So I worked out with NO music. My future video production would benefit a lot from this mic! We had gotten a auxiliary cord a few years ago that was wrapped with braided nylon and it has proved to be much more durable than previous cords, hence the search for tougher earbuds. I can not pinpoint the irritant, and I should mention I have the skin of a baby?ridiculously sensitive (you thought I was going to say luciously soft and seemingly hairless)?when it comes to body wash, detergent, lotion, etc. Does not bunch up and fits really nicely. Sweeet sweet bass3. The audiophile who had the opportunity to try the Momentum?s told me there wasn?t anything special about them and he compared the sound quality to the E8?s. To be fair theres not a large number of mechanical wireless keyboards to begin with, and most of those are also still using ABS keycaps, so you may be stuck with this regardless (when the Keychron K8 eventually comes out, its keycaps will be ABS but are at least OEM profile and can be swapped out). I suffer from plantar fasciitis and have no trouble wearing these. Not great, not terrible.
