My only reason for 4 stars is, they had some dirt on them at the toe and heel; so Im assuming these were a try on fail with return or Prime wardrobe fail and return. Cable started coming out of the right bud. No thick manuals or anything, more like two thin booklets: Quick Start Guide which is a fold out guide, and a User Guide of 16 pages. This headset was a huge step up from the old Sony studio headphones I was using before, with their utter lack of bass and sensitivity. Cannot recommend the Uninex due to quality issues. I bought this it broke less than a week later. So far these earphones are okay. Still, my main issues with this are. Instead you get the 800 HX with silver face on the outside of the ear cups. Lol I installed it by myself pretty easy but I?m not sure if I stacked the bottom right or not because it leans a little bit over.
