MOONDROP ARIA 2 I purchased these and used them for only a few hours for burn-in. I am selling them because the sound quality wasn't to my personal taste. Includes all original accessories: earphones, earphone case, detachable cable, 3.5mm & 4.4mm interchangeable plugs, ear tips (S/M/L, one pair each), etc. These are wired earphones with a detachable cable (0.78mm 2-pin). You can enjoy both 3.5mm unbalanced and 4.4mm balanced connections with this single pair.
