Neat layout. I can actually feel the air pressure as I put on the headphones. Extremely high quality and very durable. I am still on vacation and the tops of my feet have had open wounds from these for 6 days now even though I haven?t worn them since! The fit was good, however the plastic strap rubbed on my inner arch in a very uncomfortable way so I had to return. Probably one of my better exercise purchases. Love that the HQs is based in the U. I found the sound consistently clear & crisp in various types of music. I used the tool that was provided with the set and placed some cloth to protect the roof from accidental scratching. It all turned out to be quick and easy to install.
