Will have to return this item. They look better with business attire and theyre just as comfortable. You know who I mean. I?ll definitely be repurchasing another pair in a different color, one size down. Last summer, I managed to lose a set of CX 300 Is bought 10 years back and am gutted as they were the best in ear buds Id ever owned. Itll make gaming and being interrupted while gaming, a much better experience. No instructions nothing else. I used a little grease on the threads of the clamp arm assembly when attaching it to the part which tightens it into the hub at the top of the upper tube. Due to this lock down situation where the gyms are closed, I wanted to do little exercise in my basement. I setup my band to always be tracking my heart rate, my sleep, brightness is set at max, with notifications for whatsapp, skype, slack and gmail, but I only use a non animated watch face (these can discharge your batt in about 2 days I believe)4 stars because its not very accurate in some of the most basic/desirable aspects of a fit band.
