The JBL Reflect Flow are ideal earbuds for athletes. Thanks to the completely wireless design, there are no cables in the way, and the IPX7 certification means the earbuds are waterproof. This prevents water damage due to sweat or rain and allows you to keep the earbuds under water for a short time. Have you planned a long workout session? The earbuds last 10 hours on a full battery charge, which is longer than with comparable fully wireless earbuds. When the earbuds are empty, you can charge them within 10 minutes and use them for another hour.
