Introducing the latest advancement in wearable audio tech - Firefly.2, the new IPX7 waterproof noise-reducing, dual-microphone headphones. The Firefly.2 is the best waterproof true wireless earbuds for athletes! The IPX7 waterproof rating means that a little water won't stand in your way from listening to music. The Firefly.2 true wireless earbuds is engineered for active lifestyle and provide high-quality sound and a secure fit for whatever sport you choose. While grabbing a top-notch pair of headphones for dry land is relatively simple, waterproof headphones require a little more research. Many are not waterproof and you can't just use a pair of waterproof wireless Bluetooth earbuds. Listen to your favorite music, all to the sound of your own beat! NOTE: Firefly.2 earbuds can be used for water sports such as Kayaking, Surfing, Yachting, Windsurfing but the signal will be cut if the Bluetooth connected devices (including Firefly.2 earbuds, smartwatch, mobile phone, etc.) are submerged in water.
