Summary: For 1), there is NO on/off button, just a Hold switch that locks all the buttons but display ALWAYS stays on. 2), there is no shirt clip to keep it from falling out of your pocket or clip it to your pants pocket.
Summary: The only reason my rating is so low is because the seller included NO instruction manual....What I have figured out about the recorder is wonderful, but, there are many things I have no idea how to do yet.
Summary: Wow this recorder is great! I love how you can change the mic sensitivity and all of the options you have. The buttons are easy to use. For such a small and light recorder it has a ton of space. Like the others said, THERE IS AN OFF SWITCH.
Summary: I notice there are several reviews complaining about the lack of an separate on/off switch on the Sony B100. (The Hold button does not serve as an on/off switch.) However, the B100 does not need an on/off switch any more than does a digital watch. My watch is a cheap Timex digital.
Summary: I don't usually give bad reviews, but this product really deserves one. I am a reporter for a local magazine and needed a voice recorder to conduct interviews. I purchased this recorder and realized after reading and re-reading the instructions that it definitely does not have an On/Off switch.
Summary: This is the best recorder I have for recording EVP - not good for recording voices in large, echo-ey places, but is very easy to work with and I have had NO problems with it and it has been used and abused in all types of weather..
Summary: I use this to record lectures. It records. It plays it back. The sound isn't the greatest when listening to what was said, but if you put on headphones, that helps A LOT. If you want something small and digital that records with no bells and whistles, this is it.
Summary: I've compared the Sony ICD-B100 recorder to the Olympus VN-1800 which I bought a couple of years ago. Keep in mind this Olympus recorder is few years older than the Sony. One would expect, then, that the Sony is the superior product. This is not the case.
