I?ll let it rest for a couple of days to see if it dissipates, but it almost burns my nose (and probably gives me cancer, LOL) Aside from a few embarrassing typos (which made me wonder if I had been sent a working copy), I was really satisfied at the end of my read. futile. If you want the fancy effects that are supposed to come with a 150$ keyboard, you will be disappointed. The bar was actually covered in a light coating of machine oil, presumably leftover from the manufacturing process. It also has a neat logo/emblem, although youll hardly see it. The cushioning on the bottom is too notch and stability is amazing. Im on my feet all day at work, so I look forward to wearing these. Overall looks nice, feels comfy, but not suitable for long walks as it becomes uncomfortable. 3 months I been using this buds, had to pair them every month.
