Additionally, because the ear cups of HPDs form very tight seals around the ears, you’ll find that they suffer a lot of proximity effect, which results in muddy bass that overpowers other frequencies. You can also use the Walker’s Link app (on iOS and Android) to monitor battery levels and set program settings. It’s clear that hearing protection devices (HPDs) are essential if your workplace or hobby has high levels of noise.

In any case, I prefer the sound and volume limiter of both 3M Worktunes earmuffs and the Howard Leight Sync Stereo for listening to audio in a loud environment. Battery life: With the MPow BH203 Bluetooth receiver, I got about 15 hours of Bluetooth listening (built-in rechargeable lithium battery). The noise reduction rating (NRR) for these earmuffs is very similar (NRR 24 and NRR 25, see table below).The Peltor Sport Tactical 500 earmuffs offer reliable hearing protection, excellent comfort and have essential features ideal for recreational shooting. This gives you greater flexibility because you can opt for a longer-lasting battery depending on your specific needs. They don’t sound as good (they lack bass) as the 3M earmuffs but I can still get a lot of fun out of them.

Telephone headsets are a must for businesses large and small, increasing productivity and efficiency. Some podcasts and audio books and quieter music were more difficult to understand in a high noise environment (>95 decibels) than with the other earmuffs reviewed here. They provide the most space for the ears and plenty of adjustability for most heads, and they reduce noise well.This works OK in a quiet environment, but the louder the environment, the more disturbing this “hear-through-function” gets. Noise reduction in mics uses one of two technologies: Digital Signal Processing (DSP) or Clear Voice Capture (CVC).
