When I put them on, they almost immediately cut the circulation off to the front of my feet. the adjustable springs help add or remove tension based on the weight of your mic. I had my last deathadder for maybe 7-8 years, Im not really sure. Sound Bleed - Weird that it muffles exterior sounds so well, yet even at very low settings these seem to be clearly audible to people around you. They fit me fine but only just, so you may want to round your size up rather than down. Without a doubt this is the Best Bluetooth Headset I have owned and I have owned plenty. Just love it. Also, in repacking, product documentation was not included with the poles and therefore, it remains unclear to me what the additional, included extra materials are used for. And my daughter is also so thrilled that this backpack has a vented show compartment so that she can keep her tennis shoes from touching the rest of her items. But my toes go past the bottom of shoe and is a tight fit (which is raised up with extra cushioning - more cushioning than my old slippers) and the slipper doesnt come up high enough on my foot for my taste.
