Will be great for work. ) Amazing sound, great bass, treble, vocals sounded great (I personally liked setting 3). FITS LOOSE HAVE TO INSTALL UPSIDE DOWN TO MAKE IT WORK LIKE I WANT Perfectas. I did have a slight issue with my fan and I contacted custom service to see if it was common. I have been looking for a slide type shoe to replace the Rose slide that is no longer made. The memory foam is impressive. While the memory foam compresses, they will slowly push out of your ear as the memory foam takes shape. I can get specially fitted for running shoes, and they end up hurting so bad I take them off and limp home. A nice improvement would be a switch to turn off the lights or perhaps limit them to a couple of LED segments so it isnt so bright.
