IPX5 防水級別， 為ST-XX提供額外的防汗和防水保護。
"These fully wireless earbuds were designed for listening on-the-go, wheter that means while you're working out at the gym, running down the sidewalk, or heading to the beach. They feature IPX5 weatherproofing for protection from sweat and rain, along with Bluetooth 5.0."
"They can last for about six hours on a single charge, though with the charging case that's included with the earbud's purchase, you can power them up anywhere to keep listening for up to 20 hours"
"Small in size, yet big on sound - a perfect combination for students, young adults and any SOUL fans looking to brighten their everyday listening experience with an accent of chic color at a cost-friendly price."
