Input:
These are the best affordable headphones around! I've purchased a pair for the office, a pair for my house, and given pairs as gifts. I even talked my boss into ordering these for our department.

There are definitely headphones that sound better, but none that combine the sound quality, comfort, and (low) weight of the Porta Pro. They are also fairly durable, esp. if one takes reasonable precautions (like using a carrying bag). On-ear headphones will never seal as completely as full-size headphones, but these do block out most external sound and "bleed" very little internal sound.

There are multiple colors of Porta Pro readily available online : all-black, all-red, all-white, etc. I've also seen a version with a braided fabric cord (rather than the usual rubber cord), which is less likely to tangle. Check for those first, esp. if the retro styling of the traditional model isn't your thing.
