The headphones worked great for about 2 weeks until my son said the sound quality started to make a crackling sound whenever sound was produced. Ok so I wont say these are the greatest headphones of all time but for the price. I love these flip flops and have tried others, but keep coming back to these. -If youre looking for immersive Theater quality, room filling sound that is clear and loud without feeling loud (hard to explain). They look fantastic, and the CROCs insole is still SOLID. I listen to audiobooks while cooking, dusting, etc. Had a great experience with customer service and would highly recommend these bands to anyone looking to include them in their training. This does mean that the straps ARE adjustable by moving the buckle to different holes and the whole thing works ok and is secure, it?s just tricky to get them hooked properly. One interesting thing to note: these sandals are highly uncomfortable when sitting on the ground cross legged because the plastic buckle digs into the foot. The sound quality is also poor.
