3M Pro-Grade Noise-Reducing Earmuff, NRR 30 dB, Lightweight and Adjustable, Black/Red, One Size

The 3M WorkTunes Connect earmuffs are designed for use in noisy environments, such as yard work or power-tool usage. They reduce noise through thick layers of foam rather than electronically cancelling it out. They offer a 30 decibel noise reduction rating, which makes them suitable for shooting ranges or loud nightclubs. However, since they are large and boxy, they may interfere with using stock weapons. The noise reduction is effective for loud equipment, with the music still audible over the noise. The external microphones are adjustable with four different noise levels, and there is a boom mic that is adjustable and can pivot in all directions. They are difficult to adjust and probably not suitable for children. They come with a headband made of uncushioned rubbery material, which is comfortable and durable. They are perfect for people with larger heads, though not recommended for shooting since they cannot be held properly. They come with batteries, but customers would prefer plug-in rechargeable ones. Some customers complain about white noise when the headphones are turned on, and others found them to be mediocre at blocking out environmental noise. A few customers had issues with Bluetooth connectivity and sound quality. Some found the plastic brittle and they broke easily. The warranty was not effective in some cases.
