Straight up one of the smoother experiences I had ordering online. Support texted me back within minutes each time. Buds looked exactly like the pics.
Solid experience overall. Prices was fair, delivery didn't drag, and the buds smelled loud when I cracked it open. Nothing crazy but nothing bad either.
