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: Has good features such as being able to Bookmark an area whether in record or playback mode. Setup is simple, instruction sheet is probably necessary for those not too good at figuring out electronic equipment by trial and error. Ease of use is good.
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: With its compact design and intuitive features, the Sony ICD-B100 was just the device I needed to carry with me for recording quick memory joggers that I'd normally tend to forget. Its use is easy, and multiple folder features actually makes sorting out what is recorded simple.
