Amazon has the PortaPro Headphones with Case for $35.67. Koss' PortaPro headphones are one of the best and headphones offered.

Design

The PortaPro headphones are very comfortable, multi-pivoting ear plates with adjustable headband, and collapsible for portability on the go. The design of this headphone is very retro and you may often find people glancing over when walking down the street.

These headphones sit on your ears instead of over your ears. The build quality is very sturdy and the sound quality is great. Many audiophiles recommend it.

These headphones are not too bass-y, great for anyone who don't enjoy too much bass. We highly recommend these for anyone who are looking for great headphone around $25-$50.

Alternatives

If you want headphones for a lower price we recommend the Sennheiser HD201. These headphones are usually lower priced, have a little more bass, and a 6 feet cord.

Amazon also has the Sennheiser PX 100-II is another alternative (usually more expensive) than the Koss' PortaPros. These headphones' sound quality is comparable to the PortaPros, collapsible also, and lower profile.
