JBL Sound Fit (Transformable Design): This is the headline feature. The earbuds come with two types of ear tips: "Open Ear Tips" for a natural, aware feeling that lets in surrounding sound, and "Sealing Ear Tips" (in 3 sizes) for better noise isolation and a secure fit. You can swap them based on your activity .
Active Noise Cancelling (ANC) with Smart Ambient: With the sealing tips, the earbuds use a 2-mic system to reduce background noise. The Smart Ambient technology includes Ambient Aware (so you can hear your surroundings without removing the buds) and TalkThru (which lowers music and amplifies voices for quick chats) .
JBL Pure Bass Sound: Equipped with 12mm drivers, they are tuned to deliver the signature JBL bass-heavy audio profile .
Battery Life & Speed Charge: You get up to 32 hours of total playtime (8 hours in the buds + 24 in the case) with ANC off. With ANC on, it's 6 hours in the buds + 18 in the case. A quick 10-minute charge gives you about 2 hours of playback .
Clear Calls: The earbuds feature 4 microphones in total to ensure your voice is picked up clearly during calls. The VoiceAware feature also lets you control how much of your own voice you hear during a call .
IPX4 Water Resistance: They are splash-proof and sweat-proof, making them suitable for workouts or light rain .
JBL Headphones App: You can use the app to customize the sound EQ, adjust touch controls, find your earbuds, and switch between the ear tip modes for the best performance .
