I did get a splinter though before I did any of the assembling and immediately took some sand paper and gently sanded sporadically around it. I?m not really an ?audiophile? but I do spend a significant amount of time wearing these and I must say the quality and comfort are very good. The phone has a beautiful bright crisp display and runs super smooth opening and closing apps and volume is clear. Ive owned it for a year and its great. However, like most other Under Armour compression shirts that Ive purchased this shirt constantly rises from the waist while Im working out. These definitely beat out many of their wired rivals. The connectors that you attach to the controllers I thought might be weird or annoying but I hardly notice them and it is much much easier putting the controllers back on the charger (no wiggling them around to get them seated). Ive had these earbuds for many months. this unit is still worth it ! This is the most negative thing about the headset.
