Oddly, it took several reboots on my MacBook Pro for the Razer Synapse software to work correctly and it still sometimes asks you to connect a Razer device when you open the Synapse app. I don?t mean you should be a doormat but genuinely wanting to find the best outcome for all parties involved is just right. The Sennheiser Hd 600s is lacking in this category. The sound profile on these is perfect for gaming and I think anyone would be happy with them for music listening too. The bottom cover is still attached but also in the process of stretching. I would have given it 5 stars, but there is a smudge on the front and some chipping on one edge, however, touch up paint fixed it where its not really noticeable unless youre looking for it. Installation was as simple as remove the old kickstand and replace it with this kickstand. Im very disappointed in Logitech for not including a wrist rest with this keyboard that covers the entire length of the keyboard. I use these in the gym, and unfortunately my ears do pick up the sound of the weights and barbells clanging. But alas not!
