JBL Audífonos deportivos activos con cancelación de ruido Endurance Race 2 True Wireless resistentes al agua​​ 

Thanks for your question. The additional silicone caps included with our JBL Endurance Race 2 are provided in different sizes to help you find the most comfortable and secure fit. You can try each size to see which one seals best in your ear, this ensures optimal sound quality, bass response, and stability during movement. Simply remove the current ear tip and replace it with another size until you find the one that fits snugly without discomfort.

Thank you for your inquiry. Our JBL Endurance Race 2 has a top-tier IP68 rating, which means it is fully protected from damage by dust, sweat, and even submersion in water. However, they are not designed for swimming. The reason for this is a limitation of all Bluetooth technology: Bluetooth signals cannot travel reliably through water. When the earbuds are submerged, the connection to your device (like a phone) will be interrupted, and the audio will constantly cut out. So, while the earbuds won't be damaged by the water, you won't get a stable listening experience. They are perfect for intense, sweaty workouts or running in the rain, but not for use while swimming.

The JBL Endurance Race 2 offers up to 12 hours of playback time when Bluetooth is enabled and Active Noise Cancellation (ANC) is turned off. However, this can vary depending on the volume level and the type of music being played. For more detailed information about its playback time, please refer to the product's quick start guide, where the technical specifications can be found on page 17.
