Extremely disappointed.Falsely advertised as Bluetooth ear muffs.These are not Bluetooth or electronic.They are passive ear muffs.I am now out of the country or else would have sent them back for a refund.

La he utilizado durante todo un año y no se ha averiado. Alguna vez, suena muy alto ( supongo que es un error de software ) que se se soluciona regulando el volumen del sonido otra vez. Por lo demás, me ha ayudado a soportar los ruidos y las conversaciones del trabajo mientras escuchaba algún podcast.

Wanted to wait a while before writing a review and i have now owned these for close to 2 years. I like the double aa batteries because if I’m working and they get low i can just put new ones in instead of charging the headphones. Highly recommend rechargeable double a’s if it makes sense for your use case. They still work great. I get many hours on the double a batteries. Never had a problem with bluetooth and I listen to music probably every other time i wear them. I probably use them 4 days a week for reference on how much abuse they get. They've survived several falls at around 6 feet over the last year and a half. The head strap has nicely sized cutouts if you wear a ballcap while you work and i find the ear muffs comfy. The noise amplification is nice, i can hear what sounds my tools are making or people talking to me when i need to and then switch the setting to make everything go away when i don’t need it. I live and work in a warm climate- they get pretty sweaty but the ear pads havent gotten gross yet. It is not an excessive amount of heat compared to other over ear headphones, but i feel that the cooling pads don’t really make a difference unless the air temperature is pretty cool (~60f or lower). Sound quality is super good enough and, honestly, I wouldnt change much. It’d be cool if they were a little lighter and folded for storage but otherwise they are great. Just remember to turn them off so you don’t waste your batteries.

My husband needed some noise canceling headphones for work in a loud environment and he said these are great! He can listen to his music and here any messages or calls from his phone.

They were very comfortable and could be worn all day. I liked the fact that the two AA batteries could be swapped out when they died and didn’t need to be removed or charging. (I had four rechargeable batteries.) They could be worn as normal earmuffs when off. The noice cancelation did work when turned on. I could hear conversation but when loud machinery was in operation the loud noise was lessened significantly. They connected to my iPhone via Bluetooth easily and I used Spotify to listen to music. I was able to take calls on them but the noisy environment that I was in made this difficult. However, i was aware a call was incoming so I could go and take the call instead of missing the call. There are well documented issues with white noise when they are on. Not noticeable when music is playing unless soft or quiet music is playing. Again, very well documented on the net, the triple volume mode does not work at all and did not from new. You had to adjust the volume via the phone. I was willing to put up with these two flaws but… Latterly a very loud electronic screech when turned on made them completely unusable. They were just very expensive earmuffs. I purchased these from a UK seller on Amazon.co.uk who unbeknown to me purchased them in the USA and shipped them to me. I contacted 3M about my issues but they would not help because they were an American import. These are no longer being made, I suspect due to the well documented issues which I only found out after the faults became identified. You have been warned, DO NOT BUY!
