Theyre excellent for larger heads, but theyre great for small heads like mine, too. SHOULD HAVE BOUGHT THESE EARLIER. Update: after a few months of usage the whole thing dies, no lights. So much fun! Some of the attachments "work" but not really well. Now that it plays nicely with our PA, Im happy with the clear uncompressed sound, especially with really good in-ear monitors. My only complaint would be is that its heavy. I use the headset for work/personal use and it will force me to buy a new headset in the interim, or do something like that to bridge me through until I get it back. I had the Bose QC 20, which are also really great, and was planning on going from an iPhone 6 to a X. I had these delivered at the start of the week and have been using them constantly during the day for 4 days now.
