3M WorkTunes Connect & Solar proteção auditiva sem fios Bluetooth com função de carregamento solar 90570E-1

The 3M WorkTunes Connect & Solar combines hearing protection with wireless audio and a solar charging panel, so you can listen to music or take calls while reducing harmful noise on the job. Unlike standard earmuffs, it integrates Bluetooth and a rechargeable battery that tops up from sunlight or indoor light, extending playtime without frequent plugging in.

Highlights

• Bluetooth 4.2 wireless streaming and hands-free calling via built-in microphone
• Integrated solar panel supplements the rechargeable lithium-ion battery
• Up to 30 hours of Bluetooth playback on a full charge
• USB-C charging port and 3.5 mm AUX input for wired devices
• SNR 31 dB attenuation (H=34 dB, M=28 dB, L=21 dB) for noisy environments
• Padded headband and soft ear cushions for all-day comfort
• On-ear controls for volume, play/pause, and call answer/end

In daily use

Pair your phone once and the WorkTunes Connect & Solar reconnects automatically. The controls are easy to reach even with gloves, and the voice assistant button lets you manage music or calls without removing the earmuffs. When the battery runs low, place them under a light source to trickle-charge via the solar panel, or use the USB-C port for a faster top-up.
