Design not for everyone
Retro design with style like from a sci-fi movie. These are KOS PortaPro headphones, and they are on our best headphones under 50$ list.
Headband is made of metal, one solid piece. Cups are foldable, so they are easy to carry. On each side of cup, you can find a switch which will allow you to adjust how firm or loose they are.
Cord is about 1.2 meters in lenght. At the and, you have standard 3.5mm headphone jack. Not in 90 degree to mention.
Sound is very good, as it has most of positive reviews. Still, main disadvatage could be a lack of microphone.
If you can stand without mic, a 4.5 star out of 5 star rating on Amazon could convince you to get one of these.
