I haven't owned these buds for long; they have been used for 6 months and 20 days. The buds are fully functional. There are some light scratches, but the case is in fresh condition. The battery backup is good, and the buds have been used for 80 hours, 45 minutes, and 32 seconds. Everything is in perfect working order. It features Hi-Res audio, but it is LHDC; if your phone does not support LHDC, you won't be able to enjoy the Hi-Res audio. The box is included, along with the ear tips, but the cable and user manual are missing. Please don't bargain, as these buds are not available in the market but are in high demand.
