Is there any protection if the batteries die on you in the field/range? I.E. What happens to noises above the 82dB range with no batteries?

I've turned off the power to the Ear Muffs and you can't hear much. I guess they are about the same as a non-powered ear muff. But with the power on and set, they work great. you hear everyone around you, but when there is a gun bang, it shuts most of it out. I don't know how they do it, but it works great!

If the batteries die or you leave them on and forget(as I have done) They will function as regular ear protection but they will lose the ability to amplify regular sounds. Basically the best part about these is the ability to hold normal or even whispered conversation and hear really quiet noises such as twigs breaking or footsteps in the snow. To restate my answer they would be great ear pro even if they were dead- Chris

They work just like any ear muffs. IF they are powered, they will be able to amplify the sounds you want to hear. Without batteries, you don't lose any protection, only the ability to hear what ear muffs normally block out.

Keep a spare set in you range bag. If you forget to turn off the switch, the unit goes off automatically in 4 hours.

The earmuffs have a NRR (noise reduction rating) of 22 dB. If you wear a set of ear plugs under the muffs, you should get in the range of 32.

The seem to be just normal earmuffs blocking 82db and above when there are no batteries but I can not say this for sure because I have not field tested them without the batteries. My guess is that they work the same when there are no batteries or if they are dead, as they do when the volume is turned down while they are on; they cut out 82db and above without amplifying sounds below that range...

Thanks to everyone for helping other customers by sharing your experience. If anyone is having issues with the sound cutting out, please email us at support@66audio.com - this is not normal and if you are within range (20-30 feet) and your battery is charged and not low, sound will not cut out!

Hi If you need the muffs to cut noise the are great but the battery part of the muffs are no good. I could not tell if it does anything. The batterys were not hard to replace. The length of batt. use would depend on how much they were left on.

I actually have not used the speaker with just the batteries on. I have been using it plugged in all the time.I am now curious to see if that happens if I tried it with just the batteries. It could a power saving mode.

Have not encountered that,fortunately,did realize that it doesn't work well with low battery,and range is more like 8 feet,I suggest you contact manufacturer,sounds serious.

Batteries seem to die quickly, especially on high. It does work well and it keeps the dogs quiet for sure, however, when on high, it also reacts to other loud noises, and if you have a lot of wind and stuff bangs and rattles around, or other environmental noises, it will drain faster. My husband built an inexpensive solar unit for one of our units however and is in the process of making them for the other one too. Works AWESOME now and no more draining of batteries!

Yes, you can still listen to music without batteries. No, the headphone doesn't "quit" when the battery dies.

You can put batteries in the speakers and take them a little way off. I use them around the pool.

no, batteries only. Sound only average...or below. In addition, I live in an urban area where the reception should be elevated, would not recommend it. Bear in mind that most of these electronic creatures are now made in China, sadly always a downgrade!!!!!

None what so ever, I have mine in the basement under the kitchen in a joist cavity and no issues. You can always place a layer of bat insulation in the cavity to prevent further. There is not much bass generation mostly directional surround of mid's and tweets.

I can only speak for the chime setting because we do not use the alarm. If the batteries are running low the chime won't work all the time, its sporadic. With fresh batteries I have had no issues. When the batteries are running low you get a warning, the chime only plays the first portion of the song, then it makes a low battery beep. This will go on for days or weeks until you replace them. The longer you wait the less reliable the chime is with the old batteries being used.

Sound great. I use mine without batteries most of the time. Turning them on does add a little bass boost.

David C. The only sound that is made is the ones that let you know the unit is on/off/bad battery. These are simple beeps and a light indicator. During operation in the field...nothing, Great product! Mine is over two years old and is still going with no issues other than new batteries. Tom

It sounds defective. I ran mine over 2 nights camping, using a small rechargeable 12 volt battery. I only heard the alarm once towards the end of the second night when I dropped below 12v. I thought it was a great lite unit for the price. I used 12 strings of LED lights around my campsite and people were amazed at the effect.

There is a cutoff and I believe that the unit automatically dissipates the charge slightly if the batteries are left in the unit beyond the charge up time.The marketing blurb states " Automatically protects against overcharge and short circuit." The only danger I remember is in leaving the unit on with no batteries in it at all.

yes, but as long as no one else is talking. you will hear everything.i have two of them one in my pocket for back up. instead of thing to replace the battery right there.

Great mine are outside also. We purchased a small acrylic box at the dollar store. Any size would do. This is one heck of an item for the price. You will not regret purchasing it.I think I misunderstood. The transmitter can not be placed outside. But the sensors can be. I am not sure if the transmitter could withstand the outside without protection. Direction tell u not to put them outside. I am in Fl and the sensors are exposed to the heat, sun, etc. enjoy it
