First impressions of the 7..................damn do these things have bass. I had to turn off the loudness switch on my Kenwood vintage amp.
For what I wanted - a low profile portable solution for outdoor activities that isolate really well with great bass - they NAILED it. I could see running in these easily as the clamp is nice and strong and they do NOT move a bit on my head.
I'm burning them in at the moment overnight for the next few days just to see if the very deep bass will mellow out some. These fit like a glove, ear pads are great and are great looking. They replace the M-100 and for that they are already quite an improvement.
More to come gents.
