Sennheiser PX 100

Sold Elsewhere
MSRP $69.95
This product is no longer available at HeadRoom.

DISCONTINUED. Not only does it sound great, the Sennheiser PX100 is stylish, durable, and folds up to fit in a space no larger than a pair of glasses. Truly a great general purpose headphone, it will satisfy kids doing homework, dads listening to the ball game on the back porch, and even the discriminating audiophile for their casual headphone needs. These ear-pad open back cans won't isolate you from outside noise but similar audio performance in a sealed is available with the Sennheiser PX200.

  • Hard-Sided Flip-Up Travel Case


The Sennheiser PX100 is simply the perfect portable headphone to upgrade the so-called headphones or earbuds that originally came with your Mp3, iPod, iPhone, DiscMan, or other portable player device. An open-backed and highly efficient design, these small, lightweight headphones deliver amazingly crisp, punchy sound with a strong bass response even when used straight out of a portable audio source. The open-backed PX100 earcups provide no ambient noise-blocking, but allow the listener to remain aware of their surroundings--important if listening around busy city traffic! And if coming up with a headphone that sounds slightly better than the previous winner in this category (the Koss PortaPro) wasn't quite enough, the PX100 is also a bit better looking, more durable, and has the nifty ability to fold up tiny like a pair of sunglasses. This might be the best "open" headphone for under $50 bucks, and a perfect choice for great listening on the go, at the gym, or directly from your laptop computer and/or iPod. Plus the PX100 plug has now been made iPhone-compatible for all Apple fashionistas!

The PX100 achieves a comfortable fit using a super-lightweight metal headband with two foam headband pads resting on either side of the top of your head. The small supra-aural earpads are made of a fairly soft mesh-type material. The headband folds at two sturdy hinge points located just outside the pads. The earpads swivel 90 degrees and tiny detents interlock the side band pieces to make a conveniently small package that, when folded, easily stores in your shirt pocket, bookbag or backpack. The headphone also comes with a protective hard-sided plastic 'sunglass-style' carrying case that's very secure and basically crush-proof, but rather awkward to deal with. The PX100's Y-cord attaches at each earpad, is about 4' feet long and terminates to an 1/8" (3.5mm) plug. Replacement earpads are about $5 bucks a pair and available directly through the Sennheiser website. The free 2-year manufacturers warranty remains standard with all Sennheiser Electronics headphones when bought ONLY through an authorized dealer like HeadRoom!

Recommend Product: Yes
Pros: Comfortable, Affordable, Compact, Light, Great Sound
Cons: Open Style doesn't provide isolation, can be heard by others, seem to be delicate

I love the way these sound.
I own several different headphones and these have become my basic benchmark for sound comparison.
I will always do an "A-B" comparison of the headphones I am thinking about buying with my PX100s.
I have worried that they may be delicate, but have been using them for years and have never given a bit of problem.

No man's land
Posted by aramg83 from New York, NY on 2010-01-18

Recommend Product: No
Pros: Excellent Sound, comfortable
Cons: Lack durability, awkward build

For the price, these are the best sounding headphones I have used. Super clean mid and high and even decent at low range.

I purchased this pair a couple years ago and unlike my Grado's, these have something wrong with them as of a month ago; when I listen to music, I cannot hear vocals.

My biggest gripe, as my title suggests, is that these are neither a home, mobile nor studio pair of headphones. They are too small and weak to be a good home or studio headphone and the lack of a seal prevents them from being an mp3 player accessory.

Go for the 200's which have some form of seal so you can wear them out and about.

Budget Performer
Posted by BeatLover from San Francisco, CA on 2010-01-17

Recommend Product: Yes
Pros: Good Value, Easy to Drive, Hard Case
Cons: sound on the "dry" side

The Sennheiser PX100 is a great budget set of headphones. Their sound is quite balanced and accurate for the price range and their styling is unlikely to draw any attention on the street or subway, an advantage that some audiophile headphones do not share. The hard case is a major asset for the budget crowd, as they hold up well in a backpack, something which the baby Grados do less well. For the price, I can't think of anything better.
