Yes. 1 very loud beep. That same beep also beeps on 3.2.1. to start the workout.

No, it doesn't make any noise. It is a very good buy. I have two king sized and am very pleased with the quality, size and price.

yes it does, it just sometimes would countdown but not buzz. It wasn't consistent.

I have mine set on timer and it does buzz when it comes on. It seems to be operating correctly and it doesnt bother us as its in the master bedroom.

Mine does not make noise. If you put it against your ear there is a faint buzz. But nothing to be alarmed about or a nuisance to use.

You can set it to buzz when the light is completely on. Or you can have no buzz at all. If you set it for 7 AM, and you set the "sunrise" for 30 minutes, it will start to light up at 6:30 AM and get brighter and brighter. If you have the buzzer set, it will buzz at 7. If you have the buzzer turned off, you will have only the light to wake you up.

It doesn't hum or make noise. It's bright enough to read by, it definitely doesn't light up a room. It just has an on/off switch. It's pretty light weight.

It was a gift for my MN daughter. So I called her and she said she thinks all electronics make some slight sound but she never noticed a buzz or anything that bothered her. She loves it but hasn't been using it yet this winter so she doesn't remember. I gave it to her last February 2014.

No, it makes no noise it all. It has two lights (red green) that indicate charging or not and when it is not it flashes back and forth.

When it is functioning correctly, it simply beeps when time is up. Optionally, one can set the unit to be silent and/or optionally blink the user lights when time is up. Warning: this unit uses a cheap wiring inside which leads to the unit eventually resetting itself after moderate use. I have two of them, and they both have the same problem, so I don't recommend it.

Mine is noisier than I would expect at times, but nothing that has caused me too much alarm. I thought I heard it click a few times, but so far nothing reproducible or any overheating.

If I charge it at the same time, it will have the buzzing sound. Otherwise, it is perfect and sound great.

Mine makes the same buzzing sound, I have had it for about a year, however, it still works perfectly well. Just hold your finger on the on button for 2 seconds or so, or just press it again for a second to ensure that it is on.

It has a low and high volume choice to wake on buzz. I have used the high volume and it is not excessive. Have not noticed if progressively gets louder or not. And I have not tried it to music. I have used at a party to play music and worked very well. Hope this helps in your decision.

No. I've never heard my beep. It beeps when you plug it in and as you set the timer. I don't use the light feature so I don't know if that makes a difference or not.

Mine really doesn't make noise, and when it's empty, it automatically shuts off, but doesn't give a warning.

Mine does not do that. I have never noticed a buzz. My earpiece output is loud and clear.
