Sound quality is very good as is the comfort.
J. Shouse
They're very balanced - treble and bass and mid range are clear at low and high volume.
The audio quality of the PX 100-II is better than these more expensive headphones.

Not sure why this product is listed under multiple names. Too bad since not all the reviews are together.

There is a lot of controversy over whether the new version (px100-II) or the old version (px100) of these phones sound better. I owned the old version for many years until they finally broke. I ordered the new pair to replace them. For me, there is no question the new version sound MUCH better than the old. They are more dynamic, detailed and have much better, more defined bass. Instrumental separation is vastly improved. Overall a very natural and balanced sound, but detailed and dynamic at the same time. In fact, I think they are quite an astonishing bargain at the price.

They make the old px100 sound too smoothed over and polite. The old phones also had a very natural sound, but they took the edge off everything. I think the controversy stems from the musical source people are listening too. The new headphones are more revealing and detailed than the old model. They make good recordings sound better, but they make it easier to hear the flaws of bad recordings and make them sound worse. Some people may finally be hearing the problems with downloaded (low bit rate) mp3's that were smoothed over by the old px100. Bad recordings and low bit rate mp3's might sound better smoothed over by the more recessed, laid back sound of the original phones. But listen to the new phones with a high quality recording on a CD (or a song ripped with a lossless format) and they are amazing for the price. Also, do not forget to break them in. Like many headphones and speakers, it takes 30 hours or so to break in the drivers which can be overly stiff when new.

Throughout this review, I'll explain why I appreciate this headphone to the extent I do, and how it competes with more exquisite offerings from the same manufacturer. But I'll also be comparing to a few other models from different manufacturers as well. Not to mention, with me finally getting my hands on an original PX100, I can finally determine for myself whether or not the PX100-II is actually a worthy successor, or inferior as some suggest. Of course, even that is based on one's own opinion.

So, I want to mention one thing real quick before I get started about the headphone itself. The HD598, HD600, and HD650 are some of my very favorite headphones. A few months ago, I was lucky enough to have all three on my desk at the same time. Comparisons raged back and forth, but ultimately, I came to choose the HD598 over both the HD600 and HD650, mostly based on value. Although I really liked the slightly fuller and refined sound of the HD600 and HD650, I still chose the HD598 mainly due to it sounding 90%+ exactly the same but for half the price; as well as having a more airy and spacious sound. So out went the HD600 and HD650. But, the HD598 wasn't safe for long. I soon found even it started becoming uncomfortable after a few hours of use, so I decided to try the PX100-II due to how much lighter it was on paper. To my amazement, not only did the PX100-II surpass the 90%+ matched sound quality test with flying colors, but it's signature simply outclassed the HD598 in most cases. Don't ask me the technicalities of that conclusion, but the PX100-II just sounded more balanced and engaging to me. Truer to the ear, at least based on my preference. Simply said, it just sounded better.

I had the Px 100s for about 5 years and loved them. I used them every day. The wire finally broke and when I went to replace them found they'd updated them to this PX 100II. I'm far from an audiophile, just a regular person who loves music. But I have to disagree with the person who said these were inferior to the PX100s. I find them the listening experience to be very similar. In fact, my husband still has his PX 100s and I listened to the same song with both and I'd be really hard pressed to tell the difference. I do like the one-sided cord. And they are much sturdier than my old model. It could be that I just need to break them in, but they seem heavier on my ears (I think the ear foam is more substantial) and more rigid. I'm not sure I like the feel as well as my old Sennheisers. It may just be a matter of getting used to them. They come with a nice sturdy carry bag. I think it's is an improvement over the hard plastic case of the old model. It was always a bit of a puzzle to get them in the hard case and half the time I didn't try. So all in all, I recommend the PX 100-IIs as fantastic earphones for the price.

For me, these headphones sound at least as good as the older model, and they look better. I don't know whether the thicker headband makes them more long lasting, but it contributes anyway to the improved appearance.

Some reviewers here say the older model sounds better. I think that just shows how individual our hearing is. I would not say those people are wrong.

I'd like to know why this listing does not specify the make and model. I puzzled over this listing a long while before buying. I'm now convinced the thing I got is a genuine Sennheiser PX100 II, but I was wasn't fully certain about that until the item arrived.

Regarding a certain strong competitor in this category: I don't know how good the Koss PortaPro sound, and I'll never find out because to me they look absurd. There you have one of my biases, how the headphones look.

In my opinion, the sound of these headphones, and of the older PX100 model, is astonishingly good considering their light weight and low cost. I heartily recommend them.
