Excerpt: I was looking for lightweight, great quality headphones with a balanced sound (as in not intentionally boosting certain frequencies). I work on audio professionally, so beats by dre headphones and similar products were not anything I was looking for. I was able to narrow my choices down to the Sennheiser's Momentum over-ear headphones (bluetooth version was not available when comparing) and the KEF M500 on-ear headphones.
Excerpt: I bought these headphones for recording wildlife in the field, and so far I'm very pleased. They give me a clear picture of what's coming in through my Sennheiser short shotgun mic. The sound quality seems excellent whether being used with the recording gear or with my iPod (where the remote volume control comes in handy). These are not noise canceling headphones, they do let in loud outside noises, but for my purposes they are perfect.
Pros: Comfortable, Compact, Great Sound, Lightweight
Excerpt: These headphones are light & small, but have enough heft that they don't feel like toys and they deliver a big sound. This version has the built in mike, but they work like normal headphones when plugged into a device that doesn't require the speaker function. The volume control works nicely on my iPad, but I haven't tried the speaker. The 4 ft cord is too short for my needs. The control buttons are on the mic housing and therefore, near the mouth.
Excerpt: I'm a dj and I really value excellent headphones. The PX 200 is super solid to say the least. The freq range is very nice, doesn't sound flat at all but has really good stereo imaging. The highs are clear and clean and the bass is deep. And what's great is that it does a nice job canceling out some noise in the background (without being "noise canceling"). The build feels very solid. I was surprised how light it feels when wearing and is super comfortable on the ears.
Pros: Comfortable, Compact, Good Bass, Good Value, Great Sound, Lightweight, Stylish
Summary: The headphones provided great sound with clarity at mid and high volume. Bass was a little lacking, but adequate for the price. Build design provides good portability but seems fragile if mishandled.
Pros: Sound quality and clarity. Comfortable fit. Light weight.
Cons: Fragile feel in terms of construction. Lacking bass.
Conclusion: I have bought one in Frankfurt two years ago, and this time I bought this one for my wife in Sonic Electronix, which shipped it fast, I appreciate the fast shipment.. It's really a nice one that has a compact size with folding feature, its sound quality is the best below 100 dollar that I have ever listened. You can't go wrong with Sennheiser PX 200-II, I highly recommend it to people who wants the best sound with less money.
Excerpt: I bought PX 200-II Headphones for everyday commute by train. This headphone meets all my expectations: great sound, deep bass and perfect stereo. For me is important to have it in collapsible form. PX 200-II has reasonable size: not too big, not too small, enough to cover ears and not to hear outside noise.
Pros: Comfortable, Compact Design, Easy To Use, Great Sound Quality
