But then again, all weights should be treated with caution, and at this price, this is exactly what I need for my family of four boys to get them introduced to weight training without the expense of joining a gym. Dont get me wrong, I love the headphones. The memory foam is great! My Granny whos 94 loves them. Very soft, comfortable, cushy, flexible. The right shoe is fine but the heel strap is too loose on the left. I have used at least seven brands of clothes moth traps available here on Amazon. Luckily it recharges quickly. Installed on the other side of the room it doesn’t jar. There was clearly no contest between the two headphones in terms of vocals or detail retrieval, but the Razer wasnt a bad headphone by any means.
