The on off button on my Z623s is going bad, which is weird because its always on and I couldnt have wore out the button from use. I can just be watching videos and suddenly my audio starts crackling and goes off. It took me a little bit to figure out what was going on, but if I touch the off/on button then the sound starts playing again. Just touching that button the sound will crackle, get distorted, or go out. How can this button be so weak that it gets faulty even when you never use it? But anyway thats why Im here looking for comparisons because they are a great set of speakers. The Logitech Z560s RGB speakers are a joke. Hated them and gave them away. If the Z625s are as good as the Z623s, Id definitely buy them especially when I can put the optical audio to use.
