Nice little recorder


from wisconsin

I bought this prior to starting nursing school and I love it. You can name audio file folders on your comp and they will display on the device ex. pharmacology and skills folders to sort lectures. The battery included is rechargeable and it recharges via USB + it comes with headphones!! I've tried a few others and this is hands down the best of the lot. I know i shouldn't get excited about a voice recorder but this thing is great.

    Good for the price


    from Woodstock, IL

    I bought this to record speeches, i put it in my shirt pocket and it does a good job. you have to play with the settings to get the best sound for the room you are in. It has many features to eliminate background noise and multiple Scenes can be programmed so you can switch quickly between settings for different environments. The recorder does support Power on plug for the small lapel microphones. Some recorders require that you use an inline battery to power the mic. It would have been nice to have a version available with the dragon software. The Software that comes with some of the other recorders is a cut down version of Dragon naturally speaking. If you want to do speech to text you will have to purchase the professional version of Dragon naturally speaking to do transcription. The transcription feature is not available in Dragon Home version. If you want the transcription function i would recoment you buy the SX712 with Dragon software included. The built in USB is nice, saves you carrying cables and trying to find them. The included sound organizer software works great, but you can use windows media manager or othe programs to do the same thing. The recorder will also function as a music MP3 player to let you listen to music or books and have one less thing to carry around.

    Poor Quality Recording Hard to Use


    from Pasadena

    I just bought this recorder all I can say that the quality of the recording is poor. I am also having a difficult time trying to use the VOR feature since that's the reason I bought it to protect myself from malicious comments.
