FEATURES

• Perfect Workout Companion: Spirit 2 Bluetooth headphones fuel grueling workouts with hard-hitting music powered by oversized dynamic drivers that are 40% larger than standard ones. Their composite bio-cellulose diaphragm is lightweight, yet stiff to produce highly-detailed treble, and is surrounded by an ultra-elastic material capable of stronger vibrations to increase bass output by up to 50%.
• Thumping Bass: Our exclusive BassUp technology uses a custom algorithm to conduct real-time analysis and instant bass intensification. It’s paired with acoustic mesh over the acoustic chamber that further boosts low frequencies to gives you the motivation to reach the finish line.
• Everything-Proof: Spirit 2 Bluetooth headphones boast IP68 dust and waterproof protection; which allows it to be submerged in up to 1.2 m of water for 40 minutes; as well as our exclusive SweatGuard technology. We’ve created an industry-leading sealing process and hydrophobic nano-coating that stops sweat vapor from breaching the casing. It even makes the USB-C port waterproof when it’s left uncovered.
• Zero-Pressure AirWings: When you put Spirit 2 in position, the hollow structures made of ultra-flexible, soft silicon react to the shape and size of your ears by partially deflating. By conforming to the unique shape of your ears, the pressure-free design feels weightless for a truly personalized fit, unmatched comfort, and a secure hold.
• Note: This product is not currently compatible with iPhone 11 series, but is being upgraded.
