Question: will fm radio work on 87.7 as this is the frequency used at Silverstone race course in UK
Document: Pleased to announce that the radio, external mic, and the aux unput can all be used siamotainously (I was not sure if that was possible from reading the description). This is awesome if your noisy job requires you to monitor a two way radio. These muffs protect your ears while enabling you to hear your surroundings, listen to the radio, and monitor your two way all at the same time. Awesome if you work at an airport!
The ambient sound mic is a nice addition too. My big complaints are that they are too tight, the ear cushions could be softer, and the dial tuner is very narrow in its reception range. You have to pin point the station you want by moving back and forth until you are right on the frequency. A digital tuner would be better. That said, they work and I am happy with them.
I was looking at hearing protection and decided on these. I had a pair of the basic am/fm headset last year and by the end of the summer they stopped working. I figured i would step it up a notch and see what crazy thngs were available.I am in landscaping and run power equipment almost all day long. The last pair i had made work more enjoyable, but these are a lot better. They seem to come in better and there is hardly any static between stations.
These headphones met my expectations plus some. The noise cancellation is great and the fm radio reception is great. I have not tried am radio. There is some feedback noise with the radio and electronic listening capability turned on at the same time. I do not plan on using a mp3 player with this set so the need to buy a separate cable is not an issue for me.
If you are looking for am AM/FM headset to take to the race track or to use with your scanner DO NOT BUY THIS HEADSET ! ( Besides having to buy  a special 30 dollar connecting cord) This product will not work with a power spliter.The "drift" on the Feq. dial is horrible. (if you can even find the station )!& the dial has NO numbers so the AM/FM STATIONS ARE TO FIND. For 100 dollars you get 50 dollar quality.
I have another friend who has used this headset and said it blocked out the sound of hammer blows while he was able to talk to a co-worker. Cool! I like these better than any other radio headset I have purchased.
I have used these head phones for a few months now and I really like them. They are excellent at blocking noise. When I first put them on, I thought that they were too tight, and that I wouldn't be able to wear them for very long. This has turned out to not be an issue. They are comfortable even if I wear them all day.The stations come in clearly even in the shop where I have had trouble with other radio headphones fading in and out.
I bought the 3M Peltor Alert Hearing Protector with AM/FM Tuner (M2RX7A) to use while cutting grass. I used them the first time and they worked okay for about an hour and then the radio just quit working. The batteries were not dead because to took them out and tested them with a volt meter. While it was working the radio knob was too sensitve making it difficult to adjust to stay on a station.
This set of radio headphones are total junk. Avoid and do not purchase this product they're not worth $40.00 much less $128.00. There is no radio dial or reference for frequency and they are cheap and poorly made with poor reception to boot.Total crap DO NOT EVEN THINK OF WASTING YOUR MONEY ON THIS JUNK.
Ordered after my contractor swears by them. Had the headsets for 4 months and the radio has stopped working, of course just after it becomes non-returnable. They were great for as long as they worked, just not very reliable. Also, the radio dial does not show what channel you are on, so its just turn and guess.
Answer: yes
