I use these in my studio. I have about a dozen of them, some for several years and they're still going strong. They have cupped ear, open back, come with a 9' 8" straight cord and a plug and play adapter -mini to standard- "These will not slip off your ears and they've never made me sweat". I hope this helps.

Here's the pertinent info and here's the link where you can buy them: http://www.amazon.com/JVC-HAG101-Headphones-Discontinued-Manufacturer/dp/B00008DHSN/ref=sr_1_2?ie=UTF8&qid=1455762284&sr=8-2&keywords=jvc+ha-g101+headphones
