Very comfy gives nice and peaceful sleeping. The straps are an adjustable buckle on the top and the neutral color goes well with jeans for summer wear. These do not work for me.

Ive also used Anker bluetooth headphones, BLKpods, official Airpods, Powerbeats3, 2, etc. 5 and the 9. Big but nice, i would recommend it for ppl with big cheeks, yet seller wasn’t cooperative as the golden logo Gucci fall off and wanted to buy the logo only but they didn’t listen i would give the seller 0 as a reviw
