The TREBLAB XR500 is a behind-the-neck wireless sport earbud built for athletes who need audio that stays locked in no matter how hard the workout gets. The secure neckband design distributes weight evenly and keeps the 11mm drivers sealed in your ears through sprints, burpees, and box jumps. IPX5 waterproofing handles sweat, rain, and even a rinse under the faucet after a muddy trail run.

Powered by Bluetooth 5.0, the XR500 pairs to your phone and smartwatch simultaneously. The 11mm dynamic drivers produce full, bass-forward sound that cuts through gym noise and outdoor wind, while noise isolation on the built-in microphone keeps your voice clear on calls. Nine hours of continuous playtime means your battery will outlast even your longest training days, and a 2-hour charge brings you back to full.

The lightweight 22-gram frame sits comfortably around your neck between sets without bouncing or shifting. Magnetic earbuds snap together when not in use so they stay secure around your neck. Three multifunction buttons provide quick, gloved-hand-friendly access to volume, track control, calls, and power. The 20Hz-20kHz frequency response delivers punchy lows and clear highs for every genre from hip-hop to electronic to hard rock.

Whether you are training for a marathon, crushing a HIIT class, or just running errands in the rain, the TREBLAB XR500 is the sport earbud that refuses to quit. Durable, sweatproof, and tuned for movement.
