down to 60 seconds or under, I'll probably revise my rating upward.

2.0 out of 5 stars Great sound at a cheap price isn't necessarily cheap November 25, 2005
Amazon Verified Purchase
If I were only reviewing the sound quality of these headphones I'd give them 5 stars. If I were only reviewing the comfort of these headphone I'd give them 5 stars. After all, I've bought three sets of them I liked the sound and comfort so much. The problem is, that it was three sets in less than 18 months...

All of them failed in the same way: the right channel just crapped out from a cheap cord design. The first set I chalked it up to me not treating them right. The second set I was a bit angry about but I decided to try the warranty replacement. Unfortunately, I was dumb enough to buy a 3rd pair while waiting on the very slow warranty service, which wound up replacing them with a completely different model of headphone to add insult to the whole process.

Well, yesterday, in spite of my gentlest treatment yet, set #3 crapped out in the right channel after only 4 months. That's it, I'm not wasting any more money on these headphones and I recommend the same to everyone else.

5.0 out of 5 stars Wow! July 23, 2004
Amazon Verified Purchase
I bought these to go with my new iPod, and all I can say is "wow". I can't believe these headphones cost under $50. The folding action is very convenient, and the case that comes with it is top-notch. These sound warm and full, amazing for a lightweight set of headphones. They are the perfect complement for the iPod or any other portable device. Not quite as comfy as my Sony cirumaurals, but they fold up into a neat little case.

4.0 out of 5 stars almost audiophile Quality October 21, 2005
For the money you pay, these are great headphones!!! They art light portable, and by my audiophile standards have passable Sonics. Do not let this throw you off. As a lifetime audiophile, my requirements for sound are very high. Compared to anything I have heard at or near this price range these headphones simply rock. I purchased these for my laptop and also for a future mp3 player. My goals were to find headphones that were not only portable but sounded good as well.

Sonically, on a scale of 1 to 10 here are my ratings .........

Neutrality 8.5

Transparency 7.5

Space & air 8

Micro dynamics 7

Dynamic range 7.5

Base extension 7.5

Base accuracy 8

High Freq extension 7.5

High Freq accuracy 8

Headphone comfort 8.5

Freedom from listener fatigue 9.5

Keep in mind that 10 would represent perfect, so these are very good scores indeed. Most head phones in this price range would reveive scores of under 5. Audio sins here are sins of omission not commission hence the 9.5 score for low listener fatigue.

I hope this helps.

5.0 out of 5 stars The best! August 27, 2004
These are by far the BEST portable headphones on the market today. After spending several days deciding between these and the Portapros, I decided to choose the Sennheisers. I couldn't be any happier. While the Portapros are very good headphones, I thought the bass was a little too overpowering (not to mention it looked a little too goofy for my tastes). The PX100's, on the other hand, have tighter bass and allows me to hear the rest of the song instead of a constant "THUMP THUMP THUMP" through a bass-intensive song.

Granted upon first listening to these, the bass was kind of weak and the entire range sounded very flat. After burning in my headphones over two nights, these have really opened up! I was blown away by what these little things can do! They sound like headphones twice the size and cost. The bass is in my opinion perfect. Even when its hitting hard, I can hear subtle background instruments that i've never heard before. Of course, those of you who like more or less bass can adjust accordingly with equalizers. Personally, I like the Rock setting on my iPod mini.

Senn also included a trick hardshell case that looks like a glasses holder. The headphones fold up like a pair of glasses and fit perfectly inside, with the cord wrapping around the base. The case looks very sturdy and your investment feels very secure once inside. Some reviewers complain about how tricky it is to fold it up. Personally I think if you can't get it right after a few tries, you should probably to back to kindergarden and play with legos some more. Senn even included instructions on the backside of the case too.

Keep in mind that these are open-air headphones, so sounds will come in and your music will be heard by those around you.
