The Koss Porta-exceeded my expectations by far.
- He is a perfect, all frequencies balanced surround sound again, I know only by expensive closed headphones.
- It is lightweight and does not press.
- He does not slip during movement, making it ideal for athletes.
- It fits in every backpack and fanny pack each.
- The metal ring is durable and does not break (as ichs often experienced with other models).
- The folding mechanism is simply awesome. Quite differently than expected, it protects the ear pads during transport.
I'd the Koss Porta-because of its great sound buy immediately, but as already mentioned: he just does not break !!
