Summary: I bought the first model of these headphones for my H.S. and college aged kids a few years ago to replace the earbuds that came w/ their MP3 players. We were very impressed. Now, I have gotten the newest model of these headphones and I`m very pleased with the fit, comfort and mainly the great sound. I like the open-design, and single cord.
Pros: Comfortable, Good Bass, Good Value, Great Sound, Lightweight
Summary: I just picked up a pair of PX100-ii today. I've been missing the PX100, and I've been curious how the sequel improves on the first one. First impressions (comparison to original from memory)...
Sound: the bass is a tiny bit louder and kicks harder, mids a little more laid back but a bit cleaner, highs the same. Running a frequency sweep, I think the highs on the ii are maybe a bit less wobbly. On fast bass heavy songs, the bass tends to bleed a bit into the mids.
Pros: ultralight and comfortable, single sided cord
Cons: no hard case, more expensve than its predecessor
Summary: for me they r the best portable headphones i have ever bought in my life. well i am only 19 now. i hv done a hd515 review too.there u can see where rate these headphones.these r the fun headphones.. with everything almost right.. well i consider this as portable audiophile headphones.(imho ). well u can go to this link for the detailed review by katun. he did a very good review.well u will find me there too.
Summary: The PX 100s are certainly a supra-aural can to be reckoned with. If they were about $20 cheaper, they'd beat all of the Koss offerings for best value in portable headphones.
The bass: thick and meaty without being muddy. Works as well with Jay-Z as it does for the LSO. Even though it is solid, it never feels congested. There's enough space to make it feel natural.
Mids: Just slightly behind the bass. Still nice and rich with good clarity.
Summary: There's not a whole lot I can say about these. I think they are an excellent compact headphone to have in a bag on the go, they are affordable, sound good with everything, and are a definite step up from the crummy earphones that come with most cell phones and iPods.
Pros: Fun bass, compact, surprising soundstage, jack is phone case-friendly, non-fatiguing, good for all genres, discreet
Cons: a little plebeian looking, upper mids and treble are a little veiled, some rattling with super low frequencies, no noise isolation
Summary: This will be a very brief comparison review with the PX100, my review of which can be found here: http://www.head-fi.org/products/sennheiser-px-100-collapsible-headphones/reviews/8181
This is the most striking difference between the PX100 and PX100ii, with the latter being the far better off. The PX100 has aged noticeably, and the updated version really does look far nicer.
Pros: Sounds fantastic, Very comfortable, Sturdy build quality, Attractive aesthetic design, Super portable, Serviceable
Cons: Doesn't isolate, A hair less comfortable than before
