I would like to recommend a voice recorder for listening to lectures and collecting evidence

Brothers! You have to talk about your needs and how much you plan to spend!

Needless to say, Sony's SX series has the best effect! **1500 to 2000, no matter how good it is, there are still Sony D50, the best thing about the current voice recorder! It's just a bit big!

I saw that there are already friends you mentioned to the outing! What to say! If it comes with its own speaker, it's best to forget it!

Just that little bit of something big, how loud do you expect it to make on its own!! If it comes to extrapolating headphones or speakers! What I said above, whether it is recorded or played, the effect is not good, you can scold me casually!

If it is about 1000, Sanyo is recommended!

No matter how cheap it is, it doesn't matter, really, half a catty or eight taels, it doesn't make much difference! Don't expect too much yourself! It is recommended to go to the store first to try out Sony's SX series things, and then try the others, if you think the effect can meet your basic needs at a low price, it is also good!

Finally, remind you, if you finally buy a high-end voice recorder, congratulations, you also have a high-end digital **** device, from then on you can try to say goodbye to *** this kind of lossy audio source, of course, the premise is that you are paired with the same grade of headphones (at least 300 up) and good sound source (buy your own genuine CD, transcribed in lossless format, a song is about 30 - more than 50 trillion).

Use the C90 of Sonlux to collect the voice recorder **Recording The important thing is that there is an external small microphone so that you can put it in your pocket The effect is very good I have a more than 300 bar It's okay I recommend you try it...

Depending on your economic purchasing power, the best is the Sony around 1000 or so.
