These are rare true wireless earbuds with a 6-driver configuration. They feature a multi-driver setup of 2BA, 2PZT, 1 Planar, and 1DD, producing a slightly warm yet clear sound quality that is unexpected for TWS. I purchased them a month ago and have used them for about 50 hours. The exterior is very clean and shows no scratches, but there was some looseness in the charging case lid when I bought it new. The manufacturer said the warranty didn't apply, so I left it as is. It's not a problem for use. All accessories are included. Everything except the earbuds and charging case is unused. Operation has been confirmed. - Brand: GEEKFLY - Model Name: Vitas - Driver Configuration: 2BA + 2PZT + Planar + DD - Accessories: Charging case, ear tips, USB cable, instruction manual - Design: Blue marble pattern earphones
