Electronics Sennheiser PX 100 Collapsible Headphones

Rating: - Great open-ear headphones!
I had the Sennheiser PX 200s in high school- When blocking sound was key. Beginning in college, I was walking around a lot more. Crossing streets, running into acquaintances, and not sacrificing sound quality. The PX 200 and PX 100 are similar in sound quality when listening in a quiet room (Libraries), and luckily the music needs to be especially loud in order to leak out the side (A problem I have with other students wearing earbuds is how incredibly annoying it is to hear JUG-JUG-JUG-JUGGA-JUGGA-JUG-JUG over their earbuds).

These headphones are incredibly lightweight, collapsable and perfectly foldable, work with the iPhone classic (Not that anyone has one of those anymore. Man I'm old), and don't sacrifice quality.

The only bad thing with them is how OPEN they are. I'd say 5-15% noise reduction with no music. This is wonderful for when you are crossing a busy street or get asked a question on the bus, but it cannot drown out sound. At all. Like, not at all. In loud situations (Public bus) the only way to lose the crowd is to turn up the volume and that's bad.

Wonderful lightweight open collapsable headphones- Perfect for those seeking a quiet respite in the library or on your morning walk/jog. Not recommended for angry teenagers who need to drown out their parents with Linkin Park.

Rating: - Great headphones
These sound great and they are comfortable. I have purchased 4 of them over the last two years. For work and the family. Never had a problem - any problem. Though to purchase replacement ear pads (part number 89331), I had to go to Ebay and pay 7.90 or so for a bag of two. Sennheiser does not ship replacement ear pads to the USA. Oh well. These headphones got great reviews in PCMag and elsewhere. So, I like them.

Rating: - Great Value But Limited Longevity
As many others have said, these headphones have very good sound quality, particularly for the price.

My main complaint is with the wire connections. After a year or so of owning these headphones the plastic had started to tear (with normal usage). Thanks to some timely repairs I managed to get another year of use but just recently the connection to the right headphone frayed through completely. So that's that. While the headphones worked I really enjoyed them, but based on my experience, don't expect the PX100 to last more than a few years.

Rating: - Very solid for $30
This headphones won't blow you away with their sound quality, but in my experience, they're among the best you can get for less than $30.

Once you figure out the Rubik's Cube that is the fold away system, they'll grown on you as their compact size and thoughtful design soon earn their mild price tag. If you're hard on your headphones, and tend to go through them quickly, I'd go for these.
