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: When my PortaPros got dropped a few times too many I looked for a replacement. I narrowed the field to the PX 100 II and another pair of PortaPros because I need to have open ear headphones while using the computer. I should have just gotten another pair of PortaPros because the nicer definition on the high end does not make up for the uncomfortably large size. I am not a small person (6' 220lbs) and I never thought of my head as particularly small.
Pros: Clever packaging design, Durable, Nice definition in highs
Cons: Designed for giants, Poor Value, Uncomfortable
Excerpt: You get great sound value for a decent price. Surprisingly comfortable too, especially with the cord attached only to the left side of the headphones, resting the cord on your left side rather than in front of you with the traditional Y-cord. Stay away from it if you need noise isolation...
Summary: These are one of the best open design headphones in this price range. They are very clear and don't leak as much as I thought they would. They are pretty inexpensive and I love the single sided wire. They are very comfortable so you can have them on for hours. The best thing about this model is you can fold them and stuff them in your bag or pockets. These are one of my best purchases, but of course there are always better ones so I upgraded!
Pros: Sound quality, price, single wire, comfortable, portability.
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: This is my 4th set of headphones/earbuds. The previous ones either fell out, made to much noise from the wrapped line or hurt my ears after 30 minutes. I purchased all from Best Buy due to their great service & return policy. I have used these Sennheiser folding headphones almost daily for 3 months. I like the ability to hear things around me while walking, riding the bus or ordering coffee, but still having great sounds. I can't give them 5 stars for durability, yet.
Pros: Great sound and small profile when folded & stored.
Cons: I lost the storage bag, but found a comparable one from another product to use.
