Main Features & PerformanceJBL
Pure Bass Sound: Tuned to deliver a punchy, warm, and V-shaped sound profile. Experts from RTINGS.com note that while the bass is powerful for pop and hip-hop, it can occasionally sound slightly muddy or less natural for purely acoustic tracks.
40-Hour Battery & Speed Charge: Provides up to 40 hours of continuous playback time on a single charge. A quick 5-minute emergency charge gives you an immediate 2 hours of playback. A full charge from empty takes roughly 2 hours.
Multi-Point Connection: Allows the headphones to connect to two Bluetooth devices simultaneously. You can seamlessly switch from watching a video on a tablet to answering a phone call on your smartphone without manual repairing.
Physical Controls & Voice Assistant: Built-in physical buttons on the right ear cup handle volume, track skipping, call management, and microphone muting. A quick double-tap activates Siri or Google Assistant.
