Customer Reviews

Not just for air travelers and joggers
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.

Excellent portable headphones for the money.
The Sennheiser PX100s are the entry end of Senn's PX line (which includes the open-aire PX100, the closed PX200, and the noise-cancelling PX250). They retail for $39.99.

The PX100s are small, unobstrusive phones. They're suited to portable music players (portable CD and MP3 players), as they are relatively efficient and drive well for the most part. They are small and thin, so you won't look like a complete geek or goofball wearing them in public, and they fold up cleanly and could easily fit in a shirt or pant pocket. They also include a carrying case. The build feels flimsy, but they are actually far more durable than one would imagine. The cord is thin, so beware snagging it too sharply, and short (these are not for use with a home system). They are also extremely comfortable, with a large "sweet spot" and light weight.

Out of the box, the PX100s sound extremely "sweet." They're remarkably soft and smooth sounding, and this will initially sound somewhat disappointing, unless you listen exclusively to jazz. Never fear, however. After about one week of normal use, the highs and lows open and sharpen up, and the headphones become well suited to more aggressive, harsher sounding music (such as metal, hip-hop and hard rock) as well as natural and smooth melodies. Overall, there is a slight emphasis on the low-end; there is pronouced bass without any "bass boost" or EQ needed. However, the highs and mids are never drowned out, so the PX100s never sound muddy. The midrange is strong, and while the highs come in weakest of the three, they still sound better than any other phones I've heard in this price/weight class (the Koss PortaPros, the PX200s, the Bose TriPorts).

It should be noted that the PX100s are open-aire headphones, meaning they offer close to zero isolation. What this means is that they block out very little outside sound, and at high volumes in a quiet area (such as a library) your music will most likely be audible to those in your immediate vicinity. If you MUST have closed phones, the PX200s are the best choice, though it should be noted that they are very finicky in terms of their "sweet spot." It's occassionally hard to get the PX200s in exactly the right spot of ear and can result in disappointing sound, one of the reasons I ended up choosing the PX100s over the PX200s (as the 100s feature a much broader sweet spot on the ear).

I highly recommend the PX100s to those looking for alternatives to the "stock" phones that come with most MP3 and CD players. For those seeking high-quality sound performance on the go, and don't wish to carry monstruous DJ-style headphones (or "sound support systems" as my father refers to them), the PX100s are an excellent choice. They sound great, they don't look bad, and perform well without the need for any external amplification. They might drain the battery a bit more than the stock ear buds, but the difference is negligable and definitely worth it when you hear the difference in sound.

Wow!
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.
