Nova1Star Transform any space into a focused learning zone. Advanced Hybrid Active Noise Cancellation cuts up to 90 % of background sound, helping sensory-sensitive kids concentrate in class, on flights, or while studying. A single button with voice prompts makes quiet time simple—even for toddlers. Protect young ears with a parent-controlled volume limiter. Three precise levels adapt to every situation: 75 dB for bedtime, 85 dB for daily use (WHO-safe), and 94 dB for clear listening in loud places. Ultra-soft memory-foam cushions, breathable hypoallergenic fabric and a feather-light 280 g frame provide pressure-free comfort for hours. The BPA-free build is safe for delicate skin. Power through a full week of learning with up to 70 h of playtime (40 h with ANC). A 10-minute USB-C quick charge adds 4 extra hours, and the included 3.5 mm cable keeps music going even when the battery is empty. Bluetooth 6.0 and a high-sensitivity microphone deliver studio-clear audio and voice pickup for online classes and calls, keeping kids connected to every lesson on tablets, laptops and phones.
