At 100 pops Canadian this hearing protection device is solidly overpriced. The muffs feel solid and have a proportionate weight to them. The cups are hard especially in cold weather making it uncomfortable to war for long periods of time. The cups are also shallow and house the battery and electronics, which push on the ear relentlessly while wearing. Passive noise reduction is mediocre at best even though the NRR rating is 24 dB. The headband is hard and inflexible. The cups can be adjusted to fit most size heads, but have considerable pressure due to the stiff headband, adding to the uncomfortable feeling of this set.
Sound enhancement is strong. At high settings the set can start squealing and develop a whistling sound. There is only volume adjustment although the package and manual describe adjustable frequency tuning. There is no provisions on the headset for manually tuning frequencies for base/treble adjustments. The manual is particularly shy on details. Fortunately the Alpha 360 headset is simple to operate and other than inserting batteries and turning the cups on, there is not much else to do but wear them.
Overall, the muffs do what it says, enhance sound and reduce the dBs of loud noises. Measured sound level in the cup during the firing of a 30 caliber rifle at 5 feet was 88 dB. Not great but enough to protect the eardrum from lasting damage. They are effective for short periods of time, due to the lack of comfort and the rate at which the batteries deplete. At full power, expect no more than a little over an hour of functionality.
Pros: Strong sound enhancement, high dB protection
Cons: heavy, uncomfortable, battery hungry.
