Focal Listen, closed back over ear headphones. Folding design with durable headband and removable cable with inline mic (no volume control). This is an easy to power (great match with a phone or computer) very clear, balanced sounding headphone with excellent extension in the treble & solid deep bass response - not boosted, but no bass lightweight.
Great sound quality and clarity at the $300 price range. If you have a large head these will feel tight.
