" It;s just good ol knowledge. See the comparison yourself in the pictures. This is a rack that I see lasting years because of its quality. Personally, I love them both, I own several pairs of Bobs and after getting this pair of Toms, I have another on the way! Was scared to buy an expensive headset but I’m glad I did and I’m extra glad it’s wireless! Tal cual aparece en foto, son cómodas y ajustan muy bien. They no longer hurt when I go to bed. :) Though, I suppose you might want to take them off if you are walking on wood or tile floor by a light-sleeper. Super comfortable and look great! Easy to pair with my iPhone, great sound across a range of frequencies, and a nice charging case.
