Hearing Protection + Bluetooth Music & Calling Tasco Connex Bluetooth Earmuffs combine the best parts of hearing protection ear muffs and Bluetooth headphones to provide the benefits of both. That means you no longer have to choose between protecting your hearing and enjoying music and taking calls via Bluetooth. Connex Bluetooth is the best of both worlds. With Connex Bluetooth, you can talk and listen to music in high-noise environments, all while keeping your ears safe. NRR 25 Noise Protection Tasco Connex Bluetooth Ear Muffs provide NRR 25 noise protection. This is enough sound blocking to take the edge off of hazardous noise in an industrial environment. For the very loudest industrial applications, this may not be enough noise protection - but for most industrial workplaces, Tasco Connex's NRR 25 protection is enough to keep your ears safe and sound. Also, this is the perfect amount of protection for wearing Connex around the home and garden to mow, vacuum, or work with power tools. Connex Bluetooth is great for the industrial worker and the home DIY'er alike! Bluetooth: Stream, Call, and Listen Connex Bluetooth brings the best of Bluetooth to your fingertips. Pair Connex Bluetooth with your iPhone, Android, or any other smart device that supports Bluetooth. The Bluetooth works with up to an impressive 30' range, so you can make and take calls or stream your favorite music at a distance. No cords to get tangled up in here! Even the built-in microphone is located inside the ear cups, so there are no boom mics or wires anywhere to contend with. With Connex, your silhouette stays smooth and your hands stay free to move. Built-In Volume Limiting for OSHA Workplaces Connex is perfect for OSHA-controlled work environments thanks to its built-in volume limiting. This built-in internal volume limiting keeps sound to a safe 84dB. This ensures you cannot harm your own hearing, even when you listen to music all day every day. And it makes Connex an ideal solution for OSHA and NIOSH workplaces. Tasco Connex Bluetooth features excellent sound quality, so you can really enjoy your music while you work. With so much external noise blocked out, you will be able to enjoy highly detailed sound for an excellent listening experience (you may actually need to turn the volume down from where you're used to). Connex Bluetooth features simple controls that are easy to use. Up to a 60 hours battery life for continuous use (3 AAA batteries required). Attenuation Data
