They do run a little tight but not to the point where theyre uncomfortable. Here are some cons that Ive noticed with it, Ive also waited 3 months to write this review after purchase, the mouse at times feels a little slippery. For the IE80S I needed to buy the biggest size as they have large drivers for earphones. It actually works! Alle 30 - 45 Sekunden bricht der Sound ein. The best feature is its battery life. The keyboard can pretty much be whatever bundle of colors you want it to be thanks to the Synapse program its controlled by, and even though the mouse and mousepad only light up a single color, they still compliment the keyboard very well. They are far better looking on the foot than in photos, and incredibly comfortable. This replaced an older Sony product that I have had for years. Im very satisfied.
