Pros: On ear, adjustable, serviceable and good sound.
I have used these headphones for 30 years and have had a really good experience with them. The overall sound is tight and fairly accurate. I say fairly, because being on ear rather than over the ear doesn't completely contain the lower frequencies within the listening experience. Other than that, they have been good value and easy to repair, given the flimsy plastic headband and the plastic pieces on the spring wire. For what I paid for them new, they don't owe me a thing and still work well.
