Headphones

I have win7 64Bit and use Audacity and I will be making PodCasts.

I am looking for a Headset with a Microphone and I want it to be USB.

I found Logitech H390 because the Mic had a FREQ. of 100Hz to 10kHz.
And the Headphone Speakers had a FREQ. of 20Hz to 20kHz.

I know we can not Hear 20Hz to 20kHz but it is the Full FREQ. so I would like to have it.

And the Heaphones Cups Rotate.

But the more I read and watch on them they say they are bad.

I need them to Listen to Music and good sounds as well.
And I do need a good Mic so I wanted to get an all in one.

Can you help?

 

You need to do the searching and reading of reviews yourself. Just do a simple internet search for: USB Headset with microphone reviews
and you'll get multiple results, like this one:

Speakers (including headphones) are very subjective. Plus, with head phones, they have to feel good on your head. So before you buy, try to find some place where you can try them on. This is especially important if you will be wearing these for several hours at a time.

You also need to decide if you want over-the-ear, on-the-ear, or in-the-ear. Each has their own set of advantages and disadvantages. Then there is wireless or corded.

Do not get stuck on published specs of 20 to 20. Understand achieving a full spectrum, "flat"20Hz to 20KHz response with minimal distortion is almost impossible even with traditional, full sized loudspeakers costing many $1000s each.

Note while hitting the 20 or the 20K is doable, it is the flat (±dB) response with minimal distortion that differentiates good "sounding" head phones from poor sounding.

Your listeners sure won't hear the difference.
