Ordered size 6, they were too small. Mid and mid-low range was good, but the treble was very weak. I like mine loose, they feel Freer on your feet and if you want to lock them down, put the ankle straps on. My third comment is that you cant change the base word to wake the device. If noise-isolation is not a big issue, seriously consider the Sony DR-EX12IP headphones. So not only did I have to take time to sanitize and clean makeup off a soft surface but then had to search for the directions and call Amazon to have a tech support help me. I only use the buds to skip tracks, pause and take calls, anything else, I resort to doing on my smartphone, for fear of accidentally triggering the virtual assistant. Dont believe the other reviews that say the contrary. The lcd display shows you exactly the power level of the case. The arch strap is kind of short and I had nothing left for adjustment.
